This subframe is designed to fit along the floor of the vehicle without cutting the uni-body. The subframe is made of 1.625 dom roll cage tubing, MIG welded and gig fitted, to ensure proper fit. The front box slides over the front clip and sandwiches between the special Interloc body mount bushings supplied in the kit The very back of the subframe welds to the rear frame rail that goes over the differential (not the spring mount area). This subframe will clear traction devises without interference. The subframe connectors are a good investment for any application that has horsepower.
