Rinehart Story

The company started in a garage with borrowed tools and a makeshift workbench fabricating exhaust collectors for NASCAR driver Dave Marcis in the early 1990s. This humble beginning later led to performance parts that revolutionized stock car racing and V-Twin motorcycles. Today, the name Rinehart carries a legendary and unrivaled reputation for proven performance.
