Our Camburg upper arms are designed to address the limitations of stock upper arms when lifting your truck. By replacing the stock ball-joint with a uniball bearing, we improve wheel travel and durability under extreme conditions. We also enhance the vehicle's alignment and driving characteristics by adjusting the camber curve and incorporating larger and stronger FK 7/8" chromoly heim joints for additional camber and caster adjustment. The billet aluminum cover on top of the uniball prevents dirt and contaminants from entering. Our arms are meticulously designed using CAD/CAM engineering software and manufactured in-house with precision CNC laser cutting, bending, and MIG welding. They are then sandblasted and powder-coated for a durable finish. Our machined parts, including the uniball mis-alignment spacers, are made from heat-treated stainless steel in our CNC machine shop. The arms come with all necessary hardware and are designed for 1-2.5" of lift. They are specifically designed for ZR2 models and are made in the USA.
Given the multitude of factors such as wheel size, offset/backspacing, tire size, brand preferences, and suspension specifics, adjustments like trimming the plastic inner fenders or modifying the body mounts behind the front tires may be necessary to prevent tire rubbing.
Enhance your 2017-2022 Chevrolet Colorado ZR2's factory performance with upper arms specifically engineered for this off-road-focused platform. These Performance Heim/Uniball Upper Arms combine proven 1.25" FK uniball technology with precision heim joints, delivering race-proven capability while maintaining the ZR2's refined balance. The protective covers shield critical components from trail hazards, extending longevity during the aggressive off-road use the ZR2 was designed for. These arms correct suspension geometry compromised by lifts or larger tires, adding crucial caster to improve stability while optimizing camber curves for better tire wear and traction. The robust construction accommodates extended coilovers and increased wheel travel, unlocking performance potential limited by factory components. For ZR2 owners seeking to elevate their truck's already-impressive capability for desert running, rock crawling, or serious overlanding, these arms represent essential upgrades that transform good into exceptional. They deliver professional-grade performance at an accessible price point, proving you don't need unlimited budgets to build a truly capable mid-size off-road machine.
