Drive Junky 5-LT4-003 - Gen V LT4 Street Monster Front Accessory Drive system Without A/C

There have only been a handful of production engines in history that have eclipsed the 650 plus HP mark, and the new generation GM LT4 is one of them. This is the most powerful production engine GM has EVER sold period. If you are going through the trouble to adapt one of these into your car, it makes no sense to not go with the best quality you can find in aftermarket parts to run the accessories. This Drive Junky kit fits the LT4 and is a direct bolt on for the LT4 wet sump. (call if you're running the dry sump). Countless hours of R & D have gone into what you see on these pages.

The supercharger belt on this system runs only one thing, the supercharger. The belt length is short, and runs a gates heavy duty automatic tensioner, similar to Drive Junky's very limited production Magnuson and Whipple blower builds. The tensioner can be seen under the custom machined cover on the front of the engine. This drive system simplifies and shortens the belt run that the factory engines run in Corvette and Cadillac CTS-V configurations. The blower drive and accessory drive belts feature Gates’ new RPM Racing belt made from a High-modulus, low-stretch polyester tensile cord with the strength to transmit load more accurately with less vibration. All accessories run on a separate belt behind the blower drive. The “rear” accessory belt drive is the same drive with some modifications that is on Drive Junky LT1 kit, so see those kits too for additional info or layout questions.

IMPORTANT NOTE: The LT4 crate engines are shipping from GM in one of two configurations as far as accessories go. They come bare with only the harmonic balancer, or bottom crank pulley, and the water pump. This system picks up from there and includes everything else you need, including the addition of a power steering pump. Like the LS, there are some differences with the water pump and balancer installed on the engine from GM which depend on the vehicle they were designed to be installed in. There is a Cadillac CTS-V and a Corvette variation. The water pumps differ and the belt distance from the face of the block to the belt is a bit further on the CTS-V version. This system is a direct bolt on for the wet sump CTS-V variant to give the option of different alternator setups (the water pump has a built in bracket on the Corvette version which limits those choices, as well as packaging concerns and best belt wrap, layout, etc. If you have another “version” we can accommodate those engines, please call on those. Here is an example part number of one of the correct style LT4s for this system: GM 19355404

Most of the engines going out now ship this way from GM, especially with Connect & Cruise packages when they are ordered as wet sump. Once again, if you don’t have this version call us.
