ROBLOCK RV Leveling Blocks 2-Pack Red — 4" Max Height, 35,000 lb Capacity with Chocks & Carry Bag

ROBLOCK RV Leveling Blocks are a lightweight, weather-resistant 2-pack leveling system with integrated chocks and anti-slip mats that lift and stabilize trailers up to a 35,000 lb gross vehicle weight.

If you need a fast, repeatable way to level a travel trailer, camper, or dual-axle RV at campsites or on uneven ground, this kit provides stacked plastic blocks, tire chocks and textured mats in a compact carry bag. The design accepts tires up to 32 inches and delivers incremental height from 1/2 inch to 4 inches without trimming or heavy lifting. Constructed from UV- and aging-resistant materials, these blocks are built to resist weather exposure while remaining lightweight for easier storage and transport than wooden solutions.

How do these blocks make leveling faster on uneven campsites?

The stepped block design lets you drive forward in small increments and build height precisely where you need it. Textured surfaces increase grip while chocks lock the stack to prevent rollback, so you can level in minutes without complex tools.

• Adjustable height increments from 1/2" to 4" for fine-tuning.
• Textured anti-slip tops improve tire traction during placement.
• Integrated chock slots accept included chocks to secure the wheel.
• Works with tires up to 32" diameter—no trimming needed.

Will these blocks support heavy trailers and all-weather use?

Yes — the ROBLOCK system is rated for a gross vehicle weight up to 35,000 pounds and made from UV- and aging-resistant polymer to withstand sun, rain and seasonal temperature swings. The materials resist cracking and deformation that shorten life on cheap leveling blocks.

• G.V.W. capacity: 35,000 lbs—suitable for many travel trailers and campers.
• Durable polymer resists UV exposure and weather-related aging.
• Rubber pads under the blocks help stabilize on softer ground.
• Lightweight construction reduces carry and storage burden compared to wood.

What comes in the kit and how do I store it between trips?

The package includes two stackable leveling blocks, complementary chocks, anti-slip mats and a compact carry bag so everything stays organized. After use the blocks nest together and fit back into the included bag, saving space in storage compartments or a small trunk.

• Two stackable leveling blocks for building height as needed.
• Two matching tire chocks that slide into the gear mesh slots for locking.
• Anti-slip rubber pads for added stability on soft or uneven surfaces.
• Durable carry bag for compact storage and easy transport.

How simple is setup and compatibility with different tire sizes?

Setup requires only driving forward onto the blocks until the trailer achieves the desired level. The profile fits tires up to 32 inches diameter and is designed so most lightweight campers and dual-axle trailers can use the blocks without trimming or modification.

• Drive-on design enables quick height gain without jacks or tools.
• Compatible with tire diameters up to 32" for wide vehicle coverage.
• No trimming required for most campers and dual-axle trailers.
• Gradual stacking avoids sudden lifts that can stress equipment.

Who this is for: Choose the ROBLOCK RV Leveling Blocks if you frequently camp in uneven sites, want a lighter and more portable alternative to wood, or need a dependable leveling solution compatible with most travel trailers and dual-axle campers. It’s suited for solo campers, families, and road-trippers who want quick setup, reliable traction, and compact storage without sacrificing weather-resistant durability.
