Red Line Synthetic Oil Heavyweight Suspension Fluid is a 30wt formulation designed for many Harley-Davidson® and American V-Twin motorcycle forks and rear shocks that have not been re-valved. This suspension fluid helps maintain consistent damping performance in demanding riding conditions while supporting reliable operation across a wide range of temperatures.
Its advanced synthetic formulation delivers superior shear stability to help the fluid retain its intended viscosity during repeated suspension movement. Reduced fade and lower operating temperatures help promote consistent fork and shock response, while the anti-foaming properties support smooth, predictable damping performance. Excellent lubricity helps reduce friction and protect internal suspension components from wear.
Use this Red Line Synthetic Oil suspension fluid for compatible motorcycle fork and rear shock applications requiring a heavyweight 30wt fluid. It is well suited to many Harley-Davidson® and American V-Twin motorcycles using original, non-re-valved suspension components. Always verify the motorcycle manufacturer’s service specifications and suspension requirements before installation. This product is supplied in a 16 U.S. fluid ounce container and is identified by manufacturer part number 91142 and vendor part number 91142.
