Best pick for dual-axle trailers
The Tri-Lynx Lynx Levelers / Lynx Levelers 11-Pack with Level Top is the safest all-around starting point for many tandem trailers because it is a true stackable block system, carries a 40,000-pound rating, and is designed for single wheels, dual wheels, tandem axles, and approved jack-foot support. Tri-Lynx also recommends stacking no higher than five inches.
Why this stackable system fits most tandem trailer setups
Stackable blocks fit best when the dual-axle spacing is tight or the campsite slope changes from site to site. You can add only the height you need, which helps on paved pads, packed dirt, or firmer gravel where a ramp may shift before it settles.
A common first-timer mistake is buying a curved leveler because it looks faster, then finding that the dual tires do not leave enough room for the ramp body and landing edge. A block stack avoids that problem when the wheel area is cramped.
Where the 40,000-pound rating and five-inch stack limit matter
The rating matters because tandem trailers load both axles during leveling. The five-inch stack limit matters because over-stacking can reduce stability and make the wheel stack harder to place squarely on the ground. If you need more than five inches, choose a different site or a different leveling method instead of pushing the stack past the stated limit.

Camco FasTen RV leveling Blocks
The Camco FasTen RV Leveling Blocks are a straightforward 10-pack interlocking block set with an integrated T-handle for storage. That makes them a practical choice when you want a neat block stack and do not need a ramp profile.
Use them when your trailer needs a modest lift and your dual-axle layout leaves enough room for a square block stack under the wheel path. They suit owners who value simple stacking over speed.
Camco Heavy-Duty Leveling blocks
The Camco Heavy-Duty Leveling Blocks come as a 10-pack, measure 8.5 by 8.5 by 1.5 inches, and add about one inch per block. That makes them easier to plan with when you need a known lift increment for a dual-wheel or tandem-axle setup.
These blocks work best when you already know roughly how many inches of lift the site needs. If the site requires only a small correction, a shorter stack keeps the setup lower and easier to seat on firm ground.
Beech Lane Camper Leveler 2-Pack
The Beech Lane Camper Leveler 2-Pack is a curved ramp-style leveler rated to 35,000 pounds and supports up to 4 inches of adjustment. That makes it a fast side-to-side leveling option when the wheel spacing and wheel well layout give the ramp enough room to fit.
Beech Lane also includes chocks and grip mats. On some tight dual-axle layouts, trimming may be needed to clear the spacing, so this is not the first choice for every tandem trailer.
Andersen Hitches Camper Levelers
The Andersen Hitches Camper Levelers are sold as a 2-pack and raise from 0.5 to 4 inches. They are commonly used for faster side-to-side leveling when you want to drive onto a curved surface instead of stacking blocks.
They can be awkward on some dual-wheel setups with limited space. If the tires sit very close together or the wheel area is narrow, a stackable block often fits with less guesswork.
Stackable blocks for most tandem trailers
Stackable blocks are the better default when tire spacing is tight, the campsite surface is uneven, or you want exact control over lift height. They also work better when you are not sure how much correction the site will need.
Camco FasTen RV leveling blocks: the FasTen set
The FasTen set is a clean choice for campers who want a familiar block stack without moving to a curved ramp. Its 10-pack format gives you room to adjust lift height, but you still need to confirm that the wheel area can accept a stacked footprint.
Camco Heavy-Duty Leveling Blocks: because each block adds about
Because each block adds about one inch, these are easy to count out for a target lift. That helps on sites where you can measure the low side before parking and want a predictable stack rather than a ramp profile.
RVMATE 12 pack RV leveling blocks
The RVMATE 12 Pack RV Leveling Blocks are a 12-piece kit with 8.5 by 8.5 by 1.5-inch blocks and top blocks for stacking flexibility. This gives you more combinations than a smaller kit when the trailer needs a custom lift height.
Choose this style when you want more stacking choices and your trailer layout gives you enough room for a block base under the tire path.
Tri-Lynx Lynx Levelers / Lynx Levelers 11-Pack with Level Top
Tri-Lynx is the pick when you want a block system that is explicitly positioned for single wheels, dual wheels, tandem axles, and approved jack-foot support. The five-inch stack limit is the key constraint, so this is a fit-first choice rather than a “pile on more blocks” choice.
Curved ramps for faster side-to-side leveling
Curved ramp-style levelers are the better choice when the wheel spacing leaves room for the ramp body and you want quicker setup than a block stack can offer. They are popular for side-to-side leveling, but they are less forgiving on tight dual-wheel layouts.
Beech Lane Camper Leveler 2-Pack: beech Lane is the curved-ramp
Beech Lane is the curved-ramp pick when you want up to 4 inches of adjustment and a kit that includes chocks and grip mats. The 35,000-pound rating gives a clear load figure, but the real purchase decision is still fit at the tire gap.
Andersen hitches camper levelers: andersen’s 0.5-inch
Andersen’s 0.5-inch to 4-inch range makes it useful when you need a broad adjustment window without stacking multiple blocks. The tradeoff is fit. On some dual-wheel setups, the ramp shape and limited gap make installation harder than a block stack.
OULEME dual-axle leveling system
The OULEME dual-axle leveling system is a 2-pack curved leveler rated to support up to 35,000 pounds and lift from 1/2 inch to 4 inches. It also lists tires up to 32 inches in diameter, which makes tire size part of the buying decision.
This is a sensible ramp-style option when your trailer’s tire diameter matches the listing and the dual-axle spacing leaves enough room for the ramp shape to work cleanly.
When a curved design may be harder to fit on dual-wheel setups
Curved levelers can fail when the gap between the tires is too narrow, when the ramp body hits the inner tire, or when the site surface is soft enough that the ramp sinks before the trailer settles. In those cases, a smaller block stack often fits better.
Picture a tandem trailer on a slightly crowned gravel pad. The curb side needs only a small lift, but the tire gap is tight. A curved ramp may not seat cleanly, while a block stack can be adjusted one layer at a time.
Dual-Axle Fit Checklist
| Tire spacing | Tire diameter | Required lift | Campsite surface | Preferred block style | Red-flag failure cases |
|---|---|---|---|---|---|
| Wide enough for the full ramp body | Matches the product’s stated tire range | 0.5 to 4 inches | Paved pad or firm gravel | Curved ramp | Ramp body touches the inner tire; soft ground lets the ramp sink |
| Tight dual-axle gap | No published tire range or larger than the stated range | 1 to 5 inches | Packed dirt or gravel with uneven spots | Stackable block | Ramp will not clear the gap; one axle lifts before the other settles |
| Moderate gap, room for a short stack | Standard travel-trailer tire size | About one inch per layer | Firm, level pad with minor slope | Stackable block | Over-stacking past the product limit; unstable stack on soft soil |
| Very tight spacing or limited clearance | Unknown or near the upper limit of the ramp listing | Small correction only | Any surface that shifts under load | Stabilizer-only companion after leveling | Using a stabilizer as a leveling tool; tire or frame twist from bad fit |
Decision rule: choose stackable blocks when tire spacing is tight or the ground is uneven; choose curved ramps when the wheel gap and tire diameter match the product listing and you want faster setup; choose a stabilizer-only companion like BAL X-Chock only after the trailer is already level.
How to choose the right leveler
Start with the wheel layout. If the dual tires sit close together, a block stack usually gives you fewer fit problems. If the wheel area is open enough for a ramp and the tire diameter matches the listing, a curved leveler can save time.
Match the product to tire spacing and wheel layout
Measure the gap you have under the tire path and compare it with the ramp body, not just the advertised lift range. A leveler can have the right height range and still fail if the shape does not clear the dual tires.
Choose the lift range that matches your site
Use the smallest lift that levels the trailer. If a site needs only a minor correction, a stackable block set keeps the setup simple. If the site needs a larger side-to-side correction, a curved ramp with a 4-inch range can be the better match, provided the tires and spacing fit it.
Pick the surface grip that suits gravel, dirt, or pavement
Soft gravel and dirt can change how a leveler sits. On those surfaces, a broader base and careful placement matter more than brand name. A leveler that works on a paved pad may behave differently on a crowned or soft site.
Check storage, install speed, and weight rating
For many owners, the decision is simple: blocks store more easily, ramps install faster when they fit, and the weight rating must match the trailer. Follow the trailer and product manuals, never work under a vehicle held only by a jack, and keep items out of airbag zones and the driver’s view.
Say your trailer needs just over 2 inches of correction on the low side. A stackable block set lets you build that height in steps. If the same trailer sits on a tight dual-wheel layout, the block stack is more likely to fit than a curved ramp that needs more clearance.
Do you need chocks and stabilizers too?
Yes. Wheel chocks come before unhitching, and stabilizers come after leveling. BAL X-Chock is for tandem-axle stabilization after the trailer is already level; it is not a leveling block substitute.
BAL X-Chock for tandem-axle stabilization after leveling
X-chocks reduce fore-aft rock between tandem tires once the trailer is level. They help with motion control, but they do not raise a low side or replace a wheel-leveling block. Use them as a companion, not as the primary leveling tool.
Why wheel chocks come before unhitching
Wheel chocks help prevent unwanted movement while you are setting the trailer. Place them before you unhitch, then level the trailer, then add stabilizers if needed. That sequence keeps leveling and stabilization separate.
Why stabilizers do not replace leveling blocks
Stabilizers support movement control. They do not correct side-to-side pitch. If you try to use a stabilizer foot or X-chock as a leveling device, you risk an incorrect setup and a trailer that still sits out of level.
Frequently asked questions
What are the best RV leveling blocks for dual axle trailers?
The best choice depends on fit, not brand name alone. For many tandem trailers, the Tri-Lynx Lynx Levelers / Lynx Levelers 11-Pack with Level Top is the safest default because it is a stackable system with a 40,000-pound rating and a five-inch stack limit. Tight spacing often favors blocks over ramps.
Are stackable blocks or curved levelers better for tandem axles?
Stackable blocks are better when tire spacing is tight, the surface is uneven, or you need exact height control. Curved levelers are better when the wheel gap and tire diameter give the ramp enough room and you want faster side-to-side leveling. The right answer depends on fit.
How many leveling blocks do I need for a dual axle trailer?
There is no single count for every trailer. You need enough blocks to reach the required lift without exceeding the product’s limit. Tri-Lynx recommends stacking no higher than five inches, while Camco Heavy-Duty Leveling Blocks add about one inch per block, which makes planning easier.
Can RV leveling blocks be used under dual wheels?
Yes, if the block system is designed for that layout and the wheel spacing allows a stable stack. Tri-Lynx states that its system works for dual wheels and tandem axles. Always confirm that the wheel path and ground conditions support the stack without forcing one tire off the ground.
Do camper levelers fit between dual tires?
Sometimes, but not always. Curved ramps need enough room for the ramp body and the tire path, and some dual-wheel setups are too tight. Beech Lane notes that trimming may be needed for tight dual-axle spacing, which is a clear sign that fit can be a problem.
What is the difference between leveling blocks and X-chocks?
Leveling blocks raise one side of the trailer to correct side-to-side pitch. BAL X-Chock does something different: it reduces fore-aft rock between tandem tires after the trailer is already level. They solve different problems and should not be used interchangeably.
Can leveling blocks be used under stabilizer jacks?
Only if the product listing and the trailer manual allow it. Tri-Lynx lists approved jack-foot support, but that does not mean every leveling block is suitable under every jack. Follow the manual for your trailer and the hardware instructions for the exact support point.
