ABOUT US

Proper Parts was founded in 2006 by Alex Porti when he couldn’t find a replacement Power Seat Transmission for a 1981 Rolls-Royce Silver Spirit.  As a result, he engineered and built a robust Power Seat Transmission to replace the original.  Since then, we've sold well over a thousand transmissions for certain model years of Rolls-Royce and Bentley, and many models of General Motors from the late 1970s to the late 1980s. In addition, we offer the accompanying Power Seat Motor fully rebuilt.

Our current product line also includes newly designed ECU’s that control power seats and mirrors in Range Rover, Rolls-Royce, and Bentley. We've sold close to a thousand ECU’s around the world since 2011. Other parts are in production.

We manufacture quality products that cannot be found anywhere else with exceptional warranties and a fair price.  All of our parts are designed and manufactured in the United States.  Proper Parts is a privately owned unaffiliated company. We sell directly to restorers, dealers, and individual car owners in the USA and Internationally. 

With over 25 years of experience restoring Rolls-Royce and other classic cars, we have the troubleshooter's perspective and are always developing new parts. We aim to build better than new.
