GSC P-D Toyota 3SGTE Exhaust Valve Guide .4378in OD .2360in ID 1.765in OL .003in Oversize - SINGLE

This exhaust valve guide from GSC Power Division measures .4378 inches in outer diameter, .2360 inches in inner diameter, and 1.765 inches in overall length. It's a .003 inch oversize part, meaning it's designed to fit into a slightly larger bore than a standard size guide, often used when reconditioning cylinder heads to ensure a snug fit and proper valve seating. This specific guide is intended for Toyota 3SGTE engines, a popular choice for performance builds where engine internals are critical.

When you're rebuilding the top end of your engine, especially a performance-oriented one like the 3SGTE, the precision of your valve guides is paramount. These guides control the movement of your exhaust valves, ensuring they seat correctly and seal the combustion chamber effectively. A well-made guide prevents excessive valve stem wear and helps maintain consistent valve timing and lift. GSC Power Division is known for producing well-built engine components, and this valve guide is no exception, offering a solid option for your engine build.
