Skyjacker re-engineered the F350 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 RB style rubber bushing. Skyjacker's legendary Softride(R) technology engineered processes achieve maximum wheel travel, ride quality and extends the long-lasting life of the coil spring. Skyjacker specifically engineered this Variable Rate Coil Spring for the F350 Super Duty 4WD Diesel to deliver a smoother ride. An ultra heavy-duty track bar relocation bracket captures the front crossmember on both sides to prevent movement in this high-stress area and to keep the axle centered. A drop pitman corrects steering angle. Lowering brackets realign the front sway bar for maximum sway control. Drop spacers reposition the front bump stops. Front brake line extension brackets correctly reposition the brake lines. A heavy-duty steering stabilizer relocation bracket corrects and enforces the stabilizer connection. A 4.5-inch rear block and U-bolt kit, E-brake relocation brackets, bump stop spacers, rear braided stainless steel brake line extensions and rear exhaust hanger brackets are included. Front and rear damper capacity enhanced with ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks. ADX 2.0 has a race-inspired full-displaced valving system. Nitrogen charged with Internal Floating Piston Technology = Quickest Shock Reaction Time Ever.

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.
