Gear Drive.
The biggest bolt-in cam for huge horsepower & torque gains.
S&S measured on the dyno: 2023 Low Rider ST with HPT496 camshaft, Stealth air cleaner, Super Street exhaust, max HP 120.73 @ 5770 RPM & max 127.04 torque @ 3230 RPM. 2023 Low Rider ST All Stock: Max HP 91.2 @ 4680 RPM & max Torque 119.2 @ 2960 RPM.
Compatible with all stock components but requires free-breathing air filter & exhaust mufflers. With each cam change S&S recommends their 583903 Precision tappet assembly set. This camshaft & gear kit includes camshaft, drive gear and driven gear on camshaft. Includes all required bearings, O-rings and hardware. Gear drive cams provide improved valve timing accuracy and more mechanical sound, when compared to chain driven cams.

Note: For best performance it is, like with all performance cams, recommended to use a free breathing air cleaner and exhaust system.
