McLeod RXT Clutch 07-09 Mustang Shelby GT500 w/Steel Flywheel
The 2007 to 2009 Shelby GT500 left the factory with a supercharged 5.4L making 500 horsepower, and owners who add a bigger pulley, a larger blower or a tune quickly find the limit of the stock clutch. The McLeod 6918-07HD is the heavy duty RXT twin disc for that car, supplied with a billet steel flywheel, a 164 tooth ring gear, zero balance and discs splined 1-1/8 x 26 for the GT500's TR-6060 six-speed.
This is the top of McLeod's twin disc street range. Both discs are ceramic lined and the pressure plate has a higher clamp load than the standard RXT, with strap drive between the plates. McLeod's older catalog copy calls it the RXT 1200 and rates it at 1,200 crank horsepower; the current RXT HD copy rates it up to 1,300 horsepower. Either way it is aimed at supercharged, turbo or nitrous cars that still get driven to the track and back.
The billet steel flywheel bolts to the 8-bolt crank of the 5.4L. Steel was chosen here for street use: its extra inertia helps a heavy car leave a stop cleanly and keeps the clutch from being slipped as much in traffic. Ceramic friction engages more firmly than organic, so expect a positive, quick engagement point and a moderate pedal.
A high-gear, low-rpm full-throttle test shows slip clearly: engine speed jumps ahead of road speed. Then check the hydraulics. A leaking slave, an old master cylinder or air in the line can stop full release or full clamp and mimic a worn disc. If there is oil on the old disc, find the leak before installing anything new. Our slipping diagnosis guide covers the checks in order, and the repair cost guide shows typical labor for a clutch job.
This part is listed for the 2007-2009 Ford Mustang Shelby GT500 with the 8-bolt crank, 1-1/8 x 26 spline input and a 164 tooth ring gear, zero balance. The 2010-2014 GT500 uses a different McLeod part number; for those cars see the 10-14 GT500 RXT 1200 kit. If your car has been swapped to a different transmission or a non-stock crank, send us the year, VIN and parts list so we can confirm the spline and bolt pattern. Want a softer street clutch for a lightly modified car? Compare the standard RXT 6918-07 and the organic RST HD for the 07-09 GT500.

No. This kit is for the 2007-2009 GT500. The 2010-2014 cars use a different McLeod part number, such as the 6975-07HD RXT 1200 kit.
McLeod's older RXT 1200 description rates it at 1,200 crank horsepower, and the current RXT HD description rates it up to 1,300 horsepower. It is built for supercharged, turbo and nitrous street and strip cars.
Yes. It comes with a billet steel flywheel for the 8-bolt crank with a 164 tooth ring gear and zero balance, along with the pressure plate, two ceramic discs, floater plate and pilot tool.
Ceramic discs engage more quickly than organic ones, but McLeod describes the pedal effort as moderate and the clutch as streetable. If comfort matters most on a mildly built car, the RST HD for the 07-09 GT500 is the softer choice.
The pilot bearing, and the release bearing if it shows any wear. Fix any oil leak at the rear main or input seal first, and bleed the clutch hydraulics with fresh fluid.
