-Swapping a Modern Chassis Under a Vintage Ford

Swapping a Modern Chassis Under a Vintage Ford

In the past, taking on a chassis upgrade for your classic truck always seemed like a monumental task, only to be taken on when addressing a full build. It was something that Scott Roth, co-owner of The Auto Shoppe in South Burlington, Vermont, recently dealt with regarding a 1956 Ford F-100 they had completed for a client a couple of years ago. While it delivered everything a classic hauler should while motoring down the road on its slightly modified original spine, it left the owner wanting far more in the way of overall handling and stance. What if you could rewrite the book to bring your ride the ultimate in handling and performance by making a simple phone call? We're here to tell you firsthand that's exactly what happened after Roth reviewed his options for bringing the truck to the next level and contacted the Roadster Shop in Mundelein, Illinois, for one of their new REVO IFS complete chassis packages.

Well-known for injecting the ultimate performance handling into their chassis and related components, the Roadster Shop wanted to raise the bar and create a new standard for the future with all-new engineering. Starting with a fresh sheet of paper they moved forward utilizing the very latest in CAD development software and design processes. The results yielded the REVO IFS, which features controlled roll centers, eliminated bumpsteer, and CAD-optimized castor and camber curves to deliver razor-sharp handling through the entire range of steering and suspension motion for an extremely well-balanced feel. Couple this with a fully boxed frame fabricated from 10-gauge steel, exclusive X-Brace center section, CNC-located mounting points, large diameter parallel four-bar rear suspension, and 1-inch splined front and rear through-frame sway bars, and you have a recipe for success. The Roadster Shop allows you to custom order your chassis with a multitude of options, including your engine and trans combination and numerous brake and shock upgrades.

1956 Ford F 100 Front Drivers Side

In preparing the Effie for transformation, Roth and his team methodically worked from front to back to make sure the chassis separation from the cab and bed would go off without a hitch. Under the hood there was plenty to do starting with disconnecting the battery and fuel lines. The team then drained the cooling system, removed all related hoses as well as the radiator, shroud, and supports, disconnected the throttle linkage, and all electrical-related underhood items. Inside the cab, the column shifter and steering column were then disconnected. Roth then raised the truck and continued on by unbolting the running boards, bed, disconnecting the pedals, and clamping the fuel tank line. The truck was then lowered where the team removed the bed followed by properly bracing the cab and front end (while up in the air) before separating them from the chassis. Of special note is that endless hours can be saved by keeping the nose and cab together; it just requires extra attention be paid so there is no panel movement.

Once the new chassis was received, the Auto Shoppe team disassembled it and prepared the frame and components for a fresh coating of gloss black. One of the many benefits of the Roadster Shop is that they include extensive reassembly information in print as well as online regarding their chassis and suspension assemblies. Seeing that the F-100 was rather unique with regard to the 292ci Ford Y-block V-8 and manual trans, the team fabricated custom crossmembers and mounts to perform with the Roadster Shop chassis. As they worked to complete the rolling chassis you could feel the electricity in the air knowing the truck would soon be ready for the street. Once the cab and nose were lowered back onto the new chassis and secured in place, the bed followed, accompanied by getting the driveline and electrical systems completed. Once the truck rolled off the lift you could immediately see the difference in the overall stance and attitude where it had a much more dramatic feel. Driving it confirmed everything the shop hoped for with a newfound connection to the road where handling and responsiveness were brought to a whole new level confirming that chassis swaps aren't just for full builds anymore. Dig it!
