Steering Box Gusset Kit

Home / Steering Box Gusset Kit

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!

This my second purchase from Autofab. Very satisfied with the quality of my ls swap f150 mounts. They will have my business next time I build another ls swap f150.

If you need fiberglass for your truck this is the place to go. They also have other parts fabricated on site made in USA . The people who work here are great and very helpful. I can't say enough about the quality of their work and can't wait to see the shop for more parts. THANK YOU John and all the people who make Autofab what it is.

This is the second set of motor mounts that I've bought for my truck from autofab. The first set was for the original four-cylinder 2.3 engine and I drove that truck with my foot to the floor, as fast as I coud, over any bumps and jumps! If Anything and I only had one crack, on one of the motor mounts in the two and a half years that they were on there. I bought the new ones after I did the 5.0 swap and I have not been off-road yet but they are super high quality, good looking parts. I did have to modify them slightly because the headers that I have made the engine sit differently in the chassis. 10 out of 10 would recommend autofab motor mounts for your vehicle, especially if you're doing some hard off-roading.

Impressive welds on the motor mounts for my truck. Also have Autofab suspension parts and front bumper - all high quality stuff.
