Adjustable Front Upper Control Arms – Alignment Correction for Lifted Trucks & SUVs

Engineered, tested, and assembled in Colorado, these SPC-style adjustable upper control arms are designed to restore suspension geometry on lifted trucks and SUVs. They improve caster and camber alignment, increase suspension travel, and reduce uneven tire wear—while also maximizing clearance for oversized tires.

Constructed from forged steel for unmatched strength, these arms provide superior clearance around spring buckets and are built to handle the most demanding conditions. The upgraded maintenance-free ball joint features a 25% larger stud than OE, with E-Nickel coating for exceptional corrosion resistance and up to 80° of articulation—more than any comparable option.

The patented ball joint design and xAxis™ sealed flex joints in bonded rubber bushings deliver smooth articulation, improved suspension travel, and reduced noise, vibration, and harshness (NVH). A fully sealed architecture keeps grease in and contaminants out, ensuring long service life with no maintenance required.

Key Benefits & Features:

• Corrects caster and camber alignment on lifted vehicles for improved drivability and reduced tire wear.

• Built-in positive caster eliminates “wandering” and unstable steering after suspension lifts.

• Adjustable range (with OE adjusters) allows precise tire placement and maximum clearance for oversized tires—without frame or fender modifications.

• Forged steel construction for maximum strength and durability.

• New ball joint design: 25% larger stud, corrosion-resistant coating, and 80° articulation for strength and flexibility.

• Sealed ball joint and polymer race ensure smooth, quiet operation and extended service life.

• xAxis™ sealed flex joints improve suspension travel and reduce NVH.

• Front Adjustment Range: Camber ±2.0˚ / Caster 0˚ to +4.0˚.

• Sold as a pair (1 set required per axle).

• US Patent No. 7,513,514.

Why You Need These Control Arms:
When a truck is lifted, factory alignment geometry changes—causing poor handling, uneven tire wear, and clearance issues. These adjustable control arms correct alignment angles, restore steering stability, and allow oversized tires to fit properly without unnecessary trimming.

Upgrade today for stronger alignment correction, smoother handling, and the clearance your lifted truck or SUV needs.
