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 larger 1.25 uni-ball bearing, we improve wheel travel and durability under extreme conditions. We also adjust the caster and camber curve to correct geometry, enhancing driving characteristics and handling. Our arms are meticulously engineered using CAD/CAM software and our in-house CNC machine shop produces all the necessary machined parts. The arms are made from thick .156" wall round tubing, laser cut and CNC bent, and MIG welded in precision fixtures. They are then sandblasted and powder-coated for a durable finish. The arms come with polyurethane frame pivot bushings with grease-able zerk fittings and FK 1.25" PTFE-lined uniballs pre-installed. All necessary hardware is included for installation. The arms are designed for 1-3" of lift and also fit '07-20 Tahoe/Yukon SUVs (without electronic controlled suspension). Please note that some factory wheels may require a wheel spacer and we recommend aftermarket wheels with a zero offset for optimum performance and fit. The factory droop stop must be removed from the frame mount. Our Camburg upper arms are proudly made in the USA and are the best available for your truck.. 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..
