Holley Mid-Mount Accessory Drive System for LT Engines

Introducing Holley's Mid-Mount Accessory Drive System, specifically designed with the serious racer in mind! If you're looking for a front drive system for your LS engine racecar, we've got you covered. Choose from configurations without air conditioning and power steering to perfectly suit your needs.

This Premium Mid-Mount complete accessory system brings all the accessories in closer than traditional drives. At the core of this system is a unique "bracketless" design (Patent Pending), allowing accessories to bolt directly onto the water pump. This creates a sleek, integrated look, giving you fantastic engine visibility to showcase your horsepower instead of hiding it behind bulky accessories. Plus, for those tight setups, the system features bottom heater outlets for added clearance.

The innovative alternator designed by Holley is just as impressive. This premium alternator harnesses advanced 6-phase technology, similar to what's found in the C7 Corvette. The water pump also benefits from the efficient design inspired by the C7. You’ll find a compact and reliable Type II power steering pump with a baffled reservoir seamlessly integrated into the system.

The Mid-Mount drive completes Holley's lineup of accessory solutions, offering a third option alongside the previously released High and Low-Mount systems, all tailored for LS engines.

When we say "complete," we truly mean it! The Mid-Mount system comes with everything you need: the water pump, alternator, power steering pump with reservoir, and an SFI certified damper with a hard-anodized billet crank pulley. All pulleys and belts are included, along with heater hose adapters, power steering to -6 AN hardline, and the alternator plug/harness. We prioritized easy assembly throughout the development process, and the color graphical instructions guide you through each step of the installation.

The Premium Mid-Mount system also includes stylish pulley covers and an SFI certified damper, paired with a billet 6061-T6 aluminum hard-anodized crank pulley. Whether you're hitting the racetrack or just cruising around town, this system is ready for any adventure.
