Start your PRI show at the finish: the Sunnen finish


Find out what race winners have known for nearly 90 years - winning starts with bore honing equipment from Sunnen. More than 15 different parts in an engine are improved with honing, and Sunnen gives you the equipment, gages and knowhow to finish for the win. Whether it's cylinder bores, crank bores or rod/pin bores, our exhibit at PRI (Booth #5101) will have it all, including the SV-20 cylinder honing machine that has taken the industry by storm. Check out our lineup at PRI:



SV-20 Cylinder Hone 

Combines Sunnen's linear servo-stroking technology with power and capacity to drive multi-stone diamond tools for OEM-quality bore geometry. See a video of the SV-20 in action here (video is at the bottom of the page).



Gives production rebuilders a new level of control for achieving precise cylinder geometry, surface finish and crosshatch parameters. A servo-cradle automatically indexes V-type blocks from bank to bank, while the spindle automatically indexes from bore to bore.



SV-10 Cylinder Hone 

The industry standard for cylinder diameters from two to eight inches for all types of blocks, with a user friendly control and diamond honing capability.



THE game to beat for finishing rods and other parts with bores up to 6.5 inches. Automatic size control, Automatic stone-wear compensation and a host of features and options.



LBB-1660 Manual Rod Hone 

The low-cost system for precision rod reconditioning and pin fitting.





Aligns crank and cam bores in minutes with minimal stock removal to preserve thrust faces and oil-seal grooves.
