  • Front Upper Frame Mounts for Bearing Style Coil Overs
  • Bolts onto backside of upper cross-shaft frame mount to locate (welding after this is recommended)
  • Converts upper shock stud mount to a bearing style upper shock mount (1? wide x 1/2? ID)
  • Does away with the sloppy stud / rubber bushing type upper coil over mount
  • Does away with the flattening of the rubber bushings that tends to happen over time on coil-over setups
  • More precise suspension movement is the direct result (no more rubber bushing slop to account for)
  • Uses any 1? wide x 1/2? ID upper shock mount. We recommend 4? Stroke shocks for most applications (Note:? AFCO shocks require their ?Z? Rod upper shock mount for vehicles wanting a low front ride height ? Click here ->?319-FADCOBB)
  • Includes (2) Grade 8 shock bolts / nylocks, LH upper mount, RH upper mount, (2) travel limiter bolt pad brackets
