Holley Accelerator Pedal Assembly

Holley Drive-By-Wire Accelerator Pedal Assemblies

When you're deep into an engine swap build, few components are as deceptively critical as the accelerator pedal assembly. Swap in a modern GM LS, LT, or Mopar Gen III Hemi engine and you quickly discover that your classic vehicle's old mechanical throttle cable setup is entirely incompatible with today's electronic throttle control systems. That's exactly the problem Holley engineered its Drive-By-Wire (DBW) accelerator pedal assemblies to solve.

Built Around the Engine Swap Community

Holley's reputation in the performance aftermarket traces back well over a century, but in the modern era, the brand has become synonymous with making ambitious engine swaps accessible. Accelerator pedal assemblies are a natural extension of that mission. Rather than forcing builders to fabricate custom pedal mounts or source hard-to-find OEM sensors, Holley developed purpose-built DBW pedal solutions that integrate seamlessly with their broader EFI ecosystem.

Plug-and-play compatibility with Holley EFI is the defining feature across the entire accelerator pedal lineup. Each assembly is designed to bolt directly into stock pedal locations when paired with the corresponding Holley DBW Pedal Brackets, eliminating guesswork and reducing installation time significantly.

Key Product Lines

Holley offers two primary accelerator pedal assemblies, each targeting a distinct platform:

• Holley 145-160 (GM LS/LT Applications): Designed for GM LS and LT engine swap builds, this steel, black powdercoated assembly mounts to the floor and is the go-to choice for a wide range of GM F-Body, Tri-Five, C10 truck, S10, and G-Body projects. It pairs with a family of vehicle-specific DBW pedal brackets spanning platforms from the 1955–57 Chevy Tri-Five all the way through 1988–2002 OBS GM trucks. It also works with Holley’s Terminator X Max and Dominator EFI ECUs for a fully integrated throttle control solution.
• Holley 145-312 (Mopar Gen III Hemi Applications): Purpose-built for Chrysler, Dodge, and Mopar Gen III Hemi engine swaps, this firewall-mount assembly is finished in black powdercoat and directly replaces Mopar OEM part #4861716AE. It fits 2007–2022 Dodge Charger, Dodge Challenger, Chrysler 300, and Dodge Magnum applications across a broad range of engine displacements from 2.7L through 6.4L.

Why Holley Gets It Right

What sets Holley’s accelerator pedal assemblies apart is the ecosystem approach. These aren’t standalone components thrown together for a quick sale — they are engineered to work within Holley’s complete DBW system, from the pedal sensor through the ECU to the electronic throttle body. The result is consistent throttle response, reliable signal communication, and a factory-quality feel in a custom-built vehicle.

The assemblies feature durable steel construction with a black powdercoat finish, giving them a clean, modern appearance that suits both show builds and daily-driven project cars. Whether you’re dropping an LS3 into a first-gen Camaro or transplanting a 6.4L Hemi into a classic Mopar muscle car, Holley’s DBW pedal assemblies ensure that the connection between your right foot and your engine is as precise and modern as the powerplant under the hood.
