Vehicle Fitment

The Fox 2.5 Performance Series Coilover Shock (SKU: 983-06-103) is designed for specific aftermarket applications, typically for 4WD vehicles with 0-2 in. lift. Due to its universal design, fitment varies by vehicle and suspension setup. Common applications include: 

• Dodge/Ram 1500 4WD: 2009–2018 (Gasoline engines only, excludes MegaCab, EcoDiesel, and Air Ride models). 
• Jeep Wrangler JK: 2007–2018 (with 1.5–3 in. lift, requires aftermarket upper control arms). 
• Toyota Tacoma 4WD: 2005–2023 (with 0–2 in. lift, verify with suspension kit).

Note: Fitment depends on vehicle configuration, lift height, and aftermarket suspension components.

Performance That Outshines the Competition

The Fox 2.5 Performance Series Coilover Shock is engineered for drivers who demand precision and durability. Its DSC adjuster allows fine-tuning for varied terrains, from high-speed desert runs to low-speed rock crawling, outperforming competitors’ shocks that lack such versatility. The remote reservoir ensures consistent damping by increasing oil and nitrogen capacity, preventing fade during extended off-road use—unlike standard shocks that overheat or lose performance. The zinc-plated steel body and aluminum components dissipate heat four times better than conventional materials, ensuring longevity in harsh environments. Customer reviews highlight its “precise control” and “comfortable ride,” making it ideal for both off-road adventures and on-road stability. Compared to brands like Bilstein or Rancho, the Fox 2.5 offers superior adjustability and race-proven technology, making it the top choice for performance enthusiasts.
