These control arms are designed to be a direct replacement for your factorycontrol arms. They are a custom bore and width so that all factoryhardware can be used. We use a rebuildable flex joint with a zinc coatedchromoly housing and a delrin bushing. The bars are made of 1.75 x .120wall tubing with a weld in chromoly tube end. They have approximately3" of adjustment, 1" shorter than stock to 2" longer than stock so theycan be used on a lowered truck or on a mildly lifted truck. *If you desire a custom Powdercoat color, just note it in Custom Color Desired. This will add 2-3 week lead times *It is very common for factory bolts to be seized and need to be torched out and it is recommended you purchase new Camber bolts ahead of time. IT IS IMPORTANT THAT ALL JAM NUTS ARE TIGHT AND ARE CHECKED PERIODICALLYTO PROTECT THE THREADS OF THE JOINT. FIREPUNK WILL NOT BE RESPONSIBLEFOR ANY DAMAGED THREADS DUE TO JAM NUTS BEING LEFT LOOSE Please allow 1-2 weeks for Control Arms to ship if they need powder coated.
