Little known fact: Muscle up manufactures the chassis for Schwartz. Muscle Up is owned by former NASCAR driver Rich Bickle. Rich purchased a circle track chassis business a number of years ago (I think it was called Pathfinder) They branched out into muscle car chassis and Jeff Schwartz began marketing them under his name. I think the development of them began before Bickle got involved. I am not sure if it was Jeff's design/idea or the former owner of the manufacturer.

Jeff has been able to use his car building business and frequent magazine coverage to promote the Schwartz chassis brand much more effectively than Bickle can.

Not that uncommon to have someone else manufacture a product and brand it as your own. Several DSE products are (at least originally were) manufactured by an engine shop that I am very familiar with.
