S&S 510G cams are designed as a bolt in cam for 88, 95 and 96 inch engines with compression ratios below 9.7:1. Intended primarily for stock heads that have not been ported. Includes 510G gear drive camshaft set with inner gears. For 2006 Harley-Davidson® Dyna® and 2007-Up big twin models with stock oil pumps.
Can be used woth stock valve springs.
Fuel injection tuning required.
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 may require clearancing
for S&S .625", .640", and .675" lift cams. S&S recommends that gear drive
cams be installed by a professional mechanic.
Due to the inheraent 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 cams 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.
