CBM custom designed pulley kit. All pulleys are USA made, machined out of a solid piece of 6061 T6 aluminum and then chromed for extreme durability. Kit includes pulley for waterpump, alternator, belt tensioner, idler, power steering, and balancer cover. All hardware, bearings, and o-rings are included for complete installation. This is for LS series engines running a Camaro or GTO style water pump. This kit will work with on pump or off pump power steering reservoirs but must be specified at time of purchase. We also offer an over-sized pulley for the alternator if your application requires one. This pulley kit can be purchased individually if you do not need all of them!!! It also comes in a natural finish which is significantly cheaper.
