Description

Holley's complete accessory systems for LT4 and LT5 applications are designed to position all accessories high and tight against the engine. A key feature is the integration of a hydraulic power steering solution, which addresses a common need in engine swap projects. The system employs a splined dual-bearing design that isolates the power steering pump's internal bearings from belt stresses, promoting longevity. The supercharger drive maintains the original, optimized belt path and tensioner. The overall accessory layout is engineered to resemble an original equipment manufacturer (OEM) design, specifically for engine swap applications. The kit includes a throttle body angle-correcting adapter to optimize throttle body positioning for easier intake tube routing in swap configurations. Both wet and dry sump applications of the LT4 and LT5 engines are supported.
