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 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 foot-operated pedal allow both hands to be free during the repair/assembly process. Approved equipment by many OEM programs.
