Out at Dino's Git Down in Glendale showing off our fully loaded Level 3 airbag chassis built specifically for 1947-54 Chevy 3100 short bed trucks. Spencer breaks down everything from the Flaming River power steering to the LT4 motor mounts, Wilwood brakes, Currie rear axle, and Accuair E-Level Plus air management system.

This chassis lays frame on the running board brackets and comes ready for an LT4 with 10-speed transmission. Running 14-inch Wilwoods up front, upgraded 35-spline rear axle with 1350 U-joints to handle serious power, Falcon shocks, modular bolt-on design with grade 8 hardware, and powder coated in our signature FFG Grey with Casper clear coat for protection.

Everything's dialed in - stainless brake lines, braided fuel lines routed inside the frame rails for that super clean look underneath. Dual battery boxes, rear Watts link, all billet components. Built by Porterbuilt and fully loaded by FFG, this is the best foundation money can buy for a classic Chevy truck build.

This specific chassis is AVAILABLE FOR SALE right now. Buy it as a rolling chassis ready for your drivetrain ($39k without wheels/tires), or we can equip it with a complete LT4 long block with Whipple supercharger, headers, exhaust, and driveshaft. With the drivetrain package, we can have a full Designer Series painted truck done in about 6 months instead of the typical 9-12+ month timeline.
If you're serious about building a classic Chevy truck the right way, this is your shortcut. Reach out to us before this one's gone.
