McLeod Racing RST HD Twin - For Small Diameter Flywheel - Black Ring - 1-1/8 x 26 Spline
Running a small-diameter flywheel, such as a Chevy 153-tooth, Ford 157-tooth or Chrysler 130-tooth, and making more power than your single-disc clutch can hold? The McLeod 6913-07MD is the RST HD twin-disc assembly on McLeod's small black adapter ring, made to bolt to that flywheel with a 1-1/8 in. x 26 spline input. Buyers usually find it after a clutch starts slipping on the top-end pull, smells hot after a few launches, or after a high-clamp pressure plate made the pedal miserable in traffic.
Small-diameter flywheels limit how big a single disc can be, and a smaller disc holds less torque. A twin-disc stack gets around that by using two discs and a floater plate inside the same footprint, so total friction area goes up without a heavier spring. McLeod's HD discs are organic on one face for street engagement and segmented ceramic on the other for grip, and the line is rated up to 950 hp. The black ring is the spacer that adapts the stack to a small flywheel's pressure plate bolt pattern.
Before blaming the clutch, bleed the hydraulics, inspect the slave or release bearing for leaks, and look for oil from the rear main or input seal. Adjust any cable or linkage so the bearing is not riding the fingers. Our slipping diagnosis guide covers how to separate clutch slip from other drivetrain faults, and the manual transmission repair cost guide explains what the full job usually involves.
This is a ring version with no flywheel and no specific vehicle years. It fits when your flywheel is small-diameter and your input shaft is 1-1/8 in. x 26 spline. McLeod's black-ring list covers Chevy 153T, Chrysler 130T, Ford 157T, and Buick, Olds and Pontiac 153T and 156T flywheels. Count the ring gear teeth before you order.
If your count is 168T Chevy, 164T Ford or another large pattern, you need the red-ring McLeod 6911-07MD instead. Prefer softer all-organic discs at up to 800 hp? The black-ring McLeod RST 6913-07 is the step down; the ceramic McLeod RXT 6923-07 is the step up for track cars. Ford small blocks with a 10-spline gearbox need a different spline, so send us your engine, tooth count and transmission if you are unsure.

McLeod's small black ring fits small-diameter flywheels: Chevy 153T, Chrysler 130T, Ford 157T, and Buick, Olds and Pontiac 153T and 156T.
No. It bolts to your own compatible flywheel. Resurface it, and confirm any dowel pins are installed before mounting the ring.
No. A 168T Chevy flywheel is a large-diameter pattern and needs the red-ring 6911-07MD. LS-X metric 168T flywheels need McLeod's gold metric ring.
The RST uses all-organic discs rated to 800 hp. The RST HD adds a segmented ceramic face on each disc and is rated to 950 hp. RXT units use ceramic discs for higher-power and competition cars.
McLeod's checklist says to replace a worn throwout bearing during the install. Match the bearing to your transmission and hydraulic or mechanical linkage.
