The HiPoTek engine torque strap prevents unwanted side-to-side movement of the engine due to the extra load from higher horsepower applications, racing, and aggressive driving. It can prevent broken parts such as motor mounts, and transmission mounts.  It will improve your off-the-line and road handling performance.  This engine torque strap works as a turn-buckle with rod-ends at each end.  Turn it one way, and you can add preload at the track.  Turn it the other way, and you can relax it for every day driving.
