This is a shallow header operator assembly (also called a balancer assembly) for roll-up trailer doors.
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 uses a heavy-duty torsion spring to counterbalance the door's weight, making it easy to lift and close. Shallow header applications are designed for trailers with limited overhead space, such as certain dry vans and reefers. You typically replace this assembly when the door becomes hard to lift, doesn't stay open, or the spring breaks. The unit includes the spring and hardware; the shaft may need to be ordered separately depending on your door width.
