These are the popular Delco 21SI and 22 SI units found on many types of heavy duty applications. We have purchased a number of Chrome units and need to move them out. These brand new alternators have a beautiful chrome finish, produce 165 amp, and we are letting them go below cost to make room for other inventory. They are a 1 wire design (needing only the battery output cable) so they can be used for a large number of installations.
These alternators are sold outright (no core required) Please email your questions concerning applications to us and we will respond quickly.
