• Questions? Stop scratching your head and contact us! We know our axles AND we’re here to help!
CONTROL ARM UPGRADE
• 4-6” LIFT: This much lift REQUIRES adjustable flexarms for caster angle adjustments.
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.
INNER AXLE SHAFT UPGRADE
• 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.
AXLE STUB UPGRADE
• 0-6” LIFT: High-quality aftermarket chromoly stubs are recommended, though the stock 2013-2017 JK outer axle stubs can be (re)used.
AXLE SHAFT TUBE SEAL UPGRADE
• 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.
STEERING SYSTEM UPGRADE
• 4-6” LIFT: Get the optimal set up w/ the JK 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).
