1964- 1974 GM A, F, X Body Power Front Aluminum Tri-Power Disc Brake Conversion Kit with Drop Spindle - 13" Rotors - A123-14DS


Convert your GM A, F and X Body front brakes to Tri-Power caliper disc brakes and get the stopping power of a 6-piston caliper in a compact format.

Our exclusive Tri-Power calipers give the flexibility of using any 17-inch wheel with 2 inch drop spindles.

With this design, you increase braking performance while reducing caliper weight for better ride quality, and eliminate corrosion problems.

Simple bolt on instructions and all the parts you need to convert from drum to disc brakes.

  • For O.E. non-power cars only.
  • Bolts to stock drum brake spindle.
  • Tri-Power 3-Piston aluminum calipers with stainless steel pistons and E-Coated brackets. This caliper uses C5 Brake pads and weighs 50% of typical cast iron big brake calipers.
  • Kit includes disc brake master cylinder and 9 inch booster, adjustable proportioning valve, high performance low dust pads, forged 2” drop spindles, DOT braided stainless flex lines and all hardware
  • Calipers, brackets and proportioning valve 100% MADE IN USA
  • Turbo slotted rotors with Xtra Life plating standard, optional Big Bite cross drilled and slotted rotors with Xtra Life plating.
  • NOTE: Included booster will not bolt in place of factory booster on O.E. power brake vehicles. If you have an O.E. power brake vehicle, use our non-power kit since the master cylinder in that kit will bolt to your factory booster.

Please note that the calipers in this kit are coated with a clear anodize finish. Upgrade to red or black calipers for an additional cost.
