Requirements and Recommendations:

  • Below is a list of Requirements and Recommendations for TeraFlex axle housings as budget and build preference allows.

Control Arm Upgrade:

  • 0-3 Inch 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 inch lift.
  • Front upper (P/N 1252200) and front lower (P/N 1252000) TeraFlex JK Sport Flexarms will work w/ 2.5-3 inch lifts.
  • Front upper (P/N 1415520) and front lower (P/N 1415500) TeraFlex JK adjustable Alpine Flexarms will work w/ 2.5-4 inch lifts.
  • Front upper (P/N 1315520) and front lower (P/N 1315500) TeraFlex JK adjustable Alpine Long Flexarms will work w/ 3-6 inch lifts.

Axle Shaft Upgrade:

  • 0-6 Inch Lift: High-quality aftermarket axle shafts will enhance your set up. We recommend RCV or TEN Factory inch high-end shafts. Stock Rubicon axle shafts may also be reused.

Axle Shaft Tube Seal Upgrade:

  • 0-6 Inch Lift: Get serious with HD 0.5 inch wall seals (P/N 4354050) or keep it real with standard 0.25 inch wall seals (P/N 4354025). Stock seals may also be reused.

Steering System Upgrade:

  • 0-3 Inch Lift: The JK HD Tie Rod and Drag Link Steering Kit (P/N 1853900) will do the trick/ though the stock steering system may be reused.

Brake Upgrade:

  • 0-6 Inch Lift: Experience a notable difference w/ a TeraFlex Big Brake Kit (P/N 4303400 or P/N 4303420) or JK Big Rotor Kit (P/N 4303480 or P/N 4303490)
