About Darton Sleeves

When engine builders and professional racers need cylinder sleeves they can stake their reputation on, they turn to Darton Sleeves. With over 45 years of experience, Darton Sleeves is committed to product perfection and innovation in engine solutions. Based in Carlsbad, California, Darton International has grown from a focused domestic manufacturer into a globally recognized name in precision engine components.

Darton initially concentrated on steel stampings and precision cylinder sleeves, and among their first customers were legendary names like Milodon Engineering and Keith Black Racing Engines — together pioneering new and innovative ways to manufacture performance cylinder sleeves. That heritage of racing-driven innovation still defines every product Darton makes today.

World-Class Manufacturing

Darton became the first supplier of high-quality centrifugally cast ductile iron cylinder sleeves to meet SAE and ASTM rigid quality control standards, based on their own unique chemistry and pouring process, including shot peening to remove stress. This dedication to metallurgical excellence sets Darton apart from the competition.

Much of Darton's cylinder sleeve material is produced in their Portugal foundry, which is recognized worldwide for excellence in all forms of unique types of centrifugally cast ductile and grey iron. Darton also sources raw material from other domestic and international sources, but all product is made to their exacting chemical standards.

Trusted by the Pros

Darton is the prime sleeve supplier for the Ford SVO, Chrysler Hemi, and GM performance LS series engines, as well as most professional racers in NHRA Racing. From Top Fuel dragsters to street performance builds, Darton's reputation spans every corner of the motorsports world.

Their intended clients range from automotive enthusiasts and manufacturers to racing teams and aviation sectors. Whether you're rebuilding a vintage muscle car, refreshing an import engine, or building an all-out race motor, Darton's extensive catalog has a sleeve for your application.

An Extensive Product Line

Darton's lineup of cylinder sleeves covers an enormous range of applications. Manufactured sleeves and blanks are available for Chevy, Dart, Donovan, Ford, Harley Davidson, Import/European, Keith Black, Mopar, Rodeck, Brodix, and many other platforms, as well as MID sleeves for modern vehicles from Honda, Acura, Nissan, Toyota, Lexus, Porsche, Subaru, Volvo, and more.

For those with unusual or hard-to-find applications, Darton also offers custom engineering solutions. Darton makes it easy to source those difficult and often hard-to-find sleeves for almost any application, and all custom sleeves are made from the same superior-strength ductile iron used in their regular production and high-performance sleeves, including those for Top Fuel and Funny Car.

Beyond sleeves themselves, Darton supports the complete engine rebuild process with engine block solutions and engine cylinder liners — ensuring that builders can source the precision components they need from a single trusted manufacturer. The focus of Darton International's business remains the manufacture and delivery of cylinder sleeves, sometimes referred to as cylinder liners.

Reliability You Can Count On

Darton employs a market strategy aimed at becoming the primary sleeve supplier of choice for small engine shops and OEMs alike. From a weekend rebuild in a home garage to a professional race team's engine program, Darton Sleeves delivers the same uncompromising quality — because when you're building an engine, there's no room for second best.
