CMB Uniball Upper Arms

When lifting your 11'-19' Silverado 2500 HD, 11'-19' Silverado 3500 HD, 11'-19' Sierra 2500 HD, 11'-19' Sierra 3500 HD, the stock upper arms become the limiting factor and hold back your suspensions performance. Our Camburg upper arms address these issues and more. Replacing the stock ball-joint with a larger Made in the USA FK uniball bearing with a military grade PTFE internal liner, we're able to gain wheel travel with a part that is considerably stronger and allows for higher angle misalignment. Machined in-house, the uniball is adapted to the spindle/knuckle using model specific spacers machined from heat-treated stainless steel, for a precision fit without the need for drilling or modifications. Manufactured in-house, we have the tubes CNC laser cut and bent, then are MIG welded in precision fixtures before sending out to be sandblasted and powder coated. We pride ourselves in producing the best parts available under our own roof and control. Step by step instructions, with all the necessary hardware, ensure a successful installation for your next off-road adventure. Performance Series Uniball Upper Control Arm Kit.
