TKX/4WD Transfer Case ‘Hi-Boy’ Bracket Assembly

Are you considering a Tremec TKX 5-Speed conversion for your divorced transfer case Hi-Boy truck but wonder how to make the 4WD shift lever work?

Here ya go!


Comes with:
All mounting and lever hardware.

Supplied nylon bushing length will have to be sanded by the customer to fit the lever.
Modified T-case levers will have to be restored to fit the supplied nylon bushing diameter.


The installation images show a before and after shifter location coming from the original transmission to the new Tremec TKX transmission.
The 4WD shift lever maintains the same position providing your lever position is approx. 12.60″ from the front of the transmission case
The shifting lever picks up the front-shift location on the TKX transmission and sets it right next to the 4WD Transfer Case Lever.
