Outback Armour extended bump stops are designed to provide protection for the shock absorbers and coils springs in the event of sudden and substantial impacts such as holes, logs, rocks or other unseen objects and obstacles. The progressive rate rubber absorbs impacts and slows down the travel on compression to provide a softer landing. The result is a smoother ride, improved cornering and significantly reduced chance of vehicle damage or suspension component damage. Bump stops can be installed with or without the optional steel cups and spacer washers to fine tune the compression rate on your vehicle to suit weight of accessories and personal preferences.
