McLeod 2011 Dodge Challenger 5.7L/6.4L Aluminum Flywheel 1-1/8x10 130T
Own a 2011 Dodge Challenger R/T or SRT8 392 with the six-speed manual and a stock clutch that is slipping behind a supercharger, heads and cam, or just a lot of hard launches? McLeod part number 6344904 is the RST twin disc clutch with a billet aluminum flywheel built specifically for the 2011 model year 5.7L and 6.4L Hemi cars. It is a one-box system: twin organic discs, pressure plate, floater, adapter ring and a 130-tooth aluminum flywheel.
The factory clutch behind the Tremec TR-6060 is a single large disc. The RST splits the clamping work across two organic-faced discs and a floater, which roughly doubles friction area. McLeod rates the RST to handle about 800 horsepower while keeping a lighter-than-stock pedal, because two discs need less clamp load to hold the same torque. The organic facings engage smoothly, which is why McLeod aims the RST at high-horsepower street cars rather than competition; its RXT line is the step up for racing. The aluminum flywheel cuts rotating mass so the Hemi revs more freely between gears.
What makes this part number different is the input spline. McLeod's listing specifies a 1-1/8 inch, 10-spline disc hub and zero balance for 2011, which is why the 2011 car has its own number instead of sharing the kit McLeod builds for the other Challenger years. If your car is a 2009-2010 or 2012-and-later model, look at the McLeod RST kit for 09-10 and 12-20 Challengers instead.
Do a high-gear pull with the car warm and watch for rpm climbing faster than speed - that is slip. Then rule out what a new clutch will not fix: a leaking slave cylinder or air in the hydraulics causes drag and hard shifts, and a rear main seal leak will soak the new discs. Our transmission slipping diagnosis guide covers separating clutch slip from other faults, and the manual vs automatic repair cost guide helps if the gearbox itself is also in question.
This kit is listed for the 2011 Dodge Challenger with the 5.7L or 6.4L Hemi and the six-speed manual. 2011 was the first year of the 6.4L (392) SRT8. It does not fit automatic cars or the V6. Because McLeod splits Challenger kits by year and spline, slide the old disc onto your input shaft or count its splines before ordering, or send us your VIN and we will confirm. More driveline parts for the platform are on our hard parts page.

McLeod lists this kit with a 1-1/8 inch 10-spline disc hub for the 2011 model year. The kits for 2009-2010 and 2012-up cars use a different spline, so the two are not interchangeable.
Yes, the listing covers 2011 Challengers with the 5.7L or 6.4L Hemi and the six-speed manual. It does not fit automatic or V6 cars.
McLeod rates the RST around 800 horsepower. For racing or more power, McLeod points buyers to its RXT ceramic kits.
No. McLeod describes the RST as lighter than stock pedal feel, because two discs share the load.
Inspect and usually replace the pilot bearing and throw-out bearing, fix any oil leaks, and check the hydraulics. McLeod also recommends replacing a worn release bearing while the transmission is out.
