Have you tried cheap plastic chocks that slip, crack or require pounding? AFA Chock Blocks have an aggressive ribbed design that grips your tires fast to give you the confidence to park on any downhill grade - or to use with wheel ramps on slick garage floors without fear of crushing. Just kick ‘em in place and walk away… that’s it. Here’s what you get: - 4 Wheel Chocks (2 Pair) enough for front and back of 1 axel. - Nylon reinforced rubber that’s 2-times stronger than old rubber designs that rip and tear. - Chock Blocks that won't crack, chip, slip and slide like cheap plastic options. - Wheel chocks that stand up to sun, sand, snow, mud, dirt, dust, and ice. - A textured bottom and ribbed top that grips your tires without the need to hammer or pound them into place. As you check out the pictures you'll notice the compact design. At 8 x 3.5 inches, with a 4.5-inch height, your Chock Blocks are small enough to toss behind the seat, yet tall enough to stop any sized tire from rollback (even truck tires). Also, notice the beefy handles. Unlike cheap options with eyebolts (that rust and bend), this large handle is made for easy grabbing, with extra room to tie your Chock Blocks together using rope for quick pullouts.
