Enhance Performance, Alignment, and Durability with SPC Adjustable Front Upper Control Arms [25460] Transform your truck’s drivability and tire performance with SPC’s adjustable front upper control arms. Designed for precision and durability, these control arms improve droop travel, alignment angles, and tire wear, all while maintaining factory ride quality. Key Features & Benefits: Maximum Droop Travel: SPC's innovative arm design provides improved clearance around the spring bucket, delivering enhanced articulation. With 80° of movement in the new maintenance-free ball joint and free-pivoting xAxis™ bushings, you get the droop travel you need for better off-road performance and handling. Restore Drivability & Tracking: Lifting your truck can throw off critical alignment angles like caster and camber. SPC’s control arms include +1° of caster built-in, and their patented ball joint design allows for 0° to +4° of caster and ±2° of camber. This adjustability ensures your alignment is back to spec, improving drivability and reducing uneven tire wear. Adjust Tire Position with Ease: Oversized tires? No problem. These control arms allow for adjustments in the arm and OE lower cams, enabling you to move tires forward in the wheel well. This feature helps avoid or minimize fender trimming while maximizing alignment angles. Technical Specs: Adjustment Range: Camber: ±2.0° Caster: 0.0° to +4.0° Installation Time: 0.8 hours per side
