20-20330 KPMI, intake valve guide. C630 bronze. STD

For the high-revving V-Rod engines produced between 2002 and 2017, heat management is critical. These Kibblewhite intake valve guides are machined from C630 bearing bronze, a specialized nickel-aluminum-bronze alloy designed for high-performance and racing environments. This material is chosen for its ability to rapidly transfer heat from the valve to the cylinder head, keeping things cool under pressure. These standard-sized guides have a 0.440-inch outside diameter and a 0.2340-inch inside diameter. Whether you are doing a stock refresh or building a track bike, these bronze guides offer the toughness and thermal conductivity required for the liquid-cooled Revolution engine.
