MCLEOD RST HD TWIN DISC CLUTCH KIT | 950HP STREET & TRACK
$1025.00 - $1995.00
Intended for the high horsepower street and track fan, the McLeod RST HD twin disc clutch kit bridges the gap between our flagship RST and RXT systems. Able to handle 950hp, this clutch can handle serious horsepower and still remain highly street-able. The unique hybrid clutch discs—featuring a smooth-engaging organic material on one side and a high-bite segmented ceramic material on the other—provide an ideal balance of soft pedal effort and enhanced torque-holding capability. This unit is perfect for the driver who pushes their vehicle harder on the street and demands track-ready performance without harsh engagement or excessive drivetrain stress.

1. Change the pilot bearing.
2. Break the clutch in according to the instructions provided.
3. Ensure proper bellhousing alignment.
4. Resurface the flywheel. This is a critical step to guard against clutch chatter/shudder. We recommend a very coarse surface texture from a stone grinder. Something that if you ran your fingernail across the flywheel, the texture would catch your nail.
5. Inspect the entire clutch system, including hydraulics and linkage. Replacement of the Hydraulic slave with an OEM replacement is critical.

- A Single disc application is installed with the completely flat side facing the flywheel. The protruding side of the hub (side with springs) assembly will face up towards the pressure plate ( in most cases)
- A double-disc unit will have both hubs with the protruding side of the hub face up towards the pressure plate and towards the transmission. (in most cases)
Yes. The pins help to ensure proper alignment of the pressure plate and add strength.
The biggest factors in clutch life are the way it is used and the output of the engine. McLeod Clutches are designed for maximum life but that life can be shortened by using much stickier tires than stock, stop and go driving, track use, tires of larger diameter and other factors that place added stress on the clutch.
We would like to see 500-750 miles of stop & go city driving. With no drag racing or dyno tuning. Make sure to drive in stop & go city driving to actuate the clutch 1200 to 1500 times. You can drive the car 600 miles on the interstate and only shift the car 5 or 6 times and not break in the clutch.

The McLeod RST HD achieves this balance through an innovative hybrid twin-disc design that places less stress on your drivetrain. Instead of using identical friction materials on both sides of the discs, the RST HD uses a dual-performance configuration:
-
The Street Side: Features a premium, full-face organic friction material that delivers the ultra-smooth engagement, zero chatter, and soft pedal effort you expect from a daily driver.
-
The Track Side: Features a high-coefficient, segmented ceramic friction material that provides the aggressive bite and massive torque-holding capacity needed to handle up to 950 HP.
By engineering these two distinct materials to work together, McLeod bridges the gap between comfort and capability—giving you an economically priced twin-disc clutch with excellent street manners that won't slip when you push it on the track.
