2011-2021 Jeep Grand Cherokee WK2 Long Arm Upgrade Kits

Serious lift on the WK2 runs into geometry limitations that short-arm setups simply can't overcome, and that's the problem 2011-2021 Jeep Grand Cherokee WK2 Long Arm Upgrade Kits exist to solve. Moving to longer control arm geometry corrects the caster and pinion angles that compress-spring platforms develop when the lift gets beyond the range factory arm length can accommodate.

 

Long arm conversion kits for the WK2 involve more than just swapping arms — crossmember relocation or replacement typically comes with the territory, and the investment in fabrication complexity is what makes these kits a serious platform upgrade rather than a bolt-on. Builders planning a long arm conversion should confirm the kit includes proper geometry correction for the specific lift height being targeted, since generic long arm designs don't always account for the WK2's independent rear suspension characteristics.
