Frequently Asked Questions

Can I mix Red Line 5W with other Red Line suspension fluids?

Yes — Red Line suspension fluids are formulated to be mixable, allowing you to create intermediate viscosities tailored to your specific dampener setup.

Will this reduce shock fade on my Harley?

Yes. Red Line's synthetic formulation significantly reduces shock fade and provides lower operating temperatures compared to conventional shock oils at the same viscosity.

What viscosity should I use?

5W is suitable for most V-twin applications. If you need a different viscosity, consult your shock manufacturer's specs or experiment by mixing with other Red Line grades.

How much do I need per shock?

Refer to your specific shock's service manual for the exact fill volume. A 16 oz bottle typically services one or two shocks depending on design.

Does this contain anti-wear additives?

Yes — Red Line includes anti-wear additives to help extend the life of shock seals and internal components.
