These worked great to replace the lift motors on my lift chair for my van. I am inba wheelchair and the drivers seat in my van lifts up, turns to face the passenger seat and also slides back and forward to help with my transfer to the drivers seat. These motors worked good to do the lift part. They are a little slow compared to tge original ones which is why I gave them 4 stars. They are silent while working so that's a plus and a negative, since they are a little slower, it's hard to know they are working for a second after I flip the switch. They do lift the seat and me up with no problem at all. I am 6'1\" 200lbs. So they have to lift me and close to 100lbs in seat and the seat base and lift mechanism.
