We are a auto/diesel shop located in North Bend, OH. Holderdown Performance was established March of 2009 and we can handle your truck servicing all the way up to building a full competition truck for sled pulling or drag racing. We do specialize in Power Strokes motors and the transmissions that back them. We also are a OEM and performance parts supplier.  We have no problem working on and/or selling products for Cummins and Duramax. We also cover gas repair and performance!
