PGR is definitely without a doubt the best gearbox repair company in the U.S, We have been useing them for quite sometime now they do all of our major gearbox rebuilds. I recommend PGR with great confidence for all your gearbox repairs and needs.

thumb Amanda Costello

Very glad i chose precision gear to do the rebuilding/repairs on our 3 davis standard gearboxes, their state of the art workmenship and lead time was outstanding. After we received the gearboxes back we went ahead and sent out our 15 ft extruder screw to them for repair. And just like the gearboxes the repairs were absolutely perfect and exactly what we needed! I recommend these guys to anybody!
