KEVLAR® Pilot Bushing

The nylon KEVLAR® composite absorbs the vibration that the Ford diesels create. This bushing can also be used as a repair bushing to run with a scored input shaft thus saving dollars on the cost of a new input shaft.

With all our Ford clutch kits, a Kevlar pilot bushing will be included. This is a $40 value!


This clutch design will offer a very soft pedal. When truck is modified and under load the clutch pedal may stick to the floor.


Remove the helper spring on the clutch pedal. By doing this, it will not only firm the clutch pedal up some, but resolve any clutch pedal inversion problems.

A few months later and already a problem
Austin (Ohio) | November 28th, 2011
I bought this clutch about 5 months ago and it is a great clutch and a much softer peddle. However the KEVLAR bushing has already failed and needs to be replaced

Under load my MU1944 chatters going forward & reverse, any suggestions? MU1944 installed 7/13 about 5K since. Under Load it chatters going forward some,reverse chatters real bad. Any suggestions on what the I need to do?

The Superchips tuning can be run on a stock vehicle. However, it is highly recommended that you install an intake and exhaust system to really maximize the performance that you’ll get with a tuner.
Which MU1944 Kit do you have installed? If it's the Feramic linings, you'll notice the chatter as it's just part of the design. South Bend Clutch suggests that when backing up with a load you put the truck in low range and take your time. Along with going forward it's important to make sure you are in your first forward gear.
