Info

Easily install 11" rotors and 1978-88 GM Metric calipers to your 1937-48 Ford passenger car style spindles with no machine work needed. This disc brake kit is great for street rods based on 1932-1948 Fords. For lightweight cars like T-buckets or early roadsters, we recommend the Wilwood kits. This front disc brake conversion kit works well with bolt-on steering arms. The 11" diameter rotors have the GM wheel bolt pattern of 5 x 4-3/4". Calipers have 7/16"-20 inlets.

  • Fit modern GM style disc brakes to your 1932-48 Ford spindle equipped hotrod
  • Designed to be used on 1932-48 Ford street rod-type builds
  • 11" diameter rotors provide plenty of stopping power
  • 5 x 4-3/4" bolt pattern to fit¬†behind many¬†Chevy bolt patterned wheels
  • GM metric style calipers are easily serviced and maintained for years of dependable service

Notes

Installation Note:  If utilizing the later Ford 'Square Back' style spindle, it will require minimal modification (removal of approximately 1/8" of material from the spindle) to clearance the caliper bracket.  The early Ford style 'Round Back' spindle will not require this additional modification.  Due to the numerous types of bolt arm steering arms that can be utilized, installer provided steering arm bolts applicable to the specific steering arms may be required as provided by installer.
