Requirements & Recommendations:

  • Below is a list of Requirements & Recommendations for TeraFlex axle housings as budget and build preference allows.
  • Questions? Stop scratching your head and contact us! We know our axles AND we're here to help!


  • 4-6" LIFT: This much lift REQUIRES adjustable flexarms for caster angle adjustments.
  • Front upper (# 1415520) & front lower (# 1415500) TeraFlex Adjustable Alpine Flexarms will work w/ 2.5-4" lifts.
  • Front upper (# 1315520) & front lower (# 1315500) TeraFlex Adjustable Alpine Long Flexarms will work w/ 3-6" lifts.


  • 0-6" LIFT: REQUIRES aftermarket inner axle shafts to handle the additional power. TeraFlex offers 34.19" passenger side axles (# 304136) & 19.11" driver side axles (# 304120). These shafts MUST be used w/ 2013-2017 JK axle U-joint.


* 0-6" LIFT: High-quality aftermarket chromoly stubs are recommended, though the stock 2013-2017 JK/JKU outer axle stubs can be (re)used.


* 0-6" LIFT: Get serious with HD 0.5" wall seals (# 4354050) or keep it real with standard 0.25" wall seals (# 4354025). Stock seals may also be reused.


* 4-6" LIFT: Get the optimal set up w/ the Complete High Steer System w/ HD Tie Rod & Drag Link Flip Kit (# 4391000) or save a little w/ the HD Tie Rod & Flipped Drag Link Kit (# 1853905). For tighter budgets, the High Steer Knuckle Kit (# 4390879) will provide the necessary steer height w/ your stock steering components. The factory steering system may also be reused.


* 0-6" LIFT: Experience a notable difference w/ a TeraFlex Big Brake Kit (# 4303400 or # 4303420) or Big Rotor Kit (# 4303480 or # 4303490).
