Power in Precision
In 1928, founder Joe Sunnen introduced our manual cylinder hone to help garages touch up their cylinders for a more perfect finish. To this day, the design principles from that first product have guided the success of our complete line of modern honing machines, tools and abrasives.
Our engine building technology:
- Produces an exceptionally round and straight bores
- Meets or exceeds original factory accuracy for alignment, roundness and size
- Corrects distortion caused by warpage, cap stretch and engine wear
Our solutions are designed for a variety of engine building applications, such as:
- Connecting rod reconditioning
