  • 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!

Requirements & Recommendations:


  • 0-3" LIFT: This axle is a direct bolt-on upgrade! Although stock control arms will work at this lift height, aftermarket flexarms may be used if desired - highly recommended w/ a 3" lift.
  • Front upper (# 1252200) & front lower (# 1252000) TeraFlex JK Sport Flexarms will work w/ 2.5-3" lifts.
  • Front upper (# 1415520) & front lower (# 1415500) TeraFlex JK adjustable Alpine Flexarms will work w/ 2.5-4" lifts.
  • Front upper (# 1315520) & front lower (# 1315500) TeraFlex JK adjustable Alpine Long Flexarms will work w/ 3-6" lifts.


  • 0-6" LIFT: High-quality aftermarket axle shafts will enhance your set up. We recommend "œRCV" or "œTEN Factory" high-end shafts. Stock Rubicon axle shafts may also be reused.


  • 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.


  • 0-3" LIFT: The JK HD Tie Rod & Drag Link Steering Kit (# 1853900) will do the trick, though the stock steering system may be reused.


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