SPC Performance 2021+ Ford Bronco Adjustable Upper Control Arms

Lifted trucks often experience a loss of caster, leading to tire wear and wandering at high speeds. These adjustable front upper control arms by SPC Performance are designed to address these issues. They enhance droop travel, improve drivability, and reduce tire wear. Additionally, they allow for adjustment of tire position within the wheel well. The arms are equipped with maintenance-free ball joints and xAxis™ sealed flex joints with bonded rubber sleeves, ensuring correct alignment angles while maintaining factory ride quality. The tubular steel construction offers strength and durability. These arms are sold in pairs and provide 80° of articulation in the ball joint and free pivoting cross-axis bushings, maximizing droop travel and articulation. With +1° of built-in caster and patented ball joint design, they provide ±2.0° of caster and ±2.0° of camber adjustment, allowing for proper alignment after lifting. The adjustment features also help improve tire clearance by moving oversized tires forward to minimize or avoid fender trimming.
