Description
When your Ford small block is making serious power, the factory clutch becomes the failure point. Tilton's ST-246 twin-disc clutch solves this with a ground-up design that's a true performance twin-disc - not a stamped steel pressure plate with a floater bolted on as an afterthought. Drawing from nearly 50 years of championship-winning racing clutch development in F1, NASCAR, IMSA, IndyCar, and Formula Drift, this assembly delivers 850 lb-ft holding capacity while maintaining genuine street drivability.
The engineering advantage starts with a floater plate that's twice the thickness of competitors. This extra mass allows for the sprung hub configuration that dampens engine vibrations and reduces gearbox noise, while eliminating gear clatter and providing superior heat dissipation. The precision-machined aluminum cover delivers higher strength and stiffness than OEM stamped steel designs, sharing technology directly from Tilton's OT-Series racing clutches. The high-mass pressure and floater plates are machined from Tilton's proprietary racing materials for maximum heat capacity and warp resistance, while heavy-duty straps attach the plates to the cover - minimizing noise and ensuring clean release characteristics.
The billet chromoly flywheel features an integrated 157-tooth ring gear that's internally balanced at 0 oz. A precision register system locates the clutch for optimal assembly balance - a far superior approach to the loose-fitting bolts and dowels used with stamped steel clutches. The organic discs use sprung center hubs specifically engineered to dampen engine vibrations and reduce transmission noise, providing the smooth engagement characteristics you need for street use.
This kit fits Ford 289, 302, 351W, and 351C engines running 26-spline transmissions and is compatible with OEM release bearings. Unlike budget alternatives that compromise on materials or engineering, the ST-246 delivers racing-proven technology in a complete bolt-in package. Every component is designed to work as a system, from the precision flywheel register to the heavy-duty plate straps.
