ST-246 Clutch Kits…. Racing Technology applied to the Street.

Tilton has applied their nearly 50 years of experience in racing clutches to develop the ST-246 line of 246mm (9.7”) twin disc clutch kits for the high-performance street market. Unlike many of the “performance clutches” on the market, ST-246 clutches were engineered from the ground up as a true performance twin disc clutch and not an OEM-type stamped steel pressure plate with a floater plate added. ST-246 clutches are designed to provide high torque capacity, low wear rate, smooth shifting and good drivability. All ST-246 twin disc clutch kits include
a billet chromoly steel flywheel and are available with either sprung-hub organic discs (850 lb-ft capacity) or solid-hub cerametallic discs (1250 lb-ft capacity).

Tilton has now applied their nearly 50 years of experience in racing clutches to develop the ST-246 line of twin disc clutch kits for the high-performance street market. Unlike many of the “performance clutches” on the market, ST-246 clutches were designed from the ground up as a true performance twin disc clutch and not an OEM-type stamped steel pressure plate with a floater added. Featuring an aluminum clutch cover that shares technology from Tilton’s championship winning line of OT- Series racing clutches, ST-246 clutches feature heavy duty straps that attach the pressure plate and floater plate to minimize noise. ST-246 clutches are available with either sprung-hub organic discs for street applications or solid-hub cerametallic discs for street/strip applications.

All kits include a billet chromoly steel flywheel that features a precision register for the clutch to provide optimal balance of the clutch/ flywheel assembly.

ST-246 clutch kits for Corvette C7 are designed to work with the OEM slave cylinder. Most importantly, Tilton ST-246 clutch kits offer all this technology at a price point that is very competitive to the other clutches on the market.

Precision machined aluminum clutch cover high-strength, stiffness and better balance than OE-type stamped steel covers.

High-mass main pressure plate and floater plate machined from the same proprietary materials as used by Tilton’s racing clutches, provides high heat capacity and resists warpage. Heavy duty straps attach plates to cover to minimize noise and provide clean clutch release.

Organic disc option, with sprung center hub to dampen engine vibrations and reduce gearbox noise, provides smooth engagement for street use and holds 850 lb-ft of torque.

Cerametallic disc option, with solid center hub for higher strength, provides positive/precise engagement characteristics for streets/strip and holds 1250 lb-ft of torque.

Chromoly steel flywheel provides high strength and long-term durability.  Features a precision register to locate the clutch and provide optimal balance, as opposed to loose fitting bolts & dowels used with stamped steel clutches.
