SG8 XL

The ultimate standard in heavy duty valve seats and guides.

Overview

SG8 XL-Smart is specifically designed for machine shops that build small to large cylinder heads within the heavy duty industry. From single cylinder to 24 valve six cylinder heads used in natural gas and mining, construction, and marine industries. Robins fixed pilot concept works the best to achieve ultimate chatter-free finish on valve seats within a few microns concentricity. Large 24 valve heads can be easily clamped and rolled full 360 degrees to allow work to be done on all sides of these cylinder heads.
