Street legal performance cars today are more powerful than ever before. It would seem that while a decade ago 500 hp made you the big dog in your hometown, today it’s just the starting point.
Many of those that are making these insane power levels are also still rowing their own gears. If you’re rowing those gears, and you’re not driving what would be considered a full-on race car, then you’re probably running something heavy duty in the clutch department.
McLeod’s RST street clutch for cars up to 800HP
The RXT street clutch can handle up to 1,000 HP and the RXT1200 can Handle a Whopping 1200 Crank Horsepower!
Enthusiasts have been turning to McLeod Racing for just such a clutch solution in their RST and RXT line. These clutches can handle up to 1,200 hp but still offer a comfortable pedal feel that won’t leave you massaging a charlie horse after a trip through downtown at rush hour.
That being said, there’s been confusion by some installers over the years as to how to install the adapter ring that comes with and is necessary for the use of a RST or RXT clutch. Some applications don’t include a flywheel, though you can purchase one separately.
In an effort to minimize part numbers as well as both development expense (as well as expense to the customer), McLeod engineered just three adapter rings to fit most applications. Each kit includes the proper adapter ring. Orienting and installing these rings can be a frustrating affair. They’re not simply stamped, “Ford 4.6” or “Chevy 6.0”. This can make fitting the ring to the flywheel a puzzling scenario.
The first adapter ring is our large red ring. This ring is most commonly used in all part numbers that start out as 6911 or 6921. This adapter ring fits all of the large diameter flywheels such as the following:
Chevy 168T
Chrysler 143T, 172T
Ford 164T, 176T, 180T, 184T
Buick, Olds, Pontiac 160T, 166T
Our next ring is our small black ring. This ring is most commonly used in part numbers that start out as 6913 or 6923. This adapter ring fits all of the small diameter flywheels such as the following:
Chevy 153T
Chrysler 130T
Ford 157T
Buick, Olds, Pontiac 153T, 156T
Our last ring is our large gold metric ring. This ring is most commonly used in part numbers that start out as 6912 or 6932. This adapter ring fits all of the metric flywheels that are found on new model cars such as the following:
Chevrolet/Pontiac 168T LS-X 1997-2004 LS1/LS6 Flat Style Flywheel.

Break-In Procedure
All McLeod street performance clutches require a Break-In Period of 500-750 miles of street, stop and go type of driving prior to driving at wide open throttle. This mileage is required to properly seat the disc with the pressure plate and the flywheel. The mileage listed will provide about 1200 apply and release cycles to the clutch assembly.
DO NOT run the vehicle on a chassis dyno prior to full Break-In procedure.
Important: During performance driving and break-in, all traction control devices must be turned off or clutch slippage will occur!

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 finger nail 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 pressure plate and towards the transmission. (in most cases)
2. Worn or damaged clutch linkage, leaf springs, bushings, mounts, u-joints, CV joints, engine mounts, transmission mounts.
3. A flywheel that has not been resurfaced properly, has hot spots, has excessive run-out and or incorrect flywheel step.
4. Pressure plate or disc that is bent.
5. Defective pressure plate and or disc.
6. An engine that is not tuned properly.
7. A disc that either lacks enough marcel or has no marcel at all.
2. Worn or damaged or improperly adjusted clutch linkage.
3. Improperly bled or faulty hydraulics.
4. Flywheel improperly surfaced, machined too thin or not resurfaced before new clutch was installed.
5. Damaged or bent pressure plate and or disc.
6. Clutch disc hub hitting the flywheel bolts.
7. Improper clutch disc thickness.
8. Bent input shaft.
2. Misaligned bellhousing.
3. Wrong fluid type used in transmission.
4. Worn transmission parts i.e. synchro gears and/or bent shift fork.
5. Pilot bushing worn or binding on input shaft
2. Oil or grease on friction surfaces.
3. A clutch that is not designed to hold the amount of power the being made.
4. A clutch not design for the type of driving being done i.e. using a clutch designed for the street at the track.
5. Improper clutch adjustment, bearing free play.
