Increase your bike's efficiency and durability

The new Screamin’ Eagle Hydraulic Cam Chain Tensioner and High-Flow Oil Pump Upgrade Kit (P/N 25284-11, $499.95) from Harley-Davidson Genuine Motor Accessories updates the cam chain tensioner of a Twin Cam 88 engine to the latest hydraulic design featured on Twin Cam 96 and 103 engines. The hydraulic cam chain tensioner is significantly more durable than the original spring-loaded tensioner and is an ideal addition to an engine modified for improved performance. 2002-2006 models utilize a Twin Cam 96 single-row front roller chain and sprocket, while 1999-2001 models use the Original Equipment front silent chain and sprocket to retain the cam position sensor function.

Each kit includes an improved Screamin’ Eagle High-Flow Oil Pump that provides increased oil pressure at high operating temperatures. This kit increases the oil supply by 23% and scavenging by 50% when compared to the 1999-2005 Original Equipment oil pump, and it reduces the operating temperature of bearings to improve bearing life.

Fits 1999-2005 Dyna models, 2000-2006 Softail  models and 1999-2006 Touring models. Installation requires separate purchase of Spacer Kit P/N 25285-08, Cam Service Kit P/N 17045-99D and Drive Gear Retention Kit P/N 25533-99A.
