Confirm Pioneer Tarp System Fitment

Use HR4719 as the primary replacement reference whenever possible. Pioneer tarp systems use different cylinders for the gantry, rack and arm-extension functions, so stroke length alone should not be used to select a replacement.

Before ordering, confirm the existing cylinder part number and tarp-system model. Also compare the mounting configuration, closed length, pin dimensions and hydraulic connections if the original part number cannot be verified.
