I was particularly impressed by the lifetime warranty that comes with these levelers, offering free replacement or refund if any issues arise. That kind of confidence from the manufacturer is a real win.Anti-Slip System: One of the standout features of the BOYISEN RV Leveling Blocks is their double anti-slip system. The curved levelers are equipped with grips, and the chocks have notches on their surface, all working together to keep your RV securely in place.

They're compact and come with a carrying bag, making it easy to keep them organized and ready for your next adventure.I purchased an extra set since I desperately needed this larger height for more extreme leveling situations.

The 3inch gap isn't true will half to trim to make fit between the two wheels other than that there not bad

will work well and can now get rid of wood blocks

Nice product, doesn’t fit on smaller tandem axel trailers. Measure before purchase. I will be ordering g the smaller ones.

I bought this large RV Leveling Block Ramp Kit specifically because of its capacity to lift 6” rather than the 4” most other ramps offer. The ad on Amazon specifically states that they are “suitable for tight dual axles without trimming” but it does not state what “tight” is. I have 7” between my axels and the ramp needs to be forced between the wheels. Although the ramp can be wedged in, I can see I will have to physically jack the wheel off the ramp to get it back out unless I trim the ramp. This is a real disappointment after spending nearly $100 to get these large leveling blocks.

4 stars.We had previously tried the 4" version blocks of this style, with mixed results. In that case if you drove the vehicle far enough ahead to aim for the maximum height (and the 4" max is really overstating its capability a little), then getting down off the blocks was tricky if the rear blocks had been jammed in place. If the rear chock blocks are jammed you have to drive forward a little to get them out, and if you were already at full height you will fall off the front edge of the block. We chose to try to get out of this situation by backing over the rear chocks, and one got crushed in the process.This 6" set is a much more useful size, but I wouldn't expect to get the full 6" height unless you can stop on a dime traveling forward. Even then it is probably more practical to count on a little less maximum height. The way we are using these now is to drive up on the curved ramps to the correct height and slam on the brakes, and try to engage the parking brake without rolling back down. Then we put the rear chocks in place just touching the ramps without jamming them in, so they will act as a safety chock only if the vehicle should roll backward. This way when it's time to leave we can usually kick the rear chock loose without having to try to unlock the parking brake and drive a little forward.This 6" size is much more useful than the 4" set, and we find these easier to use than the older lego-style riser blocks. The package is getting a little large to haul however. The carrying bag is 13" x 17" x 7", but at least this time the bag is roomier and easier to pack back up than the 4" set.Down rated by one star only because the price seems high for molded plastic parts that we have demonstrated (on the earlier 4" set) can be crushed if you drive off them the wrong way. Properly used they seem to be strong enough for our 26-foot RV however.

The leveling blocks are made from what feels like a very strong plastic material. My trailer tires on my 5th wheel rolled onto the leveling blocks just fine and I was able to place the holding block underneath it. But when I went to use my rubber mallet to make sure the black holding block was secure under the tire, as well I noticed that the grooves that are on the bottom side of the orange block kept the black block from sliding completely under it. I was not able to wiggle the black block with my hand, showing me that it is very secure under the orange block. It just doesn't look like it from a visual perspective. Did the leveling blocks lift my wheels up? Yes they did. The tires aren't going to move as I have them chocked. And as a "leveling system" I do think that these blocks feel extremely sturdy. As this was my first attempt at using them trying to get the rubber mat that they sit on under both blocks appears to be a work in progress. All and all a nice option to help you level your camper or 5th wheel.
