Frequently Asked Questions

What comes in the kit?

Camshaft, gear drive components, all bearings, o-rings, and mounting hardware. Adjustable pushrods and valve springs must be purchased separately.

Do I need any additional parts to install this?

Yes — you will need adjustable pushrods and heavy duty valve springs, which are not included in this kit.

Will this fit my stock 107 displacement Touring?

No — the 550G profile is designed for 114 cubic inch and larger engines. A smaller displacement engine requires a different cam profile.

How does gear drive compare to the factory chain drive?

Gear drive provides more precise valve timing, eliminates chain stretch and wear, and runs quieter than the factory tensioner system.

Is this made in the USA?

Yes — S&S Cycle manufactures this camshaft kit in the USA.
