McLeod RXT Clutch Kit 2016 Ford Mustang GT 350 w/ Aluminum Flywheel
The McLeod 6337807M is the RXT Street twin-disc clutch with a dedicated billet aluminum flywheel for the Shelby GT350 and its 5.2L flat-plane-crank Voodoo V8. GT350 owners shop for it once a supercharger, nitrous or a hard track schedule has pushed the factory clutch past its limit: the tach flares on a full-throttle shift, the car smells of hot friction after a session, or the original clutch is simply worn out and they want one that will never be the weak link again.
From the factory, the Voodoo makes 526 hp at 7,500 rpm and 429 lb-ft at 4,750 rpm, and every GT350 sends that through a TREMEC TR-3160 six-speed manual. A twin-disc clutch splits the clamping job between two ceramic-lined discs with a floater plate between them, so it holds far more torque than a single disc of the same size without needing a brutal pedal. McLeod rates the RXT Street family at up to about 1,100 hp and describes the pedal as lighter than stock, which matters on a car that sees daily traffic as well as track days.
This part number pairs the clutch with a billet aluminum flywheel: 8-bolt crank pattern, zero balance to suit the Voodoo, a 164-tooth ring gear and discs splined 1-1/8 in. x 26 for the TR-3160 input. Aluminum cuts rotating mass, so the engine revs up and drops faster between shifts. Expect quicker engagement and more driveline noise than the factory setup; our guide to lightweight vs stock flywheels explains what that feels like on the street, and twin disc vs single disc covers the clutch side.
Make sure the problem is the friction pack and not the hydraulics. A soft or sinking pedal, a leaking slave or air in the line will keep the clutch from fully applying or releasing and can mimic slip or hard shifting. Our clutch slipping guide lays out a top-gear load test and the hydraulic checks to do first, and clutch chatter on takeoff covers engagement shudder. If the GT350 also grinds going into gears, read up on the gearbox side in our TREMEC TR-3160 problems guide, since synchro wear is a separate repair. For overall budget, see automatic vs manual repair cost.
Our listing is for the 2016 Ford Mustang Shelby GT350 with the 5.2L V8 and six-speed manual. McLeod's own application notes for this part number describe the 2015-2020 GT350 5.2L with an 8-bolt crank and a 1-1/8 in. x 26-spline input, so it should also suit other GT350 years, but match three things on your car before ordering: the 8-bolt crank flange, the 26-spline input shaft and a starter that engages a 164-tooth ring gear. It is not for the 5.0L Coyote Mustang GT, which uses a different gearbox and clutch. If your car has a swapped gearbox or aftermarket bellhousing, send us the details or your VIN before purchase.

It is listed for the 2016 Shelby GT350, and McLeod describes the application as the 2015-2020 GT350 5.2L with an 8-bolt crank and 1-1/8 in. x 26-spline input. Confirm those details and a 164-tooth ring gear on your car, or send us your VIN.
No. This kit is built around the GT350 5.2L Voodoo and its TR-3160 gearbox. Coyote GT cars need a different McLeod part number.
McLeod rates the RXT Street twin at up to about 1,100 hp. The stock Voodoo makes 526 hp, so this kit leaves plenty of room for a supercharger build.
Yes, but the engine will lose rpm faster between shifts, so smooth launches take a little more throttle. Expect some extra gear rattle and driveline noise compared with the factory flywheel.
The clutch hydraulics use brake fluid. Fill and bleed with the fluid type printed on the reservoir cap, and bleed fully after the install so both discs release.
