The P2R OE+ Billet Camshafts are the ultimate solution for restoring and enhancing the performance of your J37A2 engine. Designed as a true drop-in replacement for the 2009–2012 Acura RL 3.7L, these camshafts deliver proven gains of 5+ horsepower on a stock engine—no tuning or aftermarket valvetrain required.

Unlike the OEM camshafts, which are prone to premature lobe wear due to hardening issues, our billet camshafts are precision-machined, properly hardened, and built to last. They're ideal for anyone dealing with worn factory lobes or looking to proactively upgrade before failure occurs.

P2R is the exclusive source for these billet camshafts—developed in-house and offered only through us. Trusted by the community for years, these are a proven solution.
