These Wheel Chocks are bar-none the absolute best you can buy. They are BIG, forget the tiny OEM chocks that some vehicles come with these are amazing. They are ultra high quality and a must for any serious offroader / overlander.....and now a few words from the manufacturer; Offroad Trail Tools:

We incorporated many hours of engineering, design and testing into producing a true off road wheel chock. This is not a cheap imported unit sold at the big box stores or the discount auto parts places.

Safety is always the first priority. "Designed from the ground up". Rated at 7,000 lbs per axle set.

Anytime you use a jack, you should be using wheel chocks. Whether using that Hi-Lift or an O.E. jack to repair something. Whether it be changing a tire or fixing that flat, you should be using wheel chocks. Always use in pairs.
Anytime you're winching, where you need to be the anchor point, you should be using wheel chocks.
