Rated 5 out of 5 by from Smooth and Tight I've read many reviews with people saying they had chattering and a hard pedal. I didn't experience any of these issues. However, I made sure all my clutch linkage components were in good working order and also replaced the flywheel and pilot bushing with a roller bearing. Pedal effort was stock-like and I didn't have any chattering from the first time I pulled it out of the garage. Smooth engagement and it holds tight all the way through 6000RPMs - unlike the previous long style clutch that wasn't that old. I put this in a 66 Mustang with a mildly built 289, wide ratio T-10 4 speed, and 3.55 gears in the rear.

Hi: Need a clutch for a 1965, 289, 5 Bolt bell housing engine attached to a top loader 4 speed. (Not sure if it came out of a Mustang or other Ford 65' product). The clutch I removed is 3 lever with a 10.5" disc. Is the SF951 applicable?

Asked by: lclttl2
You may have to change the flywheel since this is a 10 inch clutch.

Will this work a T-5 transmission conversion and do I need to replace the brass pilot bushing with a roller type bearing?

Asked by: Luis Angel
It depends on the bell housing you are using, if you are using a t-5 bell housing than you would want to use a 86-99 10.5 inch clutch, an early style bell housing you can use the SF951 clutch. In either case you will want to use a roller bearing instead of a bushing.

What is the pedal effort? I have a 3200 pound from the 70's in the car now, would like a closer to stock effort. Is it a long style or diaphragm as pictured?

Asked by: BillR289
Stage 1 Spec Clutches always retain a stock pedal effort.
