Making Sure This Is Your Jack

Body length is the fixed outer body measured with the jack retracted. Plate position is measured from the closed end of the body — positive toward the foot, negative past the closed end. Measure both before ordering.

Build history:

• Body length was 29" before June 2023 — older units use a shorter body
