This is a door operator (torsion balancer) assembly for a Whiting roll-up truck door.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It includes a 90-inch shaft and two torsion springs (one road-side, one curb-side) made from .187-inch wire, each 29 inches long, that counterbalance the weight of the door. It is typically replaced when the springs weaken, break, or the shaft wears out, restoring smooth manual or assisted lift operation on dry freight trailers.
