The Quality Stainless Products Strut Compressor, No. DB-8000-XL, is designed to handle strut assemblies including 4 by 4 aftermarket lift kits. The four-point spring contact system assures even pressure distribution during compression and the four individually adjustable extra strong clamps provide an ideal grip. A safety microswitch prevents operating if drop down guard is not correctly positioned. In addition, the lower support plate and the foot operated pedal allow both hands to be free during the repair/assembly process. Approved equipment by many OEM programs.
