Kit installs 11" diameter GM mid-size disc brakes on your machined 1949-54 Chevy car spindles, 1941-59 Chevy pickup spindles, or Speedway '49-'54 Chevy-style spindles. Stock spindles will require minor machine work.
NOTE: This kit will not work with stock '49-'54 Chevy steering arms installed on stock '49-'54 Chevy car front ends. Kit is designed for street rod dropped tube front axles using 1949-54 Chevy-style spindles and flat plate steering arms. Kit will not work with "straight" tube axles as the caliper will contact the axle tube before sufficient turning radius is completed.
