KSP PERFORMANCE F-150 Aluminum Upper Control Arm for 2-4 inch Lift | Adjustable Front A-Arms

Overview

Meet the KSP PERFORMANCE F-150 Aluminum Upper Control Arm, a front suspension component built for strength, precision, and reliability in lifted setups. By using a one-piece forged aluminum body, the arm stays lighter than traditional iron while delivering high rigidity under load. The absence of welded joints reduces common failure points, and the use of T6 aluminum provides natural rust resistance, even in winter and wet conditions. Each arm undergoes magnetic particle inspection during production to verify structural integrity and consistency.

Designed for lifted trucks

If you’re running a 2-4 inch leveling lift, these arms help correct ball joint angles and provide a broader range of motion. The result can be a more balanced front end with improved articulation for street driving and off-road adventures. Expect a front suspension feel that stays composed as you navigate rutted roads or uneven trails.

Durability and materials

The bushings use premium polyurethane to withstand temperature swings better than rubber, while a thoughtful groove design helps lubrication reach critical surfaces. The combination contributes to steadier steering feedback and reduced noise. The ball joints use a zinc-nickel coated pin and protective dust boots plus exclusive covers to minimize debris intrusion, supporting longer service life in tough conditions.

Serviceability and maintenance

A greasable socket allows you to refresh lubrication and flush contaminants, helping to sustain performance over time. The assembly emphasizes metal-to-metal contact with precision CNC-machined tolerances, offering robust, reliable performance without unnecessary complexity.

Compatibility and fitment notes

The kit is compatible with 2004-2020 F-150 models (not for Raptor), and 2006-2022 Expedition and Navigator models. Note that conservative stock wheels with ET44 offsets may rub the control arm; you may need a 1.5" spacer or a 0 offset aftermarket wheel to ensure proper clearance.
