Specs At A Glance

Good To Know

Q: Will this motor work if my top moves slowly rather than not at all? A: Slow movement often points to low fluid or a weak motor, so check fluid level and inspect the motor before replacing it. Q: Does the motor come with the pump and fluid lines? A: This listing covers the motor referenced as mp-4-oem, so confirm whether the pump assembly or lines are included before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
