When lifting your truck, 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 1.25 uni-ball bearing we’re able to gain wheel travel with a part that is considerably stronger and will last longer under extreme conditions. We build more caster and change the camber curve to correct geometry so the vehicle aligns correctly and improves driving characteristics and handling. Using the latest CAD/CAM engineering software we design these arms to the strictest standards using our FARO laser scan arm to model the OEM parts and frames. 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. Our in-house CNC machine shop makes all the machined parts including the uniball mis-alignment spacers from heat-treated stainless steel. We pride ourselves in producing the best parts available under our own roof and control.
