Clutch Release Arms

As discussed in our popular Clutches, Linkages & Bellhousings article, different pressure plates have different ratios, as do the various linkage systems that are native to Jeeps. The following clutch release arms are available to help you get the right amount of travel from your GM engine's clutch in your Jeep.

Release Arm for GM Engine Swaps in Early Jeeps

K-RAV6-N

This release arm is the best choice of release arm for a GM engine swap in 1945-1971 CJ and other models. It's proper length gives the correct release action for GM clutches, and is compatible with the early bellcrank linkage systems found in these earlier Jeeps.

This Novak manufactured part is far superior to the poorly made Buick V6 replacement arms on the market, whose retention springs fail. This kit ships with the our #K-15155 studded pivot ball, shown.

Release Arm for GM Engine Swaps in 1972-1986 Jeeps w/ Mechanical Linkage

RAGM

This release arm is the best choice of release arm for either a GM engine swap in 1972-1986 CJ models, and some FSJ Jeeps - with the factory mechanical release system (not hydraulic). It's proper length gives the correct release action for GM clutches and is compatible with later rod & bellcrank linkage systems found in these Jeeps.

Release Arm for GM Engine Swaps in Jeeps w/ Hydraulic Linkage

RAGH

This release arm is primarily for GM hydraulic release applications. It is the proper length to give the correct release action with hydraulic linkage systems found in Jeeps YJ, XJ and TJ Jeeps when performing a GM engine and bellhousing conversion, or on some earlier Jeeps that may have a custom made hydraulic system. A modified version of this arm is used in our GM Hydraulic Slave kits #HCRC & #HCRB.

This release bearing assembly uses a telescoping and locking design which spans the range of shortest to longest GM throwout beareings that were ever available. It is helpful if the installer wants a one-and-done solution that avoids trips to the parts store, and sometimes for bearing heights that just aren't made anymore by GM or the aftermarket.

Installation Requirements

Installation varies with the application. The arms will install as stock arms do and the linkage will need to be modified to provide correct movement at the release bearing.

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.
