Clutch Kit 9-1/4"

Will these heavy duty kits from KaiserWillys fit any 134 ci Willys four cylinder?

Was wondering about going to this larger size when I change the clutch disks.:hurrican:

 

Willys used 9-1/4" Auburn pressure plates with a Borg Beck driven disc.
Your link shows a Borg Beck style of 9-1/4" pressure plate.

I found an actual Borg Beck 9-1/4" pressure plate to be very hard on standard clutch control components. It is a very stiff clutch.
At a minimum you will also need to upgrade your clutch control to the correct 9-1/4" components.
(Clutch Control Lever and Tube Assembly)

Your 134 engine may or may not accept a 9-1/4" clutch depending upon your flywheels vintage.
All post 1961 flywheels should accept the 9-1/4" clutches.
Go remove your bellhousing flywheel inspection cover plate to see if your flywheel has the additional threaded taps around the perimeter.

 

I put one in my '56 and made no changes at all to linkage. That was about 15 yrs ago. I knew nothing about the different types of clutches but this old guy that ran a Willys parts/restoration company where I got all my stuff told me it was a good upgrade, so I put it in. I don't recall if it was stiffer or not.
