This was a challenge to build but fun - we took one of our production chassis and made a custom front suspension to accommodate the Cummins Inc R2.8 crate turbo diesel then connected it to Gearstar Performance Transmissions built 4L80 transmission. It rolls on Detroit Steel Wheel Dtown smoothies with Back Classics redline tires - lots of custom work done on this one

We can’t wait to see how finishes the build of his patina 1950 Chevy Suburban

Going to bring our fabricated frame rails for the 48-55.1 Chevrolet or GMC trucks to the Advance Design Nationals - they will work with 1/2 ton, Suburban or Panel Trucks.

These are made to match the dimensions of the factory chassis with the 2 x 6 main frame rail, same front bumper horns but have a small notch for the slammed coil over chassis or the large notch for the air bag chassis (both require bed modifications)

The rails have tig welded 5/16-24 threaded bungs in the factory locations so you can reuse your original running board brackets and battery tray or purchase new from the aftermarket

This is a great headstart for you to fabricate your own custom chassis - don't waste time and energy boxing an original frame

We will have (1) pair of the air bag rails and (1) pair of the slammed coil over rails that you can take home from the show

1948-1955.1 Chevy or GMC truck frame rails $3300 pr.

The rails are made on our frame rail fixture and are the same rails we use for our custom chassis. They have 5/16-24 threaded bungs welded in for the running board brackets and battery tray - you can use your factory brackets or aftermarket

We have one of each style currently available:

Stock Style (7"-9" ride height - no modifications needed)
Slammed Coil Over (5" ride height - bed modifications needed)
Air Bag (4" ride height to laid out - bed modifications needed)
*Measurements are based on 28" tall tire - your ride height will vary on tire size

The rails will come straight so you can make the factory A-Frame style chassis, or you can cut and pinch the back for a custom chassis for a wider wheel / tire setup

They can be used for short bed trucks, suburbans or panel trucks

Message us if you're interested in a pair of rails or have any questions on our chassis or parts

Air Bag (4" ride height to laid out - bed modifications needed)
