· Higher torque rating than most competitors
· Chromoly integrated ring Gear on a Chromoly Flywheel
· Aluminum Pressure Plate, which means less rotating mass
· A Floater plate that is twice the thickness of most other twin disk clutches, which offers these benefits
1. Allows for a solid hub (1250 lb/ft)
2. Eliminates gear clatter
3. Provides much better heat dissipation
Since 1972, Tilton Engineering has been the leading supplier of small diameter racing clutches. Tilton racing clutches are world-renowned for their performance and reliability, winning championships in nearly every form of motorsport worldwide, including F1, NASCAR, IMSA, IndyCar, SCCA, Formula Drift, and SCORE.
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 the optimal balance of the clutch/ flywheel assembly.
All ST-246 kits, except for Camaro GEN5, Corvette C6, and 2011-2017 Mustang GT can be used with OEM release bearings. ST-246 clutch kits for Camaro GEN5, Corvette C6, and 2011-2017 Mustang GT applications include a Tilton 6000-Series hydraulic release bearing (height preset at Tilton) that is designed to connect directly to the OEM clutch line. 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.
The high-mass main pressure plate and floater plate machined from the same proprietary materials as used by Tilton’s racing clutches provide high heat capacity and resist warpage. Heavy-duty straps attach plates to cover to minimize noise and provide clean clutch release.
Organic disc option, with a 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 a 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.
ST-246 kits paired with a Tilton 6000-Series hydraulic release bearing (height preset at Tilton) that is designed to connect directly to the OEM clutch line.
