Fox Suspension Fluid, 20wt Gold, 1L

A Premium Suspension Fluid for Optimal Performance

Fox High Performance 20wt Gold Suspension Fluid is a premium, heavy-weight lower leg bath oil specifically engineered for the routine maintenance of Fox Racing Shox suspension forks and rear shocks. Designed to replace traditional lightweight fluids in modern Fox lower legs, this advanced formula minimizes stiction and optimizes seal performance.

Key Product Details & Specifications

• Brand & Name: Fox Racing Shox High Performance Fork Fluid - 20WT Gold
• Manufacturer Part Number: 025-03-072
• Volume Options: 1 U.S. Quart / 32 oz / 946mL (frequently labeled and sold interchangeably as 1 Litre in regional markets)

Core Functional Features

• Stiction Reduction:
  Formulated with proprietary friction-reducing molybdenum additives that coat internal slider bush surfaces, ensuring ultra-smooth fork sliding action under heavy trail loads.
• Foam and Corrosion Inhibition:
  Infused with specialized anti-foaming agents to maintain reliable consistency, alongside anti-corrosion properties that protect internal magnesium lower legs from moisture degradation.
• Seal Swell Protection:
  Explicitly balanced to interact safely with rubber wiper seals (e.g., SKF seals), promoting a slight, intentional seal swelling to lock out external trail dirt while keeping the lower leg bath oil sealed inside.

Critical Compatibility Notes

• Lower Leg Bath Only:
  This fluid is designed strictly as a lubricating bath oil for fork lower legs and air chambers. It is NOT to be used inside closed damper cartridges (e.g., FIT, GRIP, or Grip2 dampers), which require lighter 5wt or 4wt damper fluids.
• FIT & O/C Damper Configurations:
  Safe for all 34mm, 36mm, 38mm, and 40mm Fox forks using closed FIT or GRIP dampers.
• Open Bath Warning:
  Do not use this heavy 20wt fluid in legacy "Open Bath" Fox forks where the lower leg fluid is actively drawn directly into the damping cartridge assembly.

This suspension fluid is a trusted choice for maintaining the performance and longevity of your Fox Racing Shox components, ensuring smooth rides and reliable durability.
