The Reaper® 543 Cam delivers more power than the 525 cams without sacrificing low-end torque, giving a strong, usable midrange. ⚙️
Its extremely smooth cam lobe layout keeps the valve train quiet and produces the smoothest cruise power band available.
It is an excellent bolt-in camshaft for stock to mid 96" and 103" engines and also works well in 88" and 96" engines.
The cam improves starting, increases throttle response, and can improve fuel mileage.
It responds well to increased compression, performance exhaust, and a high-flow air cleaner. Performance valve springs are required on '99–'04 engines; performance pushrods and lifters are recommended but not required. Made in the USA. 🇺🇸
