Max-Torque Clutch & Components
Max-Torque Clutch & Components: Built for Performance Since 1957
Max-Torque has been at the forefront of centrifugal clutch engineering for small engine applications for well over six decades. Founded in 1957, the brand has earned a reputation as a genuine innovator in the go-kart and mini bike world — a reputation built not on marketing, but on engineering decisions that competitors have tried, and often failed, to replicate. When you shop the Clutch & Components category, Max-Torque stands out as a benchmark brand trusted by weekend hobbyists and competitive racers alike.
The SS Centrifugal Clutch: An Industry Icon
The flagship of the Max-Torque lineup is the "SS" clutch — a name derived from its six-shoe centrifugal design. This clutch features a multi-shoe layout with an integrated, interchangeable drive sprocket, giving riders the flexibility to dial in drive ratios for their specific application. A variety of clutch springs are available to vary the engagement RPM, making it equally at home on a leisure fun kart or a performance racing application such as the Briggs 206 racing engine.
What truly separates Max-Torque clutches from imitations is the engineering in the details. An exclusive ground sleeve delivers a 10-microfinish surface for smoother bushing contact, reduced friction, and extended service life. A stainless-steel garter spring resists rust to ensure consistent, repeatable shoe pressure lap after lap. Rather than relying on needle bearings, Max-Torque uses a sintered metal bushing system lubricated with specially formulated grease — a design that is more forgiving of both heat and contamination than needle-bearing alternatives. The result is a clutch that can handle exposure to dirt, oil, and water without sacrificing engagement consistency.
A Full Ecosystem of Clutch Components
Max-Torque doesn't just sell complete clutch assemblies — the brand supports a full ecosystem of serviceable replacement parts, which is a key reason it has remained popular in the karting community for generations. Racers and builders can source individual clutch shoes (including wedge-style heavy shoes for demanding applications), stainless-steel replacement springs, clutch drums, drive sprockets in multiple tooth counts, snap rings, retaining rings, set screws, keys, and replacement bushings. The SS clutch can be completely disassembled with snap ring pliers, making field maintenance and part-by-part rebuilds straightforward even at the track.
The product range also extends to fit popular engine platforms including Honda GX-style engines, clone engines, and Predator powerplants — covering a wide range of bore sizes (5/8" and 3/4") and chain pitches (#35, #40, #41, and #420). For vintage kart enthusiasts, Max-Torque even offers clutches tailored to classic engines from the 1950s through the 1970s.
