McLeod 10-14 Shelby GT500 RXT 1200 Twin Disc Clutch Kit
A 2010 to 2014 Shelby GT500 with a smaller pulley, a bigger blower or a built 5.4L or 5.8L makes torque the factory clutch was never sized for. The McLeod 6975-07HD is the RXT 1200 HD twin disc in McLeod's modular base plate format, aimed at GT500 owners who need serious holding power but still drive the car on the street.
Instead of one large disc, the RXT uses two ceramic lined discs separated by a floater plate, which doubles the number of friction faces gripping the input shaft. The HD pressure plate adds clamp load over the standard RXT, and that is where the 1200 rating comes from: McLeod rates the RXT 1200 for about 1200 crank horsepower while keeping pedal effort close to stock. The discs ride on a sprung hub with a 1-1/8 inch by 26 spline, the input size of the Tremec TR-6060 six-speed used in every 2010 to 2014 GT500.
The modular design is what sets this part number apart. The pressure plate, floater and discs are built up on a steel base plate that bolts to the flywheel, and the kit does not include a flywheel. That makes it a good fit if you already run a flywheel McLeod lists for this assembly, or if you are upgrading from a lighter RST and want to keep your existing flywheel.
Check for slip with a high gear pull from low rpm and watch whether the tach rises ahead of the speedometer. Then rule out hydraulics: an internal slave cylinder leak or a soft, sinking pedal can keep the clutch from fully clamping and mimic a worn disc. Also inspect the flywheel you plan to reuse for cracks, blue spots and taper, because this kit mounts to it. Our manual versus automatic repair cost guide covers how labor stacks up when the transmission has to come out.
The McLeod catalog description lists this kit for the 2010 to 2014 Shelby GT500, which covers both the 2010 to 2012 cars with the supercharged 5.4L and the 2013 to 2014 cars with the 5.8L, all with the TR-6060. The same assembly is also cataloged for the 2009 to 2017 Dodge Viper. Because the flywheel is not included and must match the base plate, confirm which flywheel you are running before you buy, or send us your year and VIN and we will check the pairing. If you do not need the 1200 rating, the standard RXT modular assembly and the organic faced RST modular assembly use the same layout with a softer pedal and engagement. Owners of an earlier 2007 to 2009 car should look at the RXT HD with steel flywheel for the 07-09 GT500. Browse the rest of our clutch kits in the rebuild kits department.

No. The 6975-07HD is the modular base plate version. It includes the pressure plate, two ceramic discs, floater plate and pilot tool, and it bolts to a compatible flywheel you supply.
McLeod lists it for the 2010 to 2014 Shelby GT500, which spans the 5.4L cars and the 2013 to 2014 5.8L cars, all using the TR-6060 with a 1-1/8 x 26 spline. Confirm your flywheel matches the base plate.
The HD uses a higher clamp load pressure plate. McLeod rates the RXT 1200 for about 1200 crank horsepower, versus roughly 1000 for the standard RXT, with a pedal that is still close to stock.
This part number is cataloged for 2010 to 2014. Earlier cars have their own McLeod kits, such as the RXT HD with steel flywheel for the 2007 to 2009 GT500.
Plan on a pilot bearing and a new slave or release bearing, since neither is listed in the kit. Resurface or replace the flywheel if it is heat checked.
McLeod recommends about 1200 normal engagements in street driving with traction control off, shifting through the gears, and says not to break the clutch in on a chassis dyno.
