The B8 Billet Aluminum Rear Spring Perch replaces the OEM rubber top perch. Rubber acts as a spring with a mystery spring rate, leading to unwanted oscillations that reduce the ability of your suspension to keep the wheels planted firmly on the pavement.

As with all of our products, weight is always a concern. We’ve designed this specifically to keep the weight as low as possible. Weighing in at just 7.6 oz, it gains no weight over the OEM part.
