Holley Engine Support Bracket

Holley Engine Support Brackets: Swap-Ready Precision for Every Build

When it comes to mounting accessories cleanly and securely on a performance or swapped engine, few names carry the credibility of Holley. Known for decades as a cornerstone of the performance aftermarket, Holley brings that same engineering discipline to its line of engine support brackets — offering builders a purpose-built solution whether they're completing a first engine swap or tightening up a dedicated race build.

Engineered for the Demands of Engine Swaps

Holley offers simple, clean, cost-effective solutions that solve the accessory drive challenges encountered when swapping a GM LS engine into a muscle car, truck, hot rod, or other vehicle. But the scope of Holley's bracket program extends well beyond LS platforms. If you're installing a late-model powerplant into a classic project, Holley has solutions to mount accessories to the front of LS, LT, Small Block Chevy, Big Block Chevy, Small Block Ford, Mod Motor, Coyote Motor, or Gen III Hemi engines.

These brackets were designed to deliver a factory-style appearance, correct belt alignment, and factory stability. That attention to OEM-level quality is what separates Holley's engine support brackets from generic alternatives — they don't just bolt on; they look like they belong there.

Universal Fit, Multiple Mount Configurations

One of Holley's key engineering achievements in this category is broad compatibility without sacrificing precision. Universal brackets fit virtually all common LS engines regardless of water pump and harmonic balancer offsets, reducing cost and complexity compared to competitive products, while simple dedicated installation kits allow easy fitment to Corvette, F-Body, or Truck drive offsets.

Builders can choose from Mid-Mount, High-Mount, or Low-Mount accessory drive systems, with finishes available in Natural Aluminum, Black, or Polished. This flexibility makes Holley engine support brackets suitable for everything from a weekend hot rod to a track-day build where appearance and weight matter equally.

Construction Quality Built to Last

Holley brackets feature factory-quality natural-finish die castings for clean looks and durability, and they utilize commonly available and affordable GM alternators and power steering pumps. The castings can also be polished, coated, painted, or plated — giving builders the freedom to match their bracket finish to the rest of the engine bay.

Holley's Mid-Mount accessory drives represent a revolutionary system that eliminates unsightly brackets entirely, thanks to an innovative water pump design with integrated mounts. For race applications, Holley also offers race mid-mount accessory drive systems available that eliminate air conditioning or both air conditioning and power steering for maximum weight reduction and underhood clearance.

A Trusted Name Behind Every Bracket

Holley's kits supply the required brackets and hardware needed for installation but allow you to choose the source for supplemental accessories and components — whether from the salvage yard, the local auto parts store, your GM parts dealer, or Holley's own premium matched components. That open-system approach means Holley engine support brackets work within virtually any build budget without locking you into a proprietary ecosystem.
