A vibration isolator (401) includes an upper housing (403) and a lower housing (405); an upper reservoir housing (427) defining a upper fluid chamber (407); a lower reservoir housing (429) defining a lower fluid chamber (409); a piston spindle (411) resiliently coupled to the upper housing with an upper elastomer member (413), the piston spindle being resiliently coupled to the lower housing with a lower elastomer member (415); an inertia track (419) having a tuning passage (421), the inertia track (419) being removably coupled to the piston spindle (411); and a tuning fluid (423) disposed within the upper fluid chamber, the lower fluid chamber, and the tuning passage. The vibration isolator (401) cancels vibratory forces at an isolation frequency, the isolation frequency being at least partially dependent upon a size of the tuning passage (421).
