Poly Performance 2017+ Ford F250 / F350 SuperDuty Leveling Kit w/ 2.5" Fox or King Shocks

Kits Include:

• SYN-8663-25 - These Synergy Ford F250 / F350 front leveling springs lift the front of the truck 2.5”. These springs are progressively wound to provide a soft ride while increasing bottoming resistance.
• SYN-7675-02 - Synergy adjustable track bar is used to help center your axle after leveling the truck. This track bar significantly improves lateral stiffness over stock and is considerably stronger to hold up to the abuse of large tires and aggressive off road driving. Length is adjustable on the vehicle to make adjustments a breeze. The track bar is bent to clear most aftermarket differential covers at full bump.
• SYN-8612-24 - Synergy caster sleeves provided 2.4 degrees of caster and -1 to +.4 degrees of camber. When leveling your SuperDuty, the suspension geometry changes causing the factory spec caster to decrease. By installing these caster shims, the factory caster is restored to stock specifications. This helps maintain your steering return to center and overall factory steering feel.
• SYN-8673-01 - Synergy end link spacers are designed to add 5/8” of effective length to the stock sway bar end links. When adding longer than stock front shocks the end links will be pushed to their travel limits and begin to bind. These spacers add enough length to keep the end links from binding, allowing for extended travel shocks.
• SYN-8682-01 - Brake line relocation brackets keeps your brake lines from overextending while keeping factory lines so bleeding the brake system after installation is not needed.
• SYN-8657-01 - Synergy front bump stop spacers are designed to add 1” of space between the frame and bump stop cup. When adding longer than stock front shocks the shock will bottom out before the axle hits the bump stop on the frame. This puts high loads on the shock and frame where the shock mounts, leading to possible damage to the shock or the frame.

Your choice of 2.5" King or 2.5" Fox Performance Elite Shocks:

• King OEM performance shocks are tuned to provide your Ford with unparalleled levels of performance and ride quality. Each kit has been subjected to punishing real world testing to develop the optimal damping curve for your vehicle.
• King's optional new adjustable shocks give you more off-road control by affecting your high-speed compression. Each of the twenty levels of adjustment offers precise compression damping control ranging from very soft to very firm.
• Fox Performance Elite Series 2.5 Reservoir smooth body shocks give you enhanced ride quality and the control you need when heading off the pavement. They take their design from our Off-Road race shocks, so they've been thoroughly perfected in brutal conditions.
• Fox offers remarkable versatility and precise tuning with their external DSC adjuster. A simple twist of either two adjuster knobs allows 10 separate low-speed and 12 high-speed compression adjustments to quickly adapt the shocks to a variety of terrain any vehicle loads. DSC adjusters provide the ideal settings to tackle the trickiest of off-road obstacles or tame the twists and turns on the asphalt with the twist of a knob.

2020+ F250 / F350 came from the factory with a lower ride height than the 2017-2019 models. Also, Tremor packages came with a factory lift. These differences result in varying lift heights across models.

This kit is not compatible with Onboard Scales or Smart Hitch!
