Oct 29 - We are getting pretty close on last inventory for this year for a few products, (2) Ford & GM Core kits done your way. We have just (2) 4 link kits left in HD only, and a handful of trackbar kits. Once these are gone there will be no further production until next year, so plan accordingly. We are taking some time here at the end of the year to work on the site, product development, and video editing. Thanks for stopping by!

Description

This is a universal bolt-up manual transfer case shifter for the 4L80 transmission found in GM trucks and vans. The kit is optimized for universal application and can be modified to fit easily into 4x4 van conversions, swaps, and custom builds. This kit has been tested with NP241, NP261, NP263 and other similar transfer cases successfully including electronic t-cases with manual conversions. 

Our design bolts directly to the side of the transmission and provides a spot to clip the transmission shifter cable into. All necessary hardware is included. We recommend ordering with a shifter boot and ball for the easiest installation.

How it works

This setup is built with the installer in mind, we can break it into sections. For people that need visual representation, scroll further to see the installation instructions to wrap your head around it. 

Here are the kit sections:

1) Main Bracket - This bolts to your 4L80 using existing bolts. It seats snug while  providing a pivot point for the rotating assembly on either side of the bracket (top of the triangle).
2) Rotating Assembly - This can be installed without cutting anything so you can determine the path of your lever through the floor. The geometry reduces stress on joints and provide an easy throw for the lever. The DOM center tube has a grease zirc, sleeved poly bushings to isolate vibration and a clean stub serves to mount the union you'll connect the upper lever to. 
3) Upper Lever - This pre-bent lever can be rotated in the union for additional adjustability and clearance pre or post-install. 

This Upper Lever comes 3 ways.
1) Pre-finished version: tested for all van applications, turn-key with coating, and pick your ball appearance.
2) Unfinished version with ball: The unfinished version comes raw and with an additional union that can be used to cut down the overall length, add bends, or further modify your application while still maintaining the fully finishd lower assembly. Typically the upper union can be buried under the shift boot. Lever comes pre-studded for included ball.
3) Unfinished version without ball: Specify "no-ball", and you're on your own to figure out how to mount a ball to the 5/8" stock, this may suit highly customized builders.

4) Connecting Rod - This threaded hardened steel rod comes with (2) FK heims and is cut to length. You'll basically mock up the assembly as described so far, then determine where you want the upper lever to fall in forward and rear positions then just cut the rod to that length and bolt it up.

It's easy to punch out the existing stud on your t-case side lever and pop in our grade 10 1/4" hardware to make everything fly. If you need a new t-case lever we build them to order for your specific case, so call on that.
