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.\u003c\/p\u003e\n\u003cp\u003eThese arms feature maintenance-free SilentSpin™ bushings that eliminate grease fittings and unwanted noise, along with heavy-duty Probearing 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 our shocks or other aftermarket shocks like King, Fox, Icon, and more.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSilentSpin™ bushings — no squeaks or maintenance\u003c\/li\u003e\n\u003cli\u003ePro 4 ball joints with sealed dust caps\u003c\/li\u003e\n\u003cli\u003eRebuildable, USA-made construction\u003c\/li\u003e\n\u003cli\u003ePrecision-welded 4130 chromoly tubing\u003c\/li\u003e\n\u003cli\u003eShipped preassembled for faster installs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUpgrade Your GM 2500 With Confidence\u003c\/strong\u003e\u003cbr\u003eBuilt 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.
