Designed to deliver strong mid-range power while preserving low-end torque, the Reaper® 543 cam offers more power than the 525 cams with an exceptionally smooth cruise band. 🔧
The extremely smooth lobe layout maintains a quiet valve train and responds well to increased compression, performance exhaust, and a high-flow air cleaner. 🇺🇸
Easy starting, improved throttle response and better fuel mileage make it an excellent bolt-in cam for stock to mid 96" and 103" engines; it also works well in 88" and 96" engines.
Requires performance valve springs on '99-'04 engines; performance lifters are recommended but not required. Will work with factory pushrods on engines with factory stack up.
