SPC Performance 25620 Isuzu/gm Adj Arms (pair)

The SPC Performance 25620 adjustable upper control arms are a heavy-duty, remove-and-replace solution for Isuzu D-Max and second-generation Chevrolet Colorado trucks that have been lifted beyond their factory alignment range. Sold as a pair, these cast replacement arms restore proper caster and camber geometry, eliminate suspension bind, and maximize droop travel for lifted and off-road applications.

Alignment Correction:

• Provides 0° to +4° of caster adjustment to correct wandering and restore straight-line stability after a lift
• Delivers ±3° of camber adjustment to bring wheel angles back within specification
• Arms include +1° of positive caster built-in, giving lifted trucks a head start on alignment correction
• Used in combination with OE lower cam adjusters, these arms allow maximum alignment range and the ability to reposition oversized tires forward in the wheel well to minimize or eliminate fender trimming

Increased Droop Travel:

• Redesigned arm geometry provides improved clearance around the spring bucket during droop, eliminating arm-to-frame contact on lifted trucks
• Maintainable ball joint features an oversized ball and allows more than 80° of articulation, ensuring the joint never binds at full droop

Long-Life Components:

• Maintainable ball joint with oversized ball is designed for durability in demanding off-road environments
• SpecRide bushings feature free-pivot design to eliminate bushing failure common in high-travel suspension systems
• Engineered to correct alignment angles while preserving factory ride quality

These arms are a direct bolt-on, remove-and-replace design — no cutting, welding, or modification required. Sold in pairs. Patent No. US 7,513,514.
