Designed, engineered, tested, and assembled in Colorado, SPC Performance adjustable upper control arms are loaded with impressive features. Improve suspension travel, handling, and tire wear while centering the tire in the wheel well for maximum clearance needed for oversized tires. Now 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. A Forged steel design provides the strength and durability needed for the most demanding environments. 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 gives more adjustability than any other arm on the market. Looking for rear lower control arms for your LC 100, consider #25955. Sold as pairs. US Patent No. 7,513,514.
Adjustable front upper control arms for the LX 470 AND LC 100 with chromoly tube steel construction, sealed modern architecture ball joints, and xAxis™ sealed flex joint joints in bonded rubber bushings
Product appearance and features may vary in the market as design changes, improvements and modifications are implemented.
