Purchasing an expensive piece of equipment is one thing. But being overcharged for service parts is another. This is why we offer a quality crankshaft polisher with a lifetime warranty. Since 2014 our polishers have polished a wide variety of crankshafts. Kart Racing, Ultralight Aircraft, and Drag and Dirt Track Racing Engines just to name a few. A company in California purchased 4 of our polishers to finish hydraulic rams after the grinding process.
