Bolt In Steering Box Brace for '73-80 GM 4WD Trucks

The straight axle GM trucks are notorious for frame cracks in the steering box mounting area.  This kit is designed to prevent that problem by eliminating the frame flex caused by increased steering loads like lifts, big tires and off-road use. 

The bolt-on (OK you do have to drill one hole) brackets triangulate the mounting area to stiffen it up before it breaks.  If the frame is already broken, you will need a weld-on repair kit before you install the brace. 

For hard use applications, we recommend using both the weld in kit and the bolt in Brace Kit, especially in 1/2T trucks and Blazers. "Hard use" could be defined as 37" and up tires in rock crawling or other demanding use.

Frame already broken? We highly recommend both the Weld on frame repair (to fix the broken frame) as well as the bolt in steering box brace (to keep the frame from breaking in the future).
