Valve Guides
VL-G3-C Bronze valve guide

We have updated our Bronze guide range to utilise a higher grade material, now being manufactured from Colsibro.

Bronze guides are very hard wearing & if you do have a problem with your engine which causes valve to piston contact the guide may distort slightly, but this is very unlikely to break. Whereas the valve guide made from iron will either crack & fall out at a later date causing a second failure or break into small particles imbedding themselves in the piston & head, so if your budget permits use bronze guides.
