Description
Part number 983-02-143 is the FOX® Factory Race Series 2.0 ATS Steering Stabilizer for 2017-2026 Ford F-250 Super Duty and F-350 Super Duty 4WD trucks, featuring an 8.11 inch travel Adjustable Through Shaft design with an external piggyback reservoir.
IMPORTANT: This stabilizer fits 0 inch lift applications only and does not fit trucks equipped with the Tremor off-road package. Confirm your truck’s lift height and trim before ordering, as FOX® does not list an alternate ATS stabilizer part number for lifted or Tremor-equipped Super Duty trucks in this listing batch.
Conventional steering stabilizers create a push or pull sensation as the driver turns, since fluid inside the stabilizer body is displaced unevenly in one direction versus the other. The FOX® Factory Race Series 2.0 ATS Stabilizer solves this with an Adjustable Through Shaft architecture that eliminates shaft fluid displacement through the stabilizer’s full range of travel in both directions, delivering consistent, predictable damping regardless of steering direction.
An external piggyback reservoir increases fluid capacity and uses an Internal Floating Piston (IFP) to separate the shock oil from the nitrogen gas charge, preventing cavitation and maintaining consistent damping performance even under repeated, aggressive steering inputs.
Driver-tunable performance comes from an external adjuster with 24 clicks of adjustment, allowing the stabilizer’s damping feel to be dialed in for a range of driving styles and terrain. The stabilizer body is 2.0 inch impact extruded and CNC machined from 6061-T6 aluminum with a hard-anodized finish for corrosion resistance, while internal components are black-anodized, CNC-machined 6061-T6 billet aluminum. The 5/8 inch shaft is hard chrome plated and heat-treated alloy steel, backed by a redundant sealing pack with main, wiper, and scraper seals, and is covered by the suspension product warranty from FOX®.
