Oil - 240cc - RFF 5 wt - Full Suspension LLC

240cc Torco RFF 5 wt Racing Fork & Damper Fluid

Professional-grade suspension fluid packaged by Full Suspension LLC in a convenient 240cc service bottle.

Torco RFF 5 is a high-viscosity-index synthetic blend suspension fluid designed for cartridge and damper applications. Its light viscosity makes it an excellent choice for modern MTB suspension dampers and damper-side lower-leg lubrication applications.

Technical Viscosity

Torco RFF 5:

  • 16.00 cSt @ 40°C

  • 5.05 cSt @ 100°C

  • Viscosity Index: 285

  • Synthetic blend

  • Light red color

Unlike nominal "5 wt" ratings, which can vary considerably between manufacturers, cSt provides the actual measured kinematic viscosity of the oil.

Recommended Applications

Excellent for suspension applications requiring a light-viscosity hydraulic/damper fluid, including:

  • FOX GRIP damper applications

  • FOX GRIP X

  • FOX GRIP X2

  • FOX GRIP SL

  • FOX GRIP damper-side lower-leg bath

  • Fork cartridge damper service

  • Open-bath and cartridge suspension systems

  • Other suspension dampers requiring a light approximately 16 cSt fluid

FOX currently specifies a light 4 wt suspension fluid for many GRIP-family damper and damper-side bath applications. Torco RFF 5 provides a high-quality aftermarket fluid option for technicians looking for a light-viscosity suspension fluid.

Why RFF 5?

Torco RFF Racing Fork Fluid is engineered specifically for suspension use rather than being a general-purpose lubricant.

Its proprietary additive package provides:

  • Advanced anti-friction protection

  • Anti-stiction additives for smooth suspension movement

  • Anti-wear protection

  • High viscosity index for consistent damping

  • Anti-foam additives

  • Seal-conditioning additives

  • Oxidation protection

  • Corrosion protection

  • Excellent temperature stability

  • Long-term component protection

Built for Damper Performance

Fluid viscosity directly affects the way oil moves through damper pistons, ports, bleed circuits, and shim stacks.

At 16.00 cSt @ 40°C, RFF 5 is a true light-viscosity suspension fluid well suited to modern low-friction damper systems where consistent oil flow and temperature stability are critical.

Convenient 240cc Service Size

No need to purchase a full liter of suspension oil for a single service.

The 240cc bottle provides enough fluid for many fork damper, lower-leg, and suspension service applications while reducing leftover oil and shop waste.
