Best RV Leveling Blocks: 10 Interlocking Sets That Stack

RV leveling comes down to one question: how does the block meet your tire or jack? These ten picks split on that — flat interlocking pads you stack, curved ramps you drive onto, and wide blocks built for dual tires. The rest is set size, stack height, and what the seller covers if something cracks.

Best overall: Lynx Levelers 11 Pack — the original modular block, rated to 40,000 lbs, sold with a cap top and a nylon bag since 1992. Best fastest setup: CARMTEK Camper Leveler Kit — a curved leveler with chocks and rubber mats, leveling anywhere between 1/2″ and 4″ in under five minutes. Best for dual tires: Camco FasTen 4×2 — 17″ x 8 1/2″ blocks shaped to sit under two tires at once, with an integrated locking handle.

The rest of this guide walks through every set, who each one suits, and what to check before you order.

How We Picked

We kept the listings that state real numbers: block dimensions, stack height limits, load ratings, and what actually ships in the box. A listing earned a place by naming its material, its compatibility, and its warranty terms in plain text — not by photos or slogans.

1. Lynx Levelers 11 Pack

Lynx Levelers 11 Pack

Check Price on Amazon

Best for: the first-time RV owner who wants one proven set

This is the set that started the category, made in the USA since 1992. Each block measures 8.5″ x 8.5″ x 1.5″, and the listing says the interlocked height is 1″, so a stack grows in one-inch steps. The cap top is 8.5″ x 8.5″ x 0.5″ and adds just 0.25″ once interlocked.

That cap is the detail worth understanding. It sits on top of your stack and takes the tire contact instead of the block body, and it barely changes your height. For a trailer that needs a small correction, that quarter inch matters more than it sounds.

It isn’t the set for someone who wants to drive on and go — you stack these by hand before you back up.

Pros

  • 40,000 lb load rating stated
  • Cap top adds only 0.25″
  • Nylon storage bag included

Cons

  • Manual stacking before every park
  • No chocks or ramps in the pack

2. Camco FasTen RV Leveling Blocks

Camco FasTen 10-Pack

Check Price on Amazon

Best for: the buyer who wants a handle built into the blocks

Camco’s FasTen blocks measure 8 1/2″ x 8 1/2″ x 1 1/2″ and use a quad-grid internal structure the listing describes as load bearing. The standout feature is the integrated T-handle: lift it to carry the stack, twist it into the base block to lock the set together.

The listing is unusually clear about one limit — don’t stack these too high. That’s the number to remember, because it caps how much slope this set can correct. Past that, you need a ramp or a different approach.

Compatibility is broad: single wheels, double wheels, tandem axles, and hydraulic, tongue, stabilizer, and fifth wheel jacks. It pairs with Camco’s other leveling pieces, so a mixed kit grows without adapters. Patented and made in the USA.

Pros

  • Integrated T-handle locks the stack
  • Works with wheels and most jack types
  • Patented design, made in the USA

Cons

  • 4 ½” maximum stack height
  • No storage bag or cap in the pack

3. RVMATE 12 Pack RV Leveling Blocks

RVMATE 12 Pack

Check Price on Amazon

Best for: the camper who wants spare blocks on hand

Twelve pieces ship here: 10 leveling blocks at 8.5″ x 8.5″ x 1.5″, 2 top blocks at 8.5″ x 8.5″ x 0.75″, and a carrying bag. Each block adds 1″ of height per the listing, so the two top blocks give you a finer step than the body blocks alone.

The top covers are the practical part. They sit between the tire and the block body, which the listing says reduces compression wear on the tread. If you level often, that’s the difference between replacing a worn cover and wearing your tire.

The blocks work with single wheels, dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks, and fifth wheel jacks. The set is built around stacking — there’s no ramp here, so tall corrections take more blocks, not less effort.

Pros

  • 12 pieces with 2 top covers
  • Top covers reduce tire tread wear
  • Carrying bag included

Cons

  • No chocks or ramp in the set
  • Tall stacks need many blocks

4. OULEME 12 Pack RV Leveling Blocks

OULEME 12 Pack

Check Price on Amazon

Best for: the buyer who wants a bag and a spare top block

OULEME ships a set of interlocking blocks with matching top blocks, each body block 8.5″ x 8.5″ x 1.5″ and each top block 8.5″ x 8.5″ x 0.7″. The listing states each block is one inch tall in the stack, so height builds in even steps.

The material note is the one to read closely: polypropylene with anti-UV aging additives, plus denser and thicker structure. UV additives matter because these blocks live outside in summer sun, and sunlight is what makes polymer brittle over years.

The listing covers stacking for RV leveling and use under trailer jacks and stabilizers. Beyond that it stays general — there’s no load rating printed and no stack height limit given, so treat the seller’s own guidance as your ceiling. A carrying bag is included.

Pros

  • 12 pieces with cap tops included
  • UV-resistant polypropylene stated
  • Carrying bag included

Cons

  • No load rating printed
  • No stack height limit stated

5. CARMTEK Camper Leveler Premium Kit

CARMTEK Camper Leveler Kit

Check Price on Amazon

Best for: the traveler who wants to level in minutes

This is a different tool. Instead of stacking pads, you drive the tire up a curved leveler until the trailer sits level, then wedge the chock behind it. The listing says you can hit any increment between 1/2″ and 4″ in less than five minutes — no counting blocks, no guessing.

The jointing system is the clever part. Grip channels on the leveler line up with notches on the chock, and the listing says the heavier the RV, the more channels engage. That’s what stops the chock sliding out while you’re parked.

The kit is rated for trailers up to 35,000 lbs and tires up to 32″ diameter, and it carries a lifetime warranty with free replacement or refund. One catch: on some dual axle trailers you may need to cut a leveler to length, up to 4″ off, to fit between tires. The listing includes instructions for that.

Pros

  • Level in under five minutes stated
  • Lifetime warranty with free replacement
  • Chocks, rubber mats, and bag included

Cons

  • Some dual axles need trimming to fit
  • 35,000 lb and 32″ tire limits

6. Camco Fasten RV XL Leveling Blocks

Camco FasTen XL

Check Price on Amazon

Best for: the owner of a larger trailer or wide tire

Same FasTen system, bigger footprint. These blocks measure 10 1/2″ x 10 1/2″ x 1″, so there’s more surface under each tire than the standard 8 1/2″ version. The listing points that width at larger trailers specifically.

The T-handle works the same way: lift to carry, twist into the base block to lock the set and collapse the handle for storage. The quad-grid structure is described as load bearing, and the same 4 ½” stack limit applies here — don’t go higher.

Compatibility covers single and double wheels, tandem axles, and hydraulic, tongue, stabilizer, and fifth wheel jacks. One honest note from the listing itself: colors may vary because of changes in the manufacturing process. If matching gray matters to you, that’s worth knowing before you order.

Pros

  • 10 1/2″ x 10 1/2″ footprint for larger trailers
  • Integrated handle locks the stack
  • Patented, made in the USA

Cons

  • 4 ½” maximum stack height
  • Color may vary from the photos

7. Lynx Levelers 22 Pack

Lynx Levelers 22 Pack

Check Price on Amazon

Best for: the full-timer who levels often and wants spares

This is the big version of the original. Twenty blocks, cap tops, and nylon storage bags ship together, and the blocks carry the same 40,000 lb rating as the smaller pack. Each block is 8.5″ x 8.5″ x 1.5″ with a 1″ interlocked height.

The warranty is the headline difference. The listing offers a 10 year manufacturer warranty — register the product, and if something goes wrong you snap a photo and get a replacement. That’s a long window for a piece of plastic you drive a trailer onto.

The included bags mean you can split the set: one for the trailer, one for the garage, or one for each axle side. It’s more pieces than a weekend camper needs, and more to store when the season ends.

Pros

  • 20 blocks and cap tops
  • 10 year manufacturer warranty
  • Storage bags included

Cons

  • Large set to store between trips
  • No chocks or ramp included

8. BUNKER INDUST RV Leveling Blocks/Stackable Jack Blocks

BUNKER INDUST Leveling Blocks

Check Price on Amazon

Best for: the owner who levels and jacks from a single kit

BUNKER INDUST sells these as a dual-purpose set: leveling blocks and jack support blocks in one. Instead of packing separate pads for your stabilizers, you use the same blocks, which cuts down what lives in the bay.

The listing states a 15,000 lb load capacity at 7.7 lbs for the set, and says the polypropylene resists UV, water, and extreme temperatures. A 15,000 lb load capacity, so check it against your trailer’s weight before you commit.

Stacking is modular and tool-free — stack, level, drive on. They support pad, post, stabilizer, and wheel jacks, and a storage bag is included.

Pros

  • Dual purpose for leveling and jacks
  • 15,000 lb capacity stated
  • Storage bag included

Cons

  • 15,000 lb rating is the lowest here
  • Ten blocks, no cap top included

9. Lynx Levelers 6 Pack

Lynx Levelers 6 Pack

Check Price on Amazon

Best for: the light trailer owner who needs a small correction

A compact set of blocks, nothing else. The listing gives two clear uses: arrange them 3-2-1 for a pyramid up to 3.5″ for leveling, or build a straight stack up to 6.5″ for stabilizing. That’s the whole product, and for a small trailer or a single low corner it’s enough.

The 3-2-1 pyramid is the useful shape here. It gives you a wide base and a stepped top, so a tire rolls up one step at a time instead of climbing a wall. For stabilizing a tongue jack or a step, the taller straight stack is the option.

This is the set to skip if you have a heavy rig or a campsite with real slope. Six blocks run out fast, and there’s no bag, cap, or chock in the box. For a teardrop or a small camper, it covers the job.

Pros

  • Pyramid to 3.5″ for leveling
  • Straight stack to 6.5″ for stabilizing
  • Small and easy to store

Cons

  • Only 6 blocks, no extras
  • No storage bag included

10. Camco FasTen 4×2 RV Leveling Blocks

Camco FasTen 4x2

Check Price on Amazon

Best for: the dual tire owner who wants a single wide block

These blocks are 17″ x 8 1/2″ x 1″ — long enough to sit under both tires of a dual wheel setup at once. If you have ever tried to line up two separate pads under a dually, you already know why that shape exists.

The rest is standard FasTen: integrated T-handle that lifts to carry and twists to lock the stack, quad-grid load bearing structure, and the same 4 ½” stack limit as the other Camco sets. Compatibility covers single wheels, double wheels, tandem axles, and hydraulic, tongue, stabilizer, and fifth wheel jacks.

Ten blocks ship in gray. The long footprint means fewer pieces per axle than square blocks, but the shape is specific — on a single wheel trailer you’re carrying length you don’t need.

Pros

  • The long length fits dual tires in a single block
  • Integrated handle locks the stack
  • Patented, made in the USA

Cons

  • 4 ½” maximum stack height
  • Long shape is overkill for single wheels

Also Worth Considering

Three more sets sit just outside the top ten. The WELLUCK RV Leveling Blocks Pack ships 12 pieces with two Velcro straps to hold a stack together in transit, and covers single and dual wheels. The Homeon Wheels RV Leveling Blocks is a 10-pack with a non-slip surface, aimed at campers who want a simple stack. The PAULINN RV Leveling Blocks Pack is a 12-pack in blue with two Velcro straps, built for single and dual wheels and stackable under jacks. All three use the same interlocking idea, so pick on pack size and whether straps are included.

How to Choose Interlocking Levelling Blocks in Sixty Seconds

Do I need blocks or a curved leveler?

It depends on how much correction you face and how often. Blocks are the flexible choice: you stack them under tires, stabilizer jacks, and tongue jacks, and they double as jack pads. A curved leveler like the CARMTEK Camper Leveler Kit is the fast choice — you drive up the curve and stop when the bubble says level, hitting any point between 1/2″ and 4″. The trade-off is that a leveler only works under a wheel, and on some dual axle trailers it may need trimming to fit between the tires. Blocks ask for setup time; a leveler limits you to wheel positions. Many full-timers carry both.

How high can I safely stack them?

Follow the number the seller prints, not what feels stable. Camco states 4 ½” as the ceiling on its FasTen sets, both the standard and the XL. Lynx gives you a different route: arrange six blocks 3-2-1 for a pyramid up to 3.5″ for leveling, or a straight stack up to 6.5″ for stabilizing. Those are two different jobs. A pyramid spreads the load under a tire; a tall straight stack is for holding a jack or a step steady. If your campsite needs more than the stated limit, move the trailer or use a ramp instead of adding blocks.

What should I check before I order?

Three things. First, the load rating — the numbers here range from 15,000 lbs on the BUNKER INDUST set to 40,000 lbs on the Lynx packs, so match it to your rig with room to spare. Second, what ships in the box: some sets include a cap top that takes tire contact and adds only 0.25″ of height, some include a bag, and some are bare blocks. Third, the block footprint. Standard blocks are 8.5″ square, Camco’s XL is 10 1/2″ square, and the 4×2 set is 17″ long for dual tires.

Frequently Asked Questions

How much weight can these blocks actually hold?

It varies widely, and the listing is your only source. Lynx states up to 40,000 lbs across its packs, which covers most travel trailers and motorhomes. CARMTEK rates its leveler kit for trailers up to 35,000 lbs and tires up to 32″ diameter. Always leave headroom between your loaded trailer weight and the stated rating.

Do I need to buy anything else to make these work?

Usually, yes — and it depends on the set. The Lynx Levelers 11 Pack includes a cap top and a nylon bag, so it’s ready to use. RVMATE and OULEME both ship top blocks and a bag. The Lynx Levelers 6 Pack is bare blocks with nothing else.

What wears out first on a leveling block?

The top surface where the tire contacts it. That’s why cap tops exist — RVMATE says its top covers avoid direct contact between tire and block body and reduce compression wear on the tread, and Lynx sells a cap that adds only 0.25″ to the stack. UV exposure is the other long-term factor; OULEME states its blocks use anti-UV aging additives.

Is the smallest set on this list enough for my trailer?

It can be, if your campsite is close to level. The Lynx Levelers 6 Pack gives you a 3-2-1 pyramid up to 3.5″ for leveling, or a straight stack up to 6.5″ for stabilizing a jack. It won’t cover a heavy rig on a real slope, and there’s no bag, cap, or chock in the box.

Closing

For most readers, the Lynx Levelers 11 Pack is the pick — a 40,000 lb rating, a cap top that protects the stack, and a bag to keep it all together. If you want to skip the stacking ritual, the CARMTEK Camper Leveler Kit gets you level in under five minutes with a lifetime warranty behind it. Before you order, measure your tire width and check the stack height limit on the listing, then confirm what is in the box. That’s the whole decision.
