Knieriem Racing has been in business for 40 years doing business as Harry's Auto Parts & Machine Shop for the first 35 years. We take pride in being perfectionists in everything that we do.

Harry Knieriem started the business, and Glenn Knieriem purchased it from Harry in 1973. Glenn's son, Tim Knieriem, started working in the shop at a young age learning the machine shop business. Tim eventually came to work here full time in 2002.

The Knieriems are active racers and know what it takes to build a quality engine for street rods, boats, pull trucks, round track and more especially drag racing. In addition, Knieriem Racing builds stock engines as well. They will do the machine work and let you build the engine or they can do a complete rebuild.

Knieriem Racing will work closely with you, the customer to achieve the results wanted.
