Fox 5W Blue Shock Absorber Oil For Factory Series Or Performance Series Shocks 1 Quart Bottle


Description
A common question that we get asked is "how much shock oil do I need to buy?". This tool will help you determine how much oil to buy PER SHOCK. It only ESTIMATES the amount of oil you'll need to purchase, NOT how much oil you actually put into the shock. It does not compensate for the seal head, hose, shaft, bypass tubes or other parts in the shock that all take up volume. Distance above the IFP is the length before the piston bottoms out. Some shock builders completely bottom out their IFP and some builders set their IFP an inch or more before being bottomed out to have some oil in the reservoir chamber.

Originally Fox used blue 5w shock oil in all their standard shocks and JM92 red 7w "racing" oil in their race series shocks. Now all modern Fox shocks come with JM92 red 7w oil as of about 2014.
If you have an "emulsion" shock without a reservoir, you fill the shock body to Fox's specifications and measure from the edge of the body down to the fluid.
If you have a shock with a reservoir, you fill the shock body to Fox's specifications and measure from the edge of the reservoir down to the piston.
