SPC Performance 04-17 Ford F-150 Front Adjustable Upper Control Arms

These adjustable front upper control arms are designed, engineered, tested, and assembled in Colorado. They feature forged steel construction, sealed modern architecture ball joints, and xAxis™ sealed flex joint joints in bonded rubber bushings. These control arms improve suspension travel, handling, and tire wear while centering the tire in the wheel well for maximum clearance needed for oversized tires. They are equipped with maintenance-free ball joints and free-pivoting xAxis™ sealed flex joints in bonded rubber sleeves for correction of alignment angles and restoration of factory ride quality. The forged steel design provides strength and durability. SPC adjustable control arms have improved clearance to get around the spring bucket and a full 80° of articulation in the ball joint. When trucks are lifted, caster and camber angles are affected that can lead to poor handling characteristics such as ‘wandering’. SPC control arms have positive caster built-in for lifted vehicles to restore alignment angles and drivability. The patented ball joint design allows the tire to be positioned correctly in the wheel well, and additional adjustment in the OE lower arms can maximize placement for oversized tires to avoid fender trimming. If replacement lower adjustment cams are needed, see part #86250 or #86252. Sold as pairs.
