These new heavy/duty front tow hooks attach to the strongest, forward most point of the 911's front suspension - the front of the a-arm. The tow hooks are bolted down by the same three large bolts that secure the front a-arm to the unibody, and they've been specifically designed as skid plates that will keep your 911 protected when traversing steep driveways or speed bumps. Rennline's tow hooks are made of stainless and powder coated red, so they are easily visible to tow truck operators. Installation of tow hooks will not affect alignment settings. All new hardware is included with kit.
