The Cognito uniball sm series upper control arms, FK 1.25” uniball joints are included as well as new crush sleeves and polyurethane bushings built with a modified uniball angle to eliminate travel limitations of the ball joint in lifted applications. Ample droop travel is required for good ride quality and all suspension components to last and work properly. The allowable droop travel is also improved with the design of these arms.


  • Corrected uniball joint angle
  • Added caster
  • Polyurethane bushings
  • Semi gloss black powder coating
  • Also fits AT4 & Trail Boss models
