Adjustable - TUFF BLOCKS have adjustable trailer stops. Simply unscrew and rotate the stop. When you receive the block it will be screwed in for a 9 inch stop. If you need a 6 inch stop, unscrew and screw it back in with the stops out at the corners of the block. If you need the block to be flat on top, turn the stops over and screw them in. Stability – TUFF BLOCK jack stands measure 12”L X 8.5” W X 6” H. This increased large footprint reduces sinking in soft soil and protects the jack from ground damage. By adding height under your jacks, you can reduce the jack extension which reduces sway for a safer experience. If you need additional height, they can be stacked or used with our Tuff Block XL Leveler Pads!
