Heavy-Duty, Adjustable Upgrade for Front Suspension
These adjustable upper control arms are designed to replace your Jeep Wrangler JK’s factory arms with stronger, more flexible components. Ideal for correcting caster geometry after lifting, they deliver better articulation and durability. Built for 2.5"–4" of suspension lift, they come fully welded and ready to install. Each arm includes a 7/8" heim joint with 1/2" misalignment spacers, while the reinforced OE-style bracket is pre-drilled for 1/2" hardware—some models may require drilling to fit larger bolts.
