Perfect replacement. My original rear tensioner was lazy and only held 2% when used on the rear brakes. So if I pedaled the E-Brake it would bottom, and if I put the truck in Drive with the pedal depressed, the truck would roll a way. With this new item I can put the truck in drive and press the brake pedal and the truck won't even roll up a hill so it works but if that part is fishy I would check the rest of your brake cables as well. A NOTICE. If you go to the state inspection, it will fail if the rear brakes don't hold.
