Turn big-inch engines into a true horsepower plant with the 590G Gear Drive Camshaft Kit. 🏍️🔧 This all-out performance cam is built for monster bores and ported heads and is not recommended for stock-bore engines. The gear drive design improves cam timing accuracy and eliminates the stock cam chain for a more precise, durable setup.
The kit includes outer drive gears, bearings, o-rings, and hardware for installation. For touring models, a heavy duty valve spring kit is required to control the increased lift and duration. This cam demands Quikee adjustable pushrods with cover keepers for correct operation. Tappets should be replaced whenever the cam is changed; S&S recommends the Precision Tappet set without the HL2T Kit and Tappet Cuffs for M8 models.
Intended for 124” and larger engines, this cam is for riders and builders chasing maximum horsepower. Made in the USA. 🇺🇸
