About this product

If your 2007-2009 Shelby GT500 is a street car first and it has started slipping since the pulley, tune or exhaust went on, the McLeod 6908-07 is the clutch built for that exact situation. It is McLeod's RST twin disc with two organic discs and a dedicated billet steel flywheel, sized for the 5.4L supercharged engine's 8-bolt crank, a 164 tooth ring gear, zero balance, and the 1-1/8 inch by 26 spline input of the six-speed. McLeod calls the RST its economically priced twin, made for high horsepower street cars rather than competition.

What the RST twin does in a 2007-2009 GT500

A twin disc clutch doubles the number of friction faces, so it can hold far more torque without needing a brutal pressure plate. That is why McLeod can rate the RST for about 800 horsepower while keeping the pedal lighter than stock. In the 6908-07 both discs are organic, which gives the smoothest, most forgiving engagement of McLeod's twin disc family. A floater plate sits between the two discs, and the pressure plate bolts to the supplied steel flywheel through McLeod's adapter ring.

The steel flywheel is the right choice for a heavy car that sees daily traffic. Its mass helps the GT500 pull away cleanly without dragging the clutch, and idle and cruise behavior stay close to factory. McLeod itself says this unit is not intended for competition; for drag strip or road course duty it points owners to the RXT line, which uses ceramic discs.

Symptoms that point to a new clutch

How to confirm before ordering

A low-rpm, high-gear pull is the simplest test: if the tach climbs faster than road speed, the clutch is slipping. Then check the release side, because a slave or master cylinder problem can feel like a bad clutch. Look for fluid loss, a pedal that does not return fully or gears that grind when the clutch is down. Fix any oil leak at the rear main or input seal before the new discs go in, or they will glaze quickly. The slipping diagnosis guide walks through the order of checks, and flare vs slip helps you tell the difference while driving.

Fitment

McLeod lists 6908-07 for the 2007, 2008 and 2009 Ford Mustang Shelby GT500: 8-bolt crank, zero balance, 164 tooth ring gear, 1-1/8 x 26 spline. It is not the part for the 2010-2014 GT500, which takes a different McLeod assembly such as the 6975-07HD RXT 1200. If the engine, crank, transmission or starter is not stock, send the year, VIN and what has been changed so we can confirm. Need more holding power than the organic RST? Compare the RST HD with organic and ceramic discs or the all-ceramic 6918-07 RXT.

McLeod RST Clutch Mustang Shelby Gt500 1-1/8in X 26 Spline W/Steel Flywheel: common questions

Does the McLeod 6908-07 fit a 2010-2014 GT500?

No. It is built for the 2007-2009 Shelby GT500 with the 8-bolt crank. The 2010-2014 car uses a different McLeod assembly, such as the 6975-07HD.

How much power can the RST handle?

McLeod rates the RST twin disc for about 800 horsepower. It is aimed at street cars; McLeod recommends its RXT line for competition.

What is in the box?

Pressure plate, two organic friction discs, a billet steel flywheel, floater plate, adapter ring and a pilot tool. The release bearing and pilot bearing are not listed as included.

Will the pedal be heavier than stock?

No. McLeod describes the RST as having a lighter than stock pedal feel, because the twin disc design gets its holding power from extra friction faces rather than a stiffer diaphragm.

What is the difference between this and the RST HD?

The 6908-07 uses two organic discs for the smoothest street engagement. The RST HD pairs organic with segmented ceramic for more bite and a higher power rating.
