Vehicle Brief Fabtech-3.5" UNIBALL UCA KIT
Market Description This high quality GM 3500HD lift kit offers an increased ride height for enthusiasts looking to run a 35in tall tire with enhanced offroad capabilities. The stance of the vehicle will become more level front to rear for an aggressive look. The factory GM upper control arms are replaced with Fabtech's Uniball Upper Control Arms that provide additional wheel travel with an extra degree of caster compared to stock UCA's. They are constructed of the finest material with .120in wall 1.50in OD 4130 Chromoly tubing. High quality 1in FK Stainless PTFE lined Uniball bearings are utilized in place of ball joints. These super stout Control Arms are designed for increased longevity in rugged offroad conditions while providing a more positive on road feel. Fabtech's forged torsion bar keys replace the factory units and allow for additional ride height adjustment to work in conjunction with the new upper control arms. The rear receives 2in blocks and U-bolts to help level the stance of the vehicle. Fabtech offers their Stealth shocks with this suspension. They are a sealed monotube shock that has a Nitrocarb piston rod for corrosion resistance and resist rock chipping. They will provide a great highway ride with good offroad damping capacity. This 3.5in HD lift kit comes with high quality components that add strength and reliability to the vehicle while giving it a commanding presence. Fabtech UCA's eliminate factory upper ball joint with super strong 1in ID Stainless Steel American Uniball for increased suspension strength. Additional caster is built into Arms for enhanced align ability with oversized tires. 1.50in OD .120in wall 4130 Chromoly tubing reduces flex found in stock arms for more positive road feel. 17-4 Heat treated Uniball pin fits into factory ball joint taper without modification to the spindle for easy return to stock feature. 17-4 Stainless steel misalignments for proper clearance of large Uniballs throughout the travel range. Billet Uniball cap keeps dirt and
