Engineered to Military-Spec Standards

ICON 5WT Shock Oil is formulated to U.S. military-spec aviation hydraulic fluid standards, a specification that demands chemical stability, predictable viscosity behavior, and resistance to breakdown under stress. For an off-road shock absorber that sees repeated high-cycle loading on rough terrain, fluid that holds its properties over time means the damping tune you set up stays closer to the tune you actually feel on the trail.

Wide Temperature Performance

The 5WT formulation delivers outstanding low-temperature fluidity, so shocks respond predictably on cold-weather runs rather than sluggishly pushing through thick, stiff fluid. Across a wide operating temperature range, the oil maintains stability: performance does not degrade as shocks heat up during extended technical driving or high-speed desert running.

Anti-Wear Protection Extends Service Life

Exceptional anti-wear properties reduce internal component wear inside the shock body. Keeping wear low during routine service intervals helps extend the working life of seals, pistons, and valving. Those components are far more expensive to replace than the fluid itself.

Who This Is For and Isn't

ICON 5WT Shock Oil suits anyone servicing or rebuilding ICON shock absorbers (V.S. 2.0, 2.5, and 3.0 Series) or other shock brands that call for a 5-weight hydraulic fluid. The one-gallon volume is appropriate for shop use or servicing multiple shocks in a single session.

This oil is a shock-absorber service fluid only. It is not a differential fluid, gear oil, or general-purpose hydraulic fluid for other vehicle systems. Compatibility with non-ICON shock brands is broad but not universal; confirm the fluid specification for your specific shock model before use.

Common Questions

Which ICON shocks is this oil compatible with?

ICON 5WT Shock Oil is compatible with all ICON shock absorbers, including V.S. 2.0, 2.5, and 3.0 Series units, as well as many other shock brands that specify a 5-weight hydraulic fluid. Confirm your specific shock model's fluid requirements before servicing.

What standard does this shock oil meet?

ICON 5WT Shock Oil is formulated to U.S. military-spec aviation hydraulic fluid standards, which govern viscosity stability, low-temperature fluidity, and anti-wear performance across a wide operating temperature range.

How much oil does one gallon cover?

One gallon is the container size; the quantity needed per shock rebuild depends on the specific shock model and cylinder volume. Consult ICON's service documentation for your shock model to determine how many rebuilds one jug will cover.

Is this oil safe for use in cold climates?

ICON 5WT Shock Oil is formulated for outstanding low-temperature fluidity, meaning it flows and provides consistent damping response in cold conditions rather than thickening in ways that would slow shock response.
