Kelford Cams: Over Five Decades of Performance Engineering

Few names in the performance aftermarket carry the same weight as Kelford Cams. With over 54 years of manufacturing experience, Kelford has built a global reputation for designing and producing high-performance camshafts and valve train components that are trusted by professional engine builders, amateur tuners, and championship-winning race teams alike. Made in New Zealand, Kelford products are engineered to exacting standards and backed by real-world results — including over 60 race records set by cars running Kelford hardware.

World-Class Camshaft Design and Innovation

At the heart of what Kelford does is camshaft engineering. Kelford dominates the performance aftermarket with world-first camshaft designs and releases, including profiles for the BMW/Supra B58, Subaru FA20, Toyota GR Yaris, and more. These aren't off-the-shelf grinds — Kelford's design team works closely with both amateur and professional race teams to develop solutions tailored to rally, drift, hill climb, circuit, and all-out drag racing applications.

Kelford camshafts are specifically designed for targeted engine applications, providing precise valve timing and lift characteristics. They are made from high-quality materials such as billet steel or chilled cast iron, delivering superior durability and strength. Each profile is engineered to optimize lobe geometry for maximum horsepower, torque, and engine responsiveness at the RPM range that matters most for the intended application.

A Complete Valve Train Solution

The Kelford catalogue includes camshafts, valve springs, and a range of valve train components for leading automotive brands. This means builders don't have to source mismatched parts from multiple suppliers — Kelford's valve springs, retainers, guides, and seals are engineered to complement their camshaft profiles, ensuring the entire system works in harmony under high-load conditions.

Valve train accessories include valve guides and seals, valves, valve springs, and balance shaft deletes for multiple vehicle models including Toyota, Subaru, Nissan, and Mitsubishi. For modern turbocharged platforms like the BMW B58/S58 series, one of the biggest challenges in tuning is working within the constraints of the Vanos and Valvetronic variable valve timing systems — Kelford engineers design their camshaft profiles to work in harmony with these systems, ensuring engine management doesn't fight the new hardware.

Proven on the World Stage

Kelford camshafts have been used in rally racing, drag racing, drifting, and street racing at the highest levels of competition. Kelford cams were used in Formula Drift champion Fredric Aasbo's Toyota GR Supra A90, which produced 1,095 hp. On the drag strip, the Kozmic FHT Subaru completed the quarter mile in 8.05 seconds at 184 mph running Kelford cams, becoming the fastest EJ-powered Subaru on the planet.

With 54 years of manufacturing high-performance camshafts behind them, Kelford has accumulated over 32,000 engine installs and 60+ race records, dyno-proven and trusted by professional engine builders worldwide. Whether you're building a street machine that needs to survive daily driving or a purpose-built race car pushing four-digit horsepower numbers, Kelford Cams has a proven solution for your engine.

Broad Platform Coverage

Kelford Cams are available for Subaru, Nissan, Toyota, Mazda, Mitsubishi, Honda, BMW, Chevrolet, and Ford, as well as custom-made cams for specific applications. An extensive international network of dealers, including local installers, engine builders, and online retailers , ensures that Kelford products are accessible to enthusiasts and professionals around the globe. If your engine platform isn't covered by an off-the-shelf profile, Kelford's engineering team is known to work with customers on custom grind solutions.
