1981 to 1991 Chevy and GMC 4×4 Cracked Frame Repair Kit

Bolt-in frame reinforcing kit stops frame flex which causes cracks. Fits 81-87 Chevy and GMC K10, K20, and K30 4X4 trucks. Also fits 81-91 4X4 Blazers, Jimmys, and Suburbans. Cracks in the frame must be repaired prior to installation. The Autofab steering box gusset kit will keep the frame from cracking again. 2 wheel drive Blazers and Jimmys will need the SBGK2wd for their reinforcements.
