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
