Crane Cams Engine Valve Spring Kit

Crane Cams Engine Valve Spring Kits: Valvetrain Precision from a Racing Legend

When it comes to building a reliable, high-revving valvetrain, few names carry more weight than Crane Cams. Founded in 1953 by Harvey Crane Jr. in the corner of his father's machine shop in Hallandale, Florida, the company was born out of a machinist's obsession with precision — and that DNA runs straight through every valve spring kit they ever produced. For decades, Crane Cams earned a reputation as an internationally respected leader in camshafts, valvetrain, and ignition components, with a camshaft database exceeding 80,000 profiles — the largest in the industry.

Valve springs are one of the most mechanically stressed components in any performance engine. Their job is deceptively simple: ensure the valve follows the camshaft lobe accurately at every RPM. When springs are too weak, soft, or improperly rated for the cam profile, the valve "floats" at high RPM — robbing power, causing misfires, and potentially causing catastrophic engine damage. That's why Crane Cams approached engine valve spring kits the same way they approached everything else: with engineering rigor and a focus on correct cam-to-spring matching.

What Makes Crane Cams Valve Spring Kits Stand Out

Crane's valve spring kits are engineered as complete, coordinated systems rather than a loose collection of springs and hardware. Each kit is designed to work in concert with Crane's cam profiles, ensuring the correct installed height, seat pressure, open pressure, and coil-bind clearance for a given application. Key features across the Crane valve spring kit lineup include:

• Heat-treated springs that can be installed in most cylinder heads with no machining required, making them an accessible upgrade even for mild street builds.
• Chrome moly steel retainers offering high strength for demanding performance and street/strip applications.
• Titanium retainer options for serious builds where reducing reciprocating weight at the valve is critical to high-RPM stability and responsiveness.
• Single spring with damper configurations rated for specific spring rates (such as 330 lb/in) and defined coil-bind heights, providing predictable, documented performance.
• Dual spring kits designed for more aggressive hydraulic roller and mechanical roller cam applications, where higher valve lift demands greater open pressure and superior spring control.
• Kits suited for hydraulic roller cam applications with valve lift up to 0.560 in. and RPM ranges extending to 6,500 RPM and beyond.

Engineering Pedigree Backed by Racing History

Crane Cams was a pioneer in bringing aluminum valve spring retainers to the performance market, and the brand was among the first to popularize roller rocker arms and patented roller tappets for widespread use. Racing legends including "Grumpy" Jenkins, Don Nicholson, and Don Schumacher all trusted Crane valvetrain components on the track. That race-proven heritage translates directly into the quality standards baked into every valve spring kit Crane produced.

Because Crane valve spring kits are engineered as a matched system — springs, retainers, locks, seats, and seals included — they remove the guesswork from valvetrain assembly. Whether you're unlocking suppressed horsepower in an otherwise stock engine or building a dedicated performance combination around a new cam, a Crane valve spring kit gives you the correct components, correctly rated, right out of the box.
