Endurapro Plus. Damping Force Adjustable EnduraPro PLUS are high-performance OE-shape shock absorbers. Built to use with the vehicle's original (OE) spring and upper mount, their lower spring seat is shaped identical to the OE shock absorber. In addition to replacing worn or leaking OE dampers, these products are excellent to improve specs like ride quality or handling without changing your ride height. You can also use them with TEIN lowering springs. *By request/order.
