Chevrolet Truck Suspension Competition - Chevy Runaround

First Annual 4x4 Truck Suspension Program

By Jerrod Jones, Photography by , John Lukar

Rough Country brought a unique No Torsion Bar Drop (NTD) kit out for us to play with for the weekend. The kit uses the common knuckle-replacement design and stayed within stock-style suspension parameters, but the company made a few impressive changes that set this kit apart. The torsion bars and crossmember were not dropped, and instead had a third pivoting arm and link that attached to the end of the torsion bar and the lower A-arm (the torsion bar usually slides into the lower A-arm). We really liked two of Rough Country's kit options; new billet upper A-arms and new CV shafts which could be adapted to almost any suspension kit, stock or not. The billet-aluminum upper arms were stock style but stronger, much more appealing, and able to take a triple shock setup. The CV shafts are something that we have been waiting for someone to make since Chevy came out with IFS trucks. With the triple shock setup, it felt like there was a bit too much valving to give a smooth ride in the rough dirt, but it made the on-road ride and handling incredible.
