GSC P-D Mitsubishi 4G63T Manganese Bronze Exhaust Valve Guide +.003in Oversize OD - Single

Manganese bronze is a strong material for exhaust valve guides, and this GSC Power Division guide uses it for your Mitsubishi 4G63T engine. It's made to be a +.003 inch oversize outer diameter, which is helpful if you're re-sleeving or machining your cylinder head to accommodate a slightly larger guide. This single guide is specifically for exhaust valves, where temperatures are higher and wear can be more aggressive.

When you're rebuilding the top end of a 4G63T, getting the valve guides right is crucial for proper valve sealing and longevity. This guide is well-built from manganese bronze, a material known for its good wear resistance and ability to handle heat. The oversize OD means it's intended for applications where the cylinder head bore has been opened up to match, ensuring a snug and secure fit. This is a single guide, so you'll need to order the correct quantity for your engine's needs.
