S&S .475 inch lift cam is a bolt-in replacement cam designed for riders with stock engines that want to eliminate the factory chain drive system, but are not necessarily looking for more power.
Includes 475G gear drive camshaft set with inner gears for 1999-2006 Harley-Davidson® big twin models (except Dyna®). For use with S&S oil pumps only.
Features and benefits include:
- Improves valve timing accuracy by eliminating timing chain lash
- No tensioner shoes to wear out or fail
- Can be used with stock springs
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
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.
