Our Camburg KINETIK sway-bar arms are available in many different lengths, one size doesn't fit all. They are machined in-house from billet 7075-T6 domestic aircraft quality aluminum for optimum strength and fatigue resistance. Not cheaper lower grade import materials. The arms are broached for large 1.5" 35 splines, not smaller 1-1.25" like many other companies do that can strip out. We use double pinch bolts to secure the arm to the torsion bar and pocket them to reduce weight without compromising strength. They are then bead blasted for a matte finish and anodized black with our logo laser etched. These are the same parts we use on our KINETIK Trophy Truck and 6100 builds. The optional sway-bar hardware kit includes Delrin pivot bushings that fits into 2" x.120w tubing, machined aluminum retainer end caps that are anodized black, 4130 heim tabs, Delrin spacers and Grade 8 hardware. The optional heim and spacer kit includes four FK JMX-10T 5/8" heims with jam nuts and 4 pairs of heat-treated stainless steel spacers. We can also source you the bungs and tubing if needed to build the link rods. Sway-bar torsion bars are also available in heat-treated aerospace 300M and are custom machined to your specs with various minor diameters for different spring rates based on your vehicle weight, sway-bar arm length, chassis width and driving style. We'll contact you for more information.
