Get the Horsepower you want!

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.

For you Milwaukee-Eight riders, we also recommend upgrading your factory tappet guides which are constructed of plastic and are at risk for allowing the tappets to twist under heavy stress. S&S Tappet Cuffs capture the tappets without impacting vertical motion and keeping them perfectly aligned, even in high stress, high RPM situations.


Bolt-In More Power!

S&S® offers a variety of cam grinds for Milwaukee-Eight & Big Twin engines in both chain drive and gear drive versions. Cams that exceed the limits of the stock valve springs require the use of special high lift springs. Due to the high lift of these cams, S&S adjustable pushrods are recommended. Not all grinds are available in the chain drive version. To get the best performance from a performance cam installation, a high flow intake and exhaust system is also recommended.
