The J20 rear disc brake conversion was developed because our J20 customers simply would not take “no” for an answer.

The brackets are machined from 3/8" A36 hot rolled steel plate. Sharp edges are deburred before sand blasting and powdercoat. The kit includes a set of brackets with 6061 aluminum spacers and Grade 8 mounting hardware.

What else will you need?
• (2) Rotors (1975 -1988 GM 3/4 ton 4x4 truck front)
• (2) Calipers (1975 -1988 GM 3/4 ton 4x4 truck front)
• (1) Set of brake pads (1975 -1988 GM 3/4 ton 4x4 truck front)
• (2) Soft brake lines (braided stainless steel lines available)
• (2) Banjo bolts
• Brake fluid
• Common Tools

If you want to keep your cable e-brake substitute '78 El Dorado rear calipers instead of the GM front calipers. Our brackets will work with both calipers.
