Construction & Design

These control arms are built from heavy-duty 1 1/2 inch solid steel bar, ensuring exceptional rigidity and durability under demanding off-road conditions. The use of a 2 inch Johnny Joint rod end provides a high degree of articulation, reducing binding and improving suspension travel. The formed steel fork and jam nut design on the opposite end allow for secure length adjustments and maintain alignment integrity. A semi-gloss black powder coat finish protects the arms from rust and environmental damage, extending their service life.

Installation is straightforward for experienced mechanics and off-road enthusiasts familiar with suspension upgrades. The adjustable threaded ends allow for length changes without removing the control arms from the vehicle, simplifying pinion angle tuning after lift installation. These control arms are a direct fit for 2007–2011 Jeep Wrangler models with the 3.8L V6 engine, as well as 2012–2018 Jeep Wrangler JK models equipped with the 3.6L V6 engine.
