S&S 475G Gear Drive camshaft set for 1999-2006 Harley-Davidson® big twins (except 2006 HD® Dyna®). This cam is designed as a bolt in stock replacement cam for riders with stock 1999-2006 engines who are not necessarily looking for more power, but want to eliminate the stock cam drive chains.
Kit includes front and rear camshaft set with inner gears. This kit works great if you are replacing cams in an engine already equipped with S&S gear drive cams, order cams with inner gears and reuse the existing outer gears. Camshaft installation kit for appropriate model year is also recommended.
 

Can be used with stock springs.


Quick installation - reuse many stock components, a great way to increase performance at an affordable price.

Pinion shaft run-out must be checked before installing S&S® gear drive cams. A hydraulic press and other professional tools are required to install S&S gear drive cams. Additionally, material must be removed from the inner surface of the stock gearcover. The stock crankcase will require clearancing for S&S .625", .640", and .675" lift cams. S&S recommends that gear drive Camshafts be installed by a professional mechanic. New Camshaft bearings and a new gearcover gasket are required to complete Camshaft installation. Gear drive Camshafts for 1999-' 06 models require the use of ball bearing style cam bearing rather than the stock roller bearing. Roller bearings have more internal clearance which can cause excessive gear lash and increased noise. The correct parts are provided in S&S Camshaft Installation Kit, part #106-5896. Due to the inherent characteristics of gear drives, you may experience more valve train noise with gear driven cams. Oversized and undersized gears are available to help achieve correct gear lash. We have found that with 160 lb. of valve seat force, the S&S gear drive Camshafts will perform well up to 6200 rpm. If higher rpm is anticipated, valve springs that provide higher seat force should be used. S&S can do a special order cam. Contact your S&S Customer Service Representative for more information.
