McLeod Racing RST HD Twin w/ Aluminum Flywheel - 09-10 / 12-21 Dodge Challenger 5.7L/6.4L - 130T
A six-speed Challenger with a blower, a big cam or a 392 tune quickly outgrows the factory clutch, but a full metallic race twin is more than many owners want to live with on the street. McLeod Racing 6344907MD, the RST HD twin disc with an aluminum flywheel, is cataloged for 2009-2010 and 2012-2021 Dodge Challenger 5.7L and 6.4L Hemi cars with the manual transmission. McLeod positions the RST HD between its street RST and harder-hitting RXT twins and rates it for up to 950 horsepower.
The RST HD uses two discs with a floater between them, bolted to an adapter ring on the flywheel. What sets the HD apart is the hybrid friction. McLeod describes one side of each disc as full-face organic for smooth, durable engagement, and the opposite side as segmented ceramic for more bite once the load goes up. The result is a clutch that still drives like a street car in traffic but holds when a supercharged Hemi is on boost or the car is launched on drag radials. McLeod also lists a lighter-than-stock pedal feel, which is the main reason Challenger owners choose a twin over a single heavy-clamp disc.
This kit includes a McLeod aluminum flywheel with a 130-tooth ring gear, so rotating mass drops and the engine revs more freely between shifts. The shipping weight is about 44.8 lb.
Do a roll-on in fourth gear from around 2,000 rpm and watch whether rpm rises without the car pulling harder. Before replacing the clutch, check that the slave cylinder and master cylinder hold a firm pedal and that the pedal returns fully. McLeod's install checklist stresses finding the cause of the first failure: if oil from a rear main or input seal is on the old disc, fix the leak first or the new clutch will fail the same way. Our slipping diagnosis guide covers the checks, and the manual versus automatic repair cost guide helps estimate the labor.
The part is cataloged for 2009-2010 and 2012-2021 manual Challengers with the 5.7L or 6.4L Hemi. The 2011 model year is skipped on purpose: McLeod builds a separate 2011 assembly, which we stock in its RST form as the 2011 Challenger RST twin. Three cautions before ordering. First, the 2009-2010 SRT8 used the 6.1L Hemi, which is not named in this part's description, so 6.1 owners should send the VIN. Second, the supercharged Hellcat is not listed. Third, every 2008 Challenger was an automatic, so a 2008 needs a converted car and a confirmed input spline. Send the year, engine and VIN if anything about your drivetrain is not stock. More drivetrain hardware is in our hard parts department.
These points come from McLeod's RST and RXT twin disc installation instructions:

No. McLeod builds a separate assembly for the 2011 Challenger. This part is cataloged for 2009-2010 and 2012-2021 5.7L and 6.4L manual cars.
The part description names the 5.7L and 6.4L only. Send us the VIN and we will confirm before you order.
Yes. This kit includes a McLeod aluminum flywheel with a 130-tooth ring gear along with the twin disc assembly.
McLeod places the RST HD between the two. The RST uses organic facings, the RXT uses metallic facings for more holding power, and the RST HD combines organic and segmented ceramic friction for more bite while keeping street manners. McLeod rates the RST HD for up to 950 horsepower.
McLeod recommends about 1,200 normal clutch cycles of regular street driving with traction control off, and says not to break it in on a chassis dyno.
