99880-73 Fork Oil

Spectro Oils of America provides this Heavy Duty SAE 40 fork oil, formulated to meet or exceed original manufacturer specifications, including OEM 99880-73. This lubricant features a superior viscosity index to minimize thinning and fading caused by heat build-up during intense riding conditions. It is engineered with anti-foaming additives and seal conditioners to protect against rust, oxidation, and stiction at the moment of direction change. By reducing friction and maintaining consistent damping performance across a wide temperature range, this oil extends the life of internal fork components. Sold as a single 1 quart (0.946L) bottle, it is an ideal choice for riders seeking stable and predictable front-end suspension response.
