How to choose suspension fluid

Fresh suspension fluid keeps your fork and shock smooth, supple and consistent. Using the right fluid is key.

Follow the spec

Use the fluid type and weight your fork or shock manufacturer specifies.

Damper oil

Controls damping. The wrong weight changes how fast your suspension moves.

Bath oil

Lubricates seals and bushings in the lowers, like Fox Gold or Maxima Plush.

Weights vary

A 5wt from one brand may not match another. Stick with recommended products.

Dropper fluid

Hydraulic dropper posts like RockShox Reverb need their own specific fluid.

Service intervals

Regular lower leg services keep suspension feeling new. Check your manual.

Find seals and kits in suspension service kits, plus suspension tools and shock pumps.
