Dodge Dana 70 Disc Brake Conversion Kit 81-93

Dodge Dana 70 Disc Brake Conversion Kit

Complete Disc Brake Swap for Dodge Dana 70 SRW Axles

This disc brake conversion kit is built to eliminate the heavy and hard-to-service drum brakes found on 1981–1993 Dodge Dana 70 single rear wheel (SRW) axles. It includes everything needed to complete the swap and delivers better stopping performance, easier maintenance, and significant weight reduction—perfect for off-road applications.

The kit uses weld-on brackets and mounts the rotor behind the hub. It fits standard 15" steel wheels with a maximum 4" backspacing. All components ship ready to install, including rotors, calipers, pads, and lines. Not compatible with dually axles or bolt-on drum assemblies.
