Adrenaline Fabrication –

Custom Chassis with Built-In Flexibility

While Finish Line Speed Shop has years of experience in the custom chassis world, we’re proud to introduce a bold new division: Adrenaline Fabrication. Born from our passion for precision engineering and next-level performance, Adrenaline Fabrication has evolved into its own specialized entity—designed to meet the demands of today’s custom builders.

At Adrenaline Fabrication, we build multiple chassis variations tailored to your style, goals, and ride height preferences. Each chassis is crafted with a modular design, giving you the freedom to upgrade, modify, or expand as your vision evolves.

Because let’s be honest—sometimes we change our minds. And your chassis should be able to keep up.

Choose Your Style

Adrenaline Fabrication offers three distinct chassis series:

Adrenaline Series – Engineered for aggressive stance and all-around performance
Bagged Series – Built for full air-ride setups and maximum drop
Cruiser Series – Perfect for a smooth, functional ride with classic road manners

What makes our system special? Every chassis can be reconfigured between these three styles. Whether you're starting simple or going all out, your Adrenaline Fabrication chassis can evolve with your build—no cutting corners or starting over.
