GT500 Accessory Drive Kit

The Accessory Drive Your GT500 Swap Needs

Dropping a GT500 into a classic truck is one of the boldest moves in the classic truck world. The power is there. The vision is there. But the factory GT500 accessory layout wasn't built for your truck's engine bay — and forcing it to fit means compromising the build you've worked too hard on.

This kit solves that problem completely. Clean install. Purpose-built engineering. Nothing left to figure out on your own.

Built In Our Shop. Proven On Our Builds.

We built it because we needed it. When we started putting GT500 engines into classic trucks in our own shop, the accessory drive problem was right there in front of us, and no clean solution existed, so we engineered one ourselves.

Every bracket position, every spacer dimension, every routing decision came from real time spent inside these builds. We ran it, tested it, and refined it until it worked exactly the way it should. What you're getting isn't a theory. It's the solution we rely on in our own shop, packaged and ready for yours.

This isn't a modified off-the-shelf kit. There is no other accessory drive solution built specifically for the GT500 F-100 swap. If you're building at this level, this is the kit that belongs under the hood.
