14 Bolt Disc Brake Conversion Kit (SRW)

Our disc brake conversion kit is the best conversion to eliminate the drum brakes on a full float 14 Bolt Rear Axle. The 14 bolt axle is common in Chevy / GM fullsize trucks from 1972 until today in the 3/4 ton and 1 ton range. Changing from drum brakes to disc brakes is easy, and all the parts you need to complete the conversion are included in this kit to get rid of those heavy drums brakes. These will only work on a 73'-87' axle the newer axles are hit and miss. To double check, measure from the 4 bolt mounting flange to the surface the wheel studs press up against (back of hub), should be about 4 11/16"


  • Requires steel wheel minimum 15" with a maximum 4" back spacing and larger aluminum wheels.
  • Fits 73-87 single rear wheel full float 14 bolt housings.
  • If longer studs are needed, usually dually studs are long enough or Dormin #610-301. Double check stud diameter, studs should drop freely into the rotor. DO NOT press studs into the rotor. If your hub has too large of studs you will need to drill the rotors to accept them. Be sure to have minimum 5/8" lug nut thread engagement
  • This application will NOT FIT DUAL WHEELS
  • This is for Full Float axles only, does not work on Semi Float
  • Rotor installs onto the backside of the hub!
  • Don't forget to re-bleed your brakes once you've installed your new conversion kit.
  • A Proportioning Valve is recommended, this will allow you to fine tune your front/rear stopping power bias. Your front axle should always do about 70% of the work.

Complete Kit Includes:

  • 1 Pair 14 Bolt Disc Brake Brackets with Grade 8 Bolts
  • 2 Weld on Brake Line Tabs
  • 2 Brake Line Clips
  • 2 Brake Calipers
  • 2 Hydraulic Hoses with 10mm Banjo Bolt Fittings
  • 4 New Brake Pads
  • 2 New Rotors

Ordering this product was easy, shipping was fast. This product functions properly and meets all of my expectations. Parts are of high quality and robust. I would recommend buying this product if you're tired of messing with drum brakes and want to lose some weight on the rear axle.
