GSC P-D Toyota 2JZ Manganese Bronze Exhaust Valve Guide +.001in Oversize OD - Single

This listing is for a single GSC Power Division exhaust valve guide for Toyota 2JZ engines. It's made from manganese bronze and is +.001 inch oversize on the outside diameter. This guide is designed to replace worn or damaged original equipment guides, helping to ensure proper valve sealing and engine performance.

Manganese bronze is a solid material for valve guides because it offers good wear resistance and lubricity, which is important for the high temperatures and stresses found in exhaust ports. Being +.001 inch oversize means it's intended for applications where the cylinder head bore has been machined to accept a slightly larger guide, often during an engine rebuild to achieve a precise fit. This is a single component, so you'll need to order one for each valve you're replacing the guide for.
