Key Features
- 850 lb-ft torque capacity with 246mm twin-disc design [VERIFY: MDL lists cerametallic discs at 850 lb-ft, but Tilton typically rates cerametallic at 1,250 lb-ft and organic at 850 lb-ft - confirm disc type]
- Precision-machined aluminum clutch cover delivers superior strength and balance vs. OEM stamped steel
- High-mass pressure plate and floater plate machined from Tilton's proprietary racing materials resist warpage under extreme heat
- Heavy-duty straps attach plates to cover, minimizing noise and providing clean clutch release
- Billet chromoly 8-bolt flywheel with 130-tooth ring gear and precision register for optimal balance
- 1-1/8" x 26-spline input matches TR6060 transmission specifications
- Includes CSC spacer for proper concentric slave cylinder fitment
- Diaphragm-style pressure plate for consistent pedal feel
Description
When you're pushing serious power through a Gen III Hemi, "good enough" clutches become liabilities. The Tilton ST-246 twin-disc clutch system delivers racing-derived technology engineered specifically for high-performance street and strip applications in 2007 and newer Dodge Challengers equipped with the TR6060 transmission.
Unlike stamped steel "performance" clutches with bolt-on floater plates, the ST-246 was designed from the ground up as a true twin-disc clutch. The precision-machined aluminum clutch cover shares technology from Tilton's championship-winning OT-Series racing clutches, delivering higher strength, stiffness, and dynamic balance than OEM-type stamped covers. The high-mass main pressure plate and floater plate are machined from the same proprietary materials used in Tilton's racing clutches, providing exceptional heat capacity and resistance to warpage that keeps the clutch engaging consistently even under repeated high-load conditions.
Heavy-duty straps attach the pressure plate and floater plate to the cover, minimizing the gear rattle and noise common to other twin-disc designs while ensuring clean clutch release. The billet chromoly flywheel features an 8-bolt pattern with a 130-tooth ring gear and precision register that provides optimal clutch/flywheel assembly balance - a critical detail that separates this system from loose-fitting designs. The 1-1/8" x 26-spline disc configuration matches TR6060 input shaft specifications, and the included CSC spacer ensures proper geometry with concentric slave cylinder setups.
Engineered by Tilton Engineering, the leading supplier of small-diameter racing clutches since 1972, with world-renowned performance and reliability proven in F1, NASCAR, IMSA, IndyCar, SCCA, Formula Drift, and SCORE. Made in the USA.
