1 gallon jug or 5 gallon pail FOX JM92 Shock Oil
Recommended replacement for all manufacturers oil to increase consistency and performance. Some MFG’ers not listed below may use a different viscosity so be aware of that prior to changing. As stable as this oil is you most likely wouldn’t know the difference in everyday driving. In performance applications you will notice better consistency through a much larger range of temps vs a standard oil like King.

Not sure how much to order? Use this simple math
.004(gal/inch) x Shaft Stroke(in) x (Body OD(in) x Body OD(in) x 3.14)/4 = gallons.
For a 2.5x10 shock its .004x10x2.5x2.5x3.14/4 = .196 gallons per damper. This will get you estimated gallons needed with extra since it uses the OD, not ID of the shock to account for resi oil too. Better to have extra than not enough when doing a service.
