Step 2 Cams and Pushrods
Gain Up to hp Over Stock!*Once you've let your engine breathe with a high flowing S&S intake and exhaust system in Step 1, it's time to take the next step. Step 2 of the S&S 4-Step Performance Program is to replace your stock camshaft with an S&S bolt-in performance cam.
S&S bolt-in cams make it easy to get some serious gains in horsepower and torque. S&S offers a complete line of bolt-in cams for most models and applications. Choose from stock chain drive style, or upgrade to S&S gear drive cams for the ultimate in valve train control.
We highly recommend S&S Easy Start cams, which feature centrifugally operated compression releases that are not only convenient, automatic, and foolproof, but reduce wear and tear on your battery and starter. No more dead battery. Get something started!
Upgrading your cams requires pushrod removal. S&S recommends installing S&S Quickee pushrods. They are fully adjustable, and allow for quick removal for other future upgrades or tappet replacement – they pay for themselves by saving time on labor.
*Horsepower gains require components in previous steps.
Keep your Harley-Davidson® motorcycle real deal with American made S&S intake and exhaust!
1999-2004 engines with stock valve springs can accept cams of up to .510" lift, while 2005 and later engines can accept cams of up to .585" lift. The earlier engines can be upgraded with S&S high lift valve springs to run higher lift cams. Step 2 requires carburetor or EFI recalibration. For 2001 and later Harley-Davidson® models with single bore Delphi EFI systems, S&S recommends the Dynojet® Power Vision® tuner. See page 20 for details.
