We sell all original equipment, not reproductions. Shocks are cleaned to the bare metal, the housings are rebushed with bronze bushings, and shafts are reground. To aid with dirt and water exclusion, highest quality Buna-N nitrile seals are used, which will outlast the originals. Valving is properly calibrated for correct jounce and rebound specs. Shocks come painted with a gunmetal grey primer, filled with fluid, and ready for installation. If you return your old shock to us, we will refund a $100 core deposit back to you. Just pack your old shock in our box, include a copy of your invoice and write core refund on it. Send it back to us at the address on the label. Please see our other listings to buy this item as a set Apple Hydraulics - The Industry leader in rebuilt lever shock absorbers.
