APE valve guides are designed to take the abuse of today's
modern high horsepower engines. They are made from special silicone
bronze alloy to resist wear and heat. No other valve guide that you can
buy will out-perform APE guides. Fact is, we supply our guides to nearly
all of the top cylinder head shops. Major police departments use them in
their patrol bikes which see severe use. Our guides are precision
machined with the bores finished to size. They are designed fit lower in
the head to clear high lift cams, and use APE seals or factory OEM
seals. Sold in complete sets.
