About AGP

When you're serious about power.

AGP Speed & Custom is a custom auto performance shop specializing in domestic vehicles. Tuning, fabrication, restoration and performance consultation happen under one roof, and our mechanics treat every job like their own project.

The shop grew out of a simple idea: the people who plan a build should be the same people who weld it, wire it, paint it and drive it out the door. That keeps quality consistent and keeps timelines honest.

Whether it is a weekend cruiser, a track car or a daily that needs to stop and handle better, we scope the job, stage it to your budget and keep you posted as it moves.

Domestic performance specialists

GM, Chrysler and Ford are what we live in every day — swaps, boost and calibration included.

Everything under one roof

Fabrication, installation and tuning in the same shop, so a build never waits on someone else.

Treated like our own

Our mechanics are car people first. Every job gets the same care we'd give our own project.
