Skyjacker re-engineered the Super Dutys suspension via an impressive 4-Link Conversion. Replace your OEM radius arms with integrated radius arm drop brackets plus upper and lower adjustable control arms. Formed from 2-inch OD x 0.250 wall DOM tubing, both pairs of control arms are adjustable Flex Links. The adjustability allows proper caster settings to improve handling. Flex Links have a forked clevis end at the lower axle mount. The upper bracket mount has 1-1/4 in. forged rod end with steel encased rubber bushing. Drop brackets lower the rear mounts at the frame to maintain the correct caster specifications for proper alignment. Specifically engineered for Super Duty F250 4WD Diesel motors, these 2-Stage Variable Rate Springs deliver a smooth controlled comfortable ride. First Flex Rate stage delivers a comfortable ride with the ability to flexexpand during full articulation. Second Ride Rate stage only engages after compression past Flex Rate: resulting in a smoother ride. An ultra heavy-duty track bar relocation bracket captures the front crossmember on both sides to prevent movement in this critical high-stress area and to keep the axle centered. Front sway bar links realign sway bar. Drop Brackets reposition front bump stops. Front brake line brackets and braided stainless steel brake lines correct and reposition the brake lines. A heavy-duty steering stabilizer relocation bracket and Hydro steering stabilizer included. A 5-inch rear block and U-bolt kit and Softride(R) add-a-leaf delivers a more level stance. Carrier bearing lowering kit corrects driveline angles to eliminate driveshaft vibrations. Shocks are a key link in-between the chassis and your suspension.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.


    Donald Wojnar
  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.


    Adam Cranston
  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.


    Bryce Budd
  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.


    William Brunell
  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
