Manley Performance - Forged Valves, Pistons, Rods, Springs, & More
Founded in 1966 by Hank Manley in New Jersey, Manley Performance has become a benchmark in high-performance engine components for racing and street applications. Known for pioneering stainless steel valvetrain hardware, forged 2618 alloy Platinum Series pistons, H- and I‑beam connecting rods, high-flow spindle crankshafts, and valvetrain systems, they consistently push engineering boundaries.
From humble beginnings—packing valves in a garage and selling pipe dream-injected T-Birds—to state-of-the-art manufacturing in Lakewood, NJ, and Orange, CA, Manley invests heavily in CNC machining, strict QC, and close tolerances: “extreme tension to detail in our QC”. Their products have powered legends like Don Garlits, Bill Jenkins, and Jungle Jim Liberman, and OEM programs such as Ford’s SVT Cobra rods.
Now part of Race Winning Brands, Manley stays committed to “manufacturing the finest internal engine components at competitive prices” with full support for modern platforms (LS, Evo, WRX, Mustang, domestic V8s). Whether you’re building a torque-heavy street cruiser or a pro-level race engine, Manley Performance delivers unrivaled precision, strength, and reliability.
