• 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 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.
AXLE SHAFT UPGRADE
• 0-6” LIFT: High-quality aftermarket axle shafts will enhance your set up. We recommend “RCV” or “TEN Factory” high-end shafts. Stock Rubicon axle shafts may also be reused.
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/ a 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.
