McLeod 6306807HD RXT 1200 HD Twin Disc Clutch Kit Corvette C7 LT1 LT4 LSA 26SP

Vehicle Fitment

• 2014-2019 Chevrolet Corvette C7 (LT1 / LT4 | 6.2L V8 | Manual Trans | Excluding ZR1)
• 2009-2015 Cadillac CTS-V (LSA | 6.2L Supercharged V8 | Manual Trans)
• 2012-2015 Chevrolet Camaro ZL1 (LSA | 6.2L Supercharged V8 | Manual Trans)
• 2016-2023 Chevrolet Camaro (LT1 / LT4 | 6.2L V8 | Manual Trans)

Fitment Notes

• Fits GM Gen V LT-series engines with an 8-bolt crankshaft flange - verify your crank bolt pattern before ordering; this does not fit 6-bolt LS-X cranks
• Input shaft: 1-1/8 inch diameter, 26 spline - confirm your transmission's input shaft specification
• Corvette C7 ZR1 is NOT compatible - the ZR1's dry-sump engine requires a dedicated part number
• Flywheel ring gear: 168 teeth - confirm starter engagement compatibility with any swapped bellhousing setups
• Billet aluminum flywheel is included and pre-matched; for the steel flywheel version of this same clutch, order 6406807HD instead
• Compatible with factory hydraulic clutch actuation - no hydraulic conversion required on factory-equipped vehicles
• Requires a 500-750 mile break-in period of street stop-and-go driving before any wide-open-throttle use; do not use a chassis dyno prior to completing break-in
• All traction control systems must be disabled during break-in and performance driving to prevent clutch slip from traction intervention

Features

• RXT 1200 HD twin disc design - higher clamp load than the standard RXT; rated to 1,200 HP crank while remaining streetable with near-stock pedal effort
• Twin ceramic friction disc material - superior heat resistance and holding power compared to organic discs; suitable for both aggressive street driving and strip use
• 9-11/16" disc diameter - application-specific sizing for the 8-bolt LT Gen V platform's flywheel geometry
• Billet aluminum flywheel (168-tooth, included) - significantly lighter than a steel flywheel for faster throttle response and quicker revs; ideal for track-focused and modified applications
• McLeod patented RST/RXT adapter ring (included) - CNC-machined, bolts to the included aluminum flywheel for correct disc-to-flywheel alignment
• Diaphragm pressure plate - provides higher and more consistent clamping force than Borg & Beck long style; factory hydraulic compatible
• Floater plate with retention straps - reduces drivetrain rattle at idle for improved street manners
• Pilot tool included for correct input shaft alignment during installation

Product Description

The McLeod Racing 6306807HD is the RXT 1200 HD Twin Disc Ceramic Clutch Kit with billet aluminum flywheel for GM Gen V LT-series vehicles - covering the 2014-2019 Corvette C7 (LT1/LT4, excluding ZR1), 2009-2015 Cadillac CTS-V (LSA), 2012-2015 Camaro ZL1 (LSA), and 2016-2023 Camaro (LT1/LT4). The defining platform specification is the 8-bolt crankshaft flange used on Gen V LT engines - this is not compatible with the 6-bolt LS-X cranks found in older C5/C6 Corvettes and fourth-gen F-bodies. The 1-1/8" x 26-spline input shaft targets the TR6060 and TR8060 transmissions factory-fitted to these vehicles.

The RXT 1200 HD steps above the standard RXT with higher clamp load, giving it a 1,200 HP rating while maintaining the streetable pedal feel that makes McLeod's twin disc lineup usable as a daily driver. The included billet aluminum flywheel is the primary differentiator between this 6306807HD and the steel flywheel 6406807HD - the aluminum unit reduces rotational mass significantly, improving throttle response and rev-matching feel, making it the preferred choice for track-day use or builds targeting fast lap times. The ceramic disc material handles the heat generated by high-powered LT engines and supercharged LSA applications more effectively than organic discs, and the diaphragm pressure plate is compatible with the factory hydraulic clutch system without any master cylinder or slave cylinder modifications. All traction control must be disabled during break-in; failure to do so will cause clutch slippage and premature wear during the seating period.
