SPC Performance Ford Ranger Front Upper Adjustable Arms (PR)

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 tubular frame and Forged steel adjustment nose design provides the strength and durability needed for the most demanding environments. SPC adjustable control arms have impro ved 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 r estore alignment angles and drivability. The patented ball joint design gives more adjustability than any other arm on the market, use it in combination with cam adjusters on the lower arm to maximize tire clearance and minimize the need for frame mods. Use SPC #63020 to adjust thrust angle, replace OE lower cams with #86220. Sold as pairs. US Patent No. 7,513,514.
