Parts for the
The SM465 is arguably one of the greatest four-speed transmissions ever built, and reconditioning one is a worthwhile project.
Our master rebuild kit has been assembled for our customer's rebuilds as well as our own. It is the most complete kit we've seen anywhere and features all the consumable and wear item components.
Our kit standardizes the SM465 thrust washer and endplay and we recommend that you use the supplied shaft bushings with the supplied thrust washer for simplicity.
There are two versions of our rebuild kit, each compatible with all 2wd, 4wd and conversion 465's:
- The first and most common kit is for 1968-1987 versions as well as 1988-1991 versions with the narrower .68" front bearing.
- The second kit is for the 1988-1991 version - typically with the aluminum top cover - with the wider .83" front bearing. The only way to know this version is to remove the front bearing retainer and check for a #211 bearing or to remove it and measure its width.
It is very common for our customers to do top-level rebuild work, using good methods and by following our included instruction guide.
We suggest the rebuilder have access to a set of snap ring pliers, a bearing puller and a hydraulic press.
Essentially all parts for the SM465, including gears, shafts, factory adapters & tailhousings, retainers, etc. are available new and affordably so. Our parts ordering module is provided below. For anything not shown, contact us.
