ReadyLIFT is excited to announce that we have developed an all-new adjustable heavy-duty front track bars for the 2017-2021 Ford Super Duty 4WD Trucks with 0 to 5 inches of front lift. Our all-new 77-2006 (2017-2021) Super Duty track bar is extremely strong and provides a wide range of solutions to remedy many of the common issues with lifted or leveled F250/F350 4WD trucks. The 77-2006 track bar is constructed from thick 1.5"-3/8-wall DOM tube steel with CNC-machined 4140 Chromoly ends. On the frame side of the bar we include a threaded forged housing with a maintenance-free heavy-duty bushing that screws into a twin-pinch on-truck adjuster. This design allows you to adjust either ReadyLIFT track bar to the desired length on the vehicle.?On the axle side, our 2017-2020 #77-2006 track bar features a heavy-duty Moog ball joint with a corrected angle that works excellent on stock, leveled or lifted (up to 5") trucks. This exciting new front track bar is engineered to be a direct bolt-on replacement for Super Duty trucks with 0"-5" of lift. For trucks with 6"-8" of lift, these track bars will work when using a track bar relocation bracket which is found in our ReadyLIFT 6.5" and 8" lift kits.
