SPC Performance Alignment Caster / Camber Control Arm

Precision Alignment Engineering: SPC Performance Caster & Camber Control Arms

When a suspension lift or performance lowering job throws your caster and camber angles out of spec, stock replacement parts rarely provide enough adjustability to bring things back in line. That's exactly the problem that SPC Performance — a Colorado-based company recognized as a world leader in alignment parts and tools — has spent decades engineering solutions for. Their Alignment Caster / Camber Control Arms represent the pinnacle of that expertise, combining patented technology with heavy-duty construction to restore proper geometry no matter how far a vehicle has been raised or lowered.

What Sets SPC's Control Arms Apart

At the heart of SPC's adjustable upper control arm lineup is their patented ball joint design, which unlocks a range of 0 to +4° of caster correction and up to ±2° of camber adjustment in a single drop-in replacement arm. This is critical for lifted trucks and SUVs, where raising ride height negatively affects caster and camber angles and can lead to handling characteristics like wandering, accelerated tire wear, and poor steering returnability.

SPC arms are equipped with their proprietary xAxis™ sealed flex joints housed in bonded rubber sleeves. These cross-axis joints provide a free pivot for droop and misalignment, meaning that OE caster and camber adjustments won't bind the joint — while the rubber isolation retains factory-level Noise, Vibration, and Harshness (NVH) values. The result is an arm that simultaneously corrects alignment angles and preserves the ride quality drivers expect.

Built for the Demands of Lifted Trucks and Performance Applications

SPC builds their control arms using chromoly tube and forged steel construction — the same material choices proven in circle track, road racing, and Formula Drift competition. Each arm is designed, engineered, tested, and assembled in Longmont, Colorado, and features improved clearance to navigate the spring bucket with a full 80° of articulation in the ball joint for maximum droop travel. The adjustable ball joints also receive a hex chromate-free finish that is validated against a 700-hour salt spray test, offering superior corrosion protection for off-road and daily-driven vehicles alike.

Beyond lifted trucks, SPC's control arm range extends to lowered cars, classic muscle cars (including early Ford Mustang, Falcon, and GM A/F/X-body platforms), and dedicated motorsport builds. Whether you're dialing in a slammed street car or correcting geometry after a 4-inch suspension lift on a Toyota Tacoma or GM truck, SPC has application-specific arms engineered for the job.

Restore Drivability and Tire Life

Incorrect alignment isn't just an annoyance — it accelerates tire wear, stresses steering components, and compromises safety. SPC Performance's adjustable caster/camber control arms allow owners and alignment technicians to place tires precisely where they need to be in the wheel well, maximize clearance for oversized tires, and return all alignment angles to factory specification. Sold in pairs, these arms are a direct remove-and-replace upgrade with no cutting or fabrication required.
