Consider the following before mailing:

We wish we were able to answer general technical questions, but the sheer volume of mail we get requires that we focus only on our customers and prospective customers to whom we have a duty.

We focus generally on GM powertrain swaps into Jeeps, and with some expertise in classic Ford swaps into Jeeps, and some limited classic Dodge swaps into Jeeps, and other products as outlined in our Catalog. We are not likely able to help outside of this.

If you are exchanging parts from Jeeps to Jeeps, consider the truism that "the hardest parts to swap into Jeeps are Jeep parts" and that we probably don't have the answer to help.


Take an entertained moment and scan our Mythology vs. Actual Observances article. If one could condense four decades of Jeep conversion sense into one short article, then we think we've done it.

Your Details

It is most helpful to us for you to let us know as many relevant details about your Jeep and project as possible. Tire size and axle ratio (actual or intended, to the best of your knowledge), anticipated use or style of driving (trails? street? rocks? racing? all the above?) can be very useful.

Let us know your name, so we will know to whom we should respond. Your full name and your postal code are helpful if you are requesting components and would like a shipping estimate. Note our emphatic Privacy Policy if you are concerned about spam.

Requests for Instructions

Existing customers may request that product instructions be sent to them. Please have your invoice number and contact your salesman directly, or contact us through our phone system for express support.

Any other requests for instructions will be passed over.

Subsequent Messages

When responding back and forth with us, keep our previous conversations intact. A few bytes of text are cheap yet informative.

Your Email Provider

If you are mailing from an account that may have been implicated as a source of spam, it may not make it to us. If you've not heard from us in a few short days, you may wish to resend from an alternate account.

Note that our replies occasionally bounce back from certain mail services or those with full mailboxes. Hotmail, AOL and a few others have been problematic in some instances.

Not A Jeep?

Information requests for vehicles other than Jeeps are prioritized on our knowlege of them. Where our focus is so heavily on Jeeps, we will probably not have any helpful information about swaps in other vehicles.

Parts for the

SM465 Transmission

The SM465 is arguably one of the greatest four-speed transmissions ever built, and reconditioning one is a worthwhile project.

The Kit 

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.

Rebuild Requirements

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.

Other Components

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.
