GM has updated its V8 performance engines and launched the new Gen V LT1 direct injected engine as a replacement for the very popular LS series of engines. This new accessory drive bracket installation kit allows the use of our popular & reliable Holley LS accessory drive bracket systems to be installed on the new LT1 engine. This drive system has incorporated an upgrade to the conventional looking and central located LS water pump which works in conjunction with an OEM LT1 truck harmonic balancer. This application fits all LT1 style engines (except the dry sump and supercharged applications).This new installation kit includes spacers for the LS style brackets, water pump spacers, a solenoid re-clocking retainer ring, re-routed front harness, and all hardware.
