Those of you that have ’73 to ’87 Chevy or GMC full-size pickups or up to 1992 Blazers and Suburbans, are probably fully aware of the steering box problems these rigs typically have. It’s not the box itself but the way it is mounted to the frame lends itself to major flexing caused by bigger tires, wheels, and especially lockers. The frame rail can crack and loosen the bolts, and then the box falls off at the most inopportune time.
Other companies offer frame repair kits and they will reinforce the mounting area but it spaces the box out for the thickness of the repair, and does not attack the flexing problem itself. Autofabs’ brackets go to the source of the problem and triangulate the mounting of the steering box to the front cross-member to effectively stop the flexing which causes the frame to crack in the first place!
