These are brand new items produced by Southwest Speed Inc. They replace the OEM parts and work perfectly with all connecting components in the correct application. This is the stock configuration, meaning when you turn the input shaft clockwise, the output shaft also turns clockwise; we do have the reversed version available here. For those custom aftermarket applications that require the reversed turning box.
This box is a direct replacement for the GM Manual steering box on the following vehicles, as well as hundreds of other GM vehicles. We also have thousands of other High Performance Parts in our store. We want you to have the parts as bad as you do.
