Description Dirt King 4130 Upper Control Arms – Built to Solve Real Problems If you drive a 2023+ Canyon or Colorado ZR2/Trail Boss and you're ready for a suspension upgrade, these 4130 UCAs are for you. We made them to tackle the exact issues we kept running into ourselves—squeaky bushings, joints that need constant attention, and geometry thrown off as soon as you add a lift. Whether you're daily driving, overlanding, rock crawling, or chasing desert trails, these UCAs handle it all. These arms feature maintenance-free SilentSpin™ bushings that eliminate grease fittings and unwanted noise, along with heavy-duty Probearing Pro 4 ball joints for high articulation and superior strength. The ball joints are sealed to block out debris and finished with anodized caps. Built to maintain proper alignment from 0–3" of lift, these arms also add roughly an inch of down travel compared to stock, a must-have when paired with aftermarket coilovers like King, Fox, Icon, and more. Why Go Dirt King? SilentSpin™ bushings — no squeaks or maintenance Pro 4 ball joints with sealed dust caps Rebuildable, USA-made construction Precision-welded 4130 chromoly tubing Shipped preassembled for faster installs Upgrade With Confidence Built and tested in the USA, these 4130 UCAs are engineered for the long haul—perfect for rigs that work hard on weekdays and explore even harder on weekends. It's the last set of upper control arms you'll ever need.
