Chain Drive like stock. 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 kit includes cam, all required bearings, O-rings and hardware. Gear drive cams provide improved valve timing accuracy but more mechanical sound, when compared to chain driven cams. The additional mechanical sound is the reason why OEM runs chain driven cams.
