Manganese-Bronze Valve Guides are your best buy because:
Our valve guides are manufactured completely in the
United States of America from the finest material
Our bronze material exceeds all original equipment
specifications and is at least more durable than any
currently competing U.S.A. produced bronze valve
Our bronze alloy utilizes hard filament shaped wear
particles, evenly distributed throughout the material,
and aligned along the length of the finished valve
guide. This type of metallurgical structure is
compatible with all modern valve stem materials.
Our bronze alloy has the highest
heat transfer rate of any bronze valve guide alloy:
More than 200% of nickel-aluminum bronze.
More than 200% of aluminum-silicon bronze.
Exceeds phosphor bronze alloys with 88% copper!
Inside diameter bore size and
concentricity of inside diameter bore to outside
diameter area dimensions are held to the closest
tolerances in the industry.
