Overview
Peak Chromoly Upper Control Arms – 2023+ Colorado ZR2, Canyon AT4X, Trail Boss, AT4
When lifting your truck, the factory upper control arms quickly become a weak link. Stock arms are prone to poor geometry, reduced strength, and over-articulation that puts stress on ball joints and bushings. Peak engineered a solution built specifically for off-road enthusiasts who demand reliability, handling, and long-term durability.
Engineered Geometry & Handling
Our Chromoly Upper Control Arms are designed with increased caster and repositioned pivot angles. This geometry correction restores proper alignment, improves high-speed stability, and ensures smooth steering response—both on-road and off-road.
Maximum Strength & Articulation
Instead of the weak OE ball joints, we use 1” stainless steel uniballs for superior articulation and load capacity. These uniballs are designed to withstand extreme suspension travel and heavy off-road abuse while maintaining a precise steering feel.
Maintenance-Free Dual Durometer Bushings
The latest Peak design evolution introduces dual durometer bushings at the inner pivots. This advanced system bonds rubber to a composite core with an integrated inner sleeve. The rubber layer absorbs small vibrations and trail chatter, while the composite core eliminates flex and prevents noise. The result: quiet, maintenance-free performance with no greasing required—ever.
