Truck Trend Magazine recently dove into a 2-part driveway tech article showing the ins and outs of how to install the BDS 4.5" High Clearance Coilover Conversion System for the 2001-2010 Chevy/GMC 2500HD trucks. While this is a fairly involved install and one we encourage the use of a hoist and a skilled technician to complete, automotive journalist Jason Gonderman took on the challenge and the results are pretty awesome. He picked up an older 2002 Chevy 2500HD on the cheap due to some motor and mechanical issues and over the course of the last year has brought readers along as he gets the truck running sound mechanically and starts upgrading to breath new life into this 'ol LB7 Duramax.

With the mechanical dialed in, Jason turned his attention to the suspension and decided to scrap the 2-decade old torsion bar suspension in favor of the BDS 4.5" High Clearance Coilover Conversion System. This system offs plush on-road ride quality, a vast improvement over the original torsion bar IFS along with FOX's race proven shock technology to handle the rough stuff when Jason thrashes it out in the southern California desert. The lift system is based off the BDS 4.5" lift system with high clearance crossmembers, heady duty skid plates, beefy differential correction and ductile iron steering knuckles and combines it with FOX 2.5 factory series coilovers with the remote DSC reservoir, heavy duty frame and LCA mounting brackets and BDS high strength UCAs for strength and improved suspension travel.

Jason walks through the conversion and highlights man of the common "weak points" of the HD that get addressed along the way. With the lift installed, Jason bolted on a set of BDS Recoil traction bars to help lay down the LB7's power going to a set of 37" Nitto Trail Grapplers mounted on 18x9 XD Grenades.
