Construction & Design:

The xAxis Front Lower Control Arm is constructed from high-quality 3/16" wall round DOM (Drawn Over Mandrel) steel tubing, chosen for its exceptional strength and resistance to bending or deformation under heavy loads. The round tube design not only adds structural integrity but also features a shape that minimizes interference with large, aggressive tire treads, making it ideal for off-road enthusiasts running oversized tires.

At the heart of the design is SPC’s xAxis sealed flex joint technology. These joints are engineered to provide smooth, bind-free articulation by allowing controlled twisting motion between the frame and axle. The sealed design protects the joints from dirt, moisture, and debris, ensuring long-lasting performance even in harsh off-road environments.

Installation & Fitment:

Installation of the SPC Performance xAxis Front Lower Control Arm is straightforward due to its direct-fit, stock-length design. It replaces the factory lower control arms without requiring modifications to the suspension or frame. The dual-threaded adjuster and jam nut system simplifies caster and pinion angle adjustments, allowing precise tuning to maintain proper alignment and driveline angles after installation.

This control arm fits a wide range of Jeep Wrangler models from 2007 to 2018, including Rubicon, Sahara, Sport, Sport S, and Unlimited trims, as well as the 2018 JK series. It is compatible with both stock-height and lifted suspensions, making it a versatile upgrade for many Jeep owners.
