Holley is offering up a new accessory drive system for LT engine applications, including the LT4 and the LT5. The system is designed to eliminate the headache of mixing and matching pulleys and belts when swapping in a new LT engine, and moves the front drive accessories closer to the block to provide a considerable increase in available clearance.
As a reminder, the supercharged 6.2L V8 LT4 is the same engine found in high-performance models like the C7-generation Chevrolet Corvette Z06 and Chevrolet Camaro ZL1, while the supercharged 6.2L V8 LT5 can be found under the hood of the C7-generation Chevrolet Corvette ZR1.
With enormous output and tunability, these blown LT engines are a fantastic choice for an engine swap. However, making the accessories work as intended can be difficult. Luckily, the new Holley system corrects that.
The kit comes with an integrated hydraulic power steering pump, as well as a throttle body adapter to correct the aggressive angle of the OEM design, providing better positioning for engine swap applications.
The kit also keeps the original belt path for the supercharger drive, utilizing the factory tensioner. Holley designed the accessory layout specifically for swap applications, and the kit includes an LT4-style premium alternator, an LT4-style water pump design, an SD7 A/C compressor, A/C line adapters, a Type II power steering pump, and power steering hard line adapters.
Further features include a splined dual bearing system, which works to reduce belt stress on the power steering pump’s internal bearings, extending its life.
Hardware is included. Holley offers versions of this kit for both wet and dry sump applications, as well as either a black or natural finish.
Pricing for the LT engine mid-mount accessory kit listed on Holley’s website at $2,599.95, down from the original MSRP of $2,889.00

That is so complex and unnecessary! In my Ford Fusion Hybrid, all of the accessories are electric driven, so its 2.0 L I4 engine has no pulleys or belts. Soon we will have no engine at all with the new electric vehicles, such as the Ford Mustang Mach-E. Instead of a big lump of iron and all that mess of belts and pulleys under the hood, the Mach-E bay is empty, and has a waterproof box that can hold even ice and cold drinks!
How is the Alternator driven without belts?
It has no alternator. The HV battery uses a DC to DC converter to supply 12 volts.
Raymond, your on the wrong forum. Go talk about your Ford and how great it is on a Ford forum. Go hug a tree while your at it.
You are such an ignorant guy!
A belt system is much simpler if you have an ICE engine. With a belt, you are directly transferring mechanical rotational energy to your accessories. Electric driven accessories require the car to turn the rotational energy of the engine into electrical energy, and then turn that electrical energy back into rotational energy. A belt is simpler and more efficient in this case.
