Manley Performance: Decades of Race-Proven Engine Excellence

Manley Performance has been a cornerstone of high-performance engine building since March 1966, when founder Hank Manley launched the company out of Bloomfield, New Jersey. A passionate gearhead who had been racing on the streets of New Jersey since age seventeen, Hank built the brand on a simple but demanding philosophy: manufacture the finest quality internal engine components at competitive prices. What started as a small operation with a mimeographed catalog has grown into one of the most respected names in the performance aftermarket, with state-of-the-art manufacturing facilities in Lakewood, New Jersey and Orange, California.

From the earliest days, Manley supplied some of the most legendary figures in motorsports history. Throughout the 1970s, icons like Don Garlits, Bill Jenkins, Joe Mondello, and "Jungle Jim" Liberman were turning to Manley components to build winning engines. That legacy of race-proven performance never faded — it evolved. Today, Manley serves not only grassroots racers and professional race teams worldwide but also acts as an OEM supplier, having earned recognition from major automotive manufacturers including Ford.

The brand's product line covers virtually every critical internal engine component a performance builder needs. Engine connecting rods remain one of Manley's signature product lines, with their Turbo Tuff and H-Beam series offering exceptional strength for boosted and high-horsepower applications. Equally important are Manley's engine valve springs, with the proprietary NexTek line representing years of innovation in valvetrain technology. The broader valve train lineup — encompassing valves, retainers, pushrods, rocker arms, and guideplates — reflects Manley's roots as a stainless valve manufacturer and their ongoing commitment to precision valvetrain engineering.

For builders assembling a complete rotating assembly, Manley's engine piston sets deliver the forged strength and tight tolerances demanded by serious street and race builds. Rounding out the bottom-end portfolio, Manley engine crankshafts provide the precision-machined foundation that ties a high-performance rotating assembly together. Whether you're building a weekend strip car, a dedicated road-race engine, or a street/strip machine, Manley manufactures components engineered to handle extreme RPM and horsepower demands.
