RELIANCER 2 Pack Wheel Chocks Heavy Duty Extra Large Industrial Rubber Wheel Chock Blocks w/Handle Reflective Strips for Travel Trailer Hauler Truck Fire Truck Commercial Vehicle RV 10" x 6" x 7.3"

I like the size of these and the fit. I accidentally ran over my cheap plastic ones and needed to replace. I added ropes so I could pull out and pick up easily. The reflective strips on the edge are a bonus. They are heavy and strong.

Great heavy rubber tire chocks. Stay in place, don't slide on wet pavement. Also use as stability for other objects ln bed of truck: water jugs, fuel cans etc. to minimize movement.

We needed a sturdier chock for our 5th wheel travel trailer. Others were too lightweight and not dependable. These are exactly what we needed. Only gave 3 stars for being ‘light weight’ because they are not light weight - but that’s the point! They are thicker and heavier and get the job done when lighter ones do not. A lot of reviews mention an odor. It’s just the rubber. Leave it outside for a couple of days after opening and there is no problem.

They work great. My boat is 2500lbs on a steep incline in the driveway and it hasn’t budged even through big storms. The smell is atrocious though.

Perfect for my Truck. I have 1-ton Chevy Pickup Truck with 16 inch tires and these are PERFECT I am going to order a second set for my motorhome. On my steep driveway, they hold and don't skid backward as the plastic ones do. They grip and wedge in really well and they are large. I also ordered these: "MaxxHaul 2 pack 70472 Solid Rubber Heavy Duty Black Wheel Chock, 8" Long x 4" Wide x 6" high-2 Pack, 2 pack" (These are not the ones I am reviewing here) and they are good for mids size car and made well but are no comparison to these Relaincers. These are truly Heavy Duty. Great quality and a great price.

I liked the chocks because they were large enough for the semi trailer.I need chocks to hold the trailer wheels so I can slide the trailer when the trailer brakes don't hold.

Wow these things smell awful. They're great wheel chocks. Chunky and seem to be well made, but smell strongly like asphalt. The inside of my van stunk for an hour after putting them inside for a few minutes.

Possibly overkill, but I bought these for our Honda Accord. Last month, it slid halfway down the driveway even though we’d shoveled away the snow. There was just enough ice and just enough of an incline. Needless to say, having a car slid out into traffic isn’t a joke. I’ve used these once and I already notice that a.) there was enough ice for the car to slide, and b.) these worked. They’re heavier than I thought and there is a slight odor to them, but the handles are great and I just put them in the trunk and go. The quality seems excellent.
