ROBLOCK 6-Inch Trailer Jack Blocks (4-Pack) with Bag for RVs and Trailers
Product description
What it is and what problem it solves
These ROBLOCK 6"H blocks come in a 4-pack with a handy carrying bag. Built from a high-performance polymer with anti-UV aging additives, they’re designed to resist dirt, grime, and oil for long, rugged use. They’re intended to eliminate nearly all movement and sway in parked RVs and trailers by providing a stable base for tongue jacks and stabilizers.
Why it stands out on paper
The blocks are rated with a GVW of 40000 lbs per block, suggesting they’re meant to handle a wide range of tongue jack feet, wheel jacks, 9-inch round 5th wheel hydraulic jack feet, and scissor stabilizers. The stackable design lets you tailor the height to uneven surfaces, helping you achieve level footing without dragging out unstable manual shims.
What works well in day-to-day use
The product ships with a storage bag and features a side hole and rope for easy carry, which helps when you’re moving between campsites or stashing the blocks in a tight storage area. The size is roughly 6" tall with a footprint of about 11.5" x 11.5", which gives a stable base without taking up excessive space.
considerations and potential limits
On very uneven terrain or highly irregular surfaces, you may still need to assess the ground condition to ensure the blocks contact points are stable. While the polymer is robust, it’s not a replacement for solid leveling in extreme conditions. If you prioritize ultra-lightweight gear, these blocks offer portability, but you’ll want to confirm your specific tongue jack foot or stabilizer matches the footprint of the blocks.
Who it’s for
This set is a good fit if you own a travel trailer, camper, or RV with a tongue jack foot, a wheel jack, or a hydraulic stabilizer and want a straightforward leveling solution that travels well. It’s especially appealing for users who appreciate a compact storage option and a system that reduces movement at the foot of the tongue.
Who might want to skip it
If you rarely encounter uneven ground or require alternative leveling methods beyond a simple block system, you may find this setup more than you need. It’s also worth noting that extreme off-road setups or non-standard stabilizers might not align perfectly with the block’s footprint.
When it makes sense to buy
Consider this four-pack when you’re regularly setting up on varied surfaces and need a predictable, reusable base that minimizes movement. The included bag and the stackable height feature add practical value for frequent campers who want a compact, organized kit.
What to check before purchasing
- Confirm your tongue jack foot or stabilizer feet are compatible with the 11.5" x 11.5" footprint.
- Consider your typical campsite terrain and whether the height range covers the adjustments you usually require.
- Ensure you’ll use the carrying bag for transport and storage convenience.
Practical usage scenario
Imagine pulling into a campground with an uneven lot. You place the four blocks under the tongue jack feet, stack to the needed height, and secure the bag nearby. The trailer stabilizes quickly, reducing sway as you level the camper, load supplies, and hook up utilities.
In-context comparison
If you’re deciding between a simple wedge approach and these stackable blocks, the blocks offer adjustability and portability without requiring assembly tools. They sit between basic shims and more elaborate leveling kits, aiming for a balance of ease of use and capability.
Final decision
Final verdict
Is it worth it? If you value portable, adjustable leveling that works with a variety of jacks and stabilizers, this 4-pack with bag is a practical option worth considering. It may not replace a more heavy-duty leveling system in extreme setups, but for typical travel trailer and RV use, it provides a sensible, reusable solution.
