GM 4x4 Conversion Essentials Kit

Sold out

***Current lead time on this component kit is 7-10 days from order-to-ship***


This kit comprises the over-the-counter components necessary to complete our standard 4x4 torsion bar conversion on most 2003-2022 GM 2500/3500/4500 series vans. These components are required for the conversion and we have organized them into one tried & tested kit. 

Many of the parts for our 9.25 IFS torsion bar conversion can be sourced for less or with used parts, however, we have combed through a good deal of the variations with brands and how that impacts compatibility with strictly our design, and these are the ideal brands/models of parts to work with.

You'll find our pricing on these components is competitive, and they come neatly on a pallet to your shop/door without having to scavage the internet to save $20/part and pray they show up punctually and in one piece.

Van Side - 2010-2022 Chevrolet Express 2500/3500/4500 series vans with 4.8 and 6.0 gas engines only.
