McLeod RST and RXT Adapter Ring Diagrams Make Installation Easier

View Video

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 (1955-2000) SBC, BBC.

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 (LS 1/2/3/6/7)

Ford 164T Modular 4.6L, 5.0L (Coyote with Flywheel Change) 5.4L

NOTE: This Adapter will NOT fit 2011-17 Coyote OEM Flywheels with the factory 9 bolt pressure plate pattern. Aftermarket flywheel with standard 11" OHC Pattern 1999-2010 used.
