Pioneer Valve Guides
Valve Guides are machined fit according to proper I.D., O.D. and length.
Cast Iron Guide with Spiraled I.D. - Designed for the economy minded, this design retains oil for proper lubrication of the valve stem.
Bron-El® Valve Guide - This design is also made of cast iron, but the I.D.'s spiraled phosphor-bronze liner can withstand the high temperatures of today's hot running engines. Bron-El® guides usually last 3 to 5 times longer than cast iron guides.
Manganese Bronze Valve Guide - Simply the best anti-seize, low-friction valve guide available. With today's engines consistently running at elevated temperatures and burning unleaded fuel, you need the self-lubrication protection this valve guide provides.
