Fitment Notes

  • Factory bump stops may need to be extended depending on the coils and shock combination used.
  • Due to the vast variances in weights and heights of vehicles and suspension combinations, Superior recommend you move your suspension in the full range of the shock absorber compression/rebound travel and consider coil bind. Also, check all areas for clearance issues.

  • Fig. 1 shows the Superior Arm deflecting only 4.1mm under load with real-world load points.
  • Fig. 2 shows the Competitor's Arm deflecting 24.91mm under the same load points and loads, almost the same as the width of the Arm itself.
