Unique components for pre-1960s Willys and Jeep® enthusiasts

Siminoff JeeParts is dedicated to providing unique components for the serious pre-1960s Willys and Jeep® enthusiast.


Our most in-demand product is the TightSteer steering damper, a spring-loaded device that removes the free play common to early vehicles that have steering systems equipped with Ross® steering boxes.


We also offer a high-quality collection of early Willys catalogs and manuals that have been restored and reproduced to near-original appearance.


Your orders typically are processed the same day they are received. We ship worldwide using Priority Mail via the United States Postal System.

Watch TightSteer in action.
