Replace your GM bellhousing clutch release arm pivot with either the original style, or an adjustable version.
This adjustable release arm pivot is our recommendation. It gives height variability, allows more distance from the rear of the release arm to bellhousing window for greater articulation and reduced strain on the bellhousing boot.
The adjustable pivot provides almost 3/8" more height than the factory pivot.
Most GM bellhousings requiring a release arm pivot.
While sometimes not needed in this application, it is priceless when clearances dictate its use. With all the variabilities in flywheel and clutch height, we highly recommend its use. Further information is here.
Installation is the same as a stock part. The adjustable version requires setting the height and locking position.
We strongly recommend that the installer read our Guide to Clutches, Linkages & Bellhousings, to best understand the above arms and the clutch system, generally. Throws and clearances are discussed there and adherence to those methods will yield a successful installation.
