Suncore's rear complete struts replace the rear suspension in both the left and right sides using loaded struts with coil springs compressed around the base. Built into the strut is the top mount, bearing plate, spring seat, dust boot, isolators, and bumper. Both units will come ready to install meaning all you have to do is remove the old suspension components and install the new complete strut in its place. With no need to assemble you save time and effort and the strut pair is a fraction of dealership prices, meaning you save money as well.
