Peak Suspension Tubular Upper Control Arms – Chevrolet Colorado ZR2 (2017–2022)

Upgrading your suspension isn’t just about lift height—it’s about performance, strength, and reliability. When lifting your 2017–2022 Chevy Colorado ZR2, the factory upper control arms quickly become a weak point. Stock arms suffer from poor geometry, limited articulation, and reduced strength when pushed beyond their design. That’s where Peak Suspension Upper Control Arms come in.

Why Upgrade to Peak Upper Control Arms?

Our ZR2 tubular control arms are precision-engineered to correct geometry issues and deliver unmatched durability. Designed with increased caster and optimized pivot angles, they reduce stress on suspension joints and improve handling both on and off-road. The result is better alignment, smoother ride quality, and more precise steering control.

Instead of weak factory ball joints, we use massive 1″ ProBearing stainless steel uniballs, giving you maximum articulation and strength in demanding off-road conditions. For the inner pivots, we include Delrin bushings with grease fittings, ensuring long-term durability and easy servicing.

Each kit also features 17-4 stainless steel misalignment spacers and military-grade F911 hardware, delivering a rock-solid connection to the spindle. Every component is rebuildable or replaceable, meaning these arms are designed to last the life of your truck. Best of all, they arrive pre-assembled with detailed instructions for a straightforward installation.
