S&S Cycle Complete Gear Drive 509G Camshaft Kit

• The S&S Camshaft Gear Drive Kit increases valve timing accuracy in 1999-2006 Twin Cam 88 engines by eliminating timing chain lash and the loosely fit stock cam gears

• This is accomplished by replacing the stock cam drive sprockets and chain with light press fit S&S gears

• Because the chain, chain guides, and tensioner are eliminated, there is no longer a possibility for these parts to fail and damage other parts

• The S&S Camshaft Gear Drive Kit reverses the rear cam’s direction of rotation, providing additional operating clearance between cam lobes

• As a result, higher cam lifts are possible with the gear drive kit

• Bolt in Camshaft set for 1999-06 Twin Cam, 180 psi cranking compression, no need for compression releases

• RPM range from idle to 4500

• Great bolt in torque
