Holley Accessory Drive Component Mount Set

Holley Accessory Drive Component Mount Sets: Engineered for Clean, Swap-Friendly Builds

When it comes to mounting your alternator, power steering pump, A/C compressor, and water pump in a tidy, purposeful package, few names carry more weight than Holley. Their lineup of Accessory Drive Component Mount Sets represents some of the most thoughtfully engineered front-drive solutions available for popular engine platforms — from classic small and big block Chevys to GM's modern LS and LT families, Ford small blocks, the Mopar Gen III Hemi, and even Ford's 7.3L Godzilla V8.

The Bracketless Design Philosophy

What truly sets Holley apart in this category is their patented bracketless mounting approach. At the heart of the system is a "bracketless" design, where the accessories bolt directly to the water pump for a clean, integrated form. The result is a dramatically tidier engine bay — the design offers superb engine visibility to show off your horsepower, not your accessories. This isn't just an aesthetic win; eliminating stacked brackets reduces potential flex points and simplifies the entire accessory mounting structure.

Mid-Mount, High-Mount, and Low-Mount Options

Holley offers Mid-Mount, High-Mount, or Low-Mount Accessory Drive Systems for your engine, giving builders the flexibility to match clearance requirements in any chassis. The Mid-Mount drive completes Holley's trilogy of accessory solutions, giving a third option compared to the High and Low-Mount previously released. For racers pushing the limits, Holley has race mid-mount accessory drive systems available that eliminate air conditioning or air conditioning and power steering.

Truly Complete Kits

Holley's component mount sets go far beyond simple bracket hardware. The Mid-Mount system comes with everything you need — all accessories are included: the water pump, A/C compressor, alternator, and P/S pump with reservoir. All pulleys and the belt are supplied, along with A/C line adapters, heater hose adapters, power steering hardline, and the alternator plug/harness. Premium versions for GM LT4 and LT5 applications take it even further: Holley incorporates a splined dual bearing system that eliminates all belt stresses on the P/S pump's internal bearings, assuring long life.

Innovative Alternator and Compressor Technology

The included components reflect genuine engineering ambition. The premium alternator utilizes 6-phase technology as found on the C7 Corvette, while the water pump also shares its design efficiencies with that of the C7 Corvette, and the compact and reliable SD7 A/C compressor and Type II P/S pump with baffled reservoir are also integrated. For the Gen III Hemi, the innovative Holley premium alternator incorporates 6-phase and square wire technology.

Swap-Friendly Features and Finish Options

Among the many swap-friendly features are bottom heater outlets for clearance in tight applications, making these kits especially popular for LS and LT engine swaps into classic muscle cars and trucks. Easy assembly was a priority during the entire development of this accessory solution, and color graphical instructions walk you through every step of the ultra-easy installation. All types of different finishes are available — from Natural Aluminum, Black, or Polished Finish — so the drive system can complement any build aesthetic, from stealth sleeper to show-stopping showroom piece.

Whether you're swapping a Gen V LT into a first-gen Camaro, dropping a Gen III Hemi into a vintage Mopar, or refreshing a classic small block Ford, Holley's accessory drive component mount sets deliver a clean, reliable, and complete solution backed by decades of performance engineering expertise.
