"Skyjacker specifically engineered a progressive variable rate coil spring, distinctively a 2-stage dual rate long travel coil. Spring rate progression is from a first Flex Rate to a second Ride Rate. First Flex Rate stage of coil spring delivers a comfortable ride with ability to flex/expand during full articulation as suspension drops (full droop). This keeps coil springs seated in upper coil mount/bucket and tires in contact with terrain. Second Ride Rate stage only engages after compression past Flex Rate. Engineered with Wrangler's distinctive suspension handling characteristics, rear coils are side specific. Lower Links maintain proper driveline phasing and alignment. DOM tube steel links include installed pressed-in HD OEM style rubber bushings. Front and Rear Bump Stop Spacers keep suspension travel safely in check. Front and Rear Extended Length Sway Bar End Links allow full articulation as suspension drops (full droop). These end links include Skyjacker installed pressed-in HD OEM style rubber bushings. Front Adjustable Track Bar includes Skyjacker installed pressed-in HD OEM style rubber bushing at frame mount. Adjustable axle mount end is a 3/4-in. Heavy-Duty Rod End, Jam Nut and Alignment Bushings. A heavy-duty Rear Track Bar Bracket is included to center axle under vehicle to address new ride height and help keep factory roll center. Shocks are a key link in-between the chassis and your suspension. Their key role is to dampen out or control the terrain to keep your tires in contact with the terrain. ADX 2.0 has an innovative off-road race-inspired full-displaced valving system. The external remote reservoir separates nitrogen gas from oil with an Internal Floating Piston (IFP). IFP prevents gas and oil from mixing or foaming (cavitation). Nitrogen charged with Internal Floating Piston Technology = Quickest Shock Reaction Time Ever. From higher speeds to a slow advance, ADX 2.0 Adventure Series Remote Reservoir Shocks work."

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.
