It’s hard to imagine that a suspension system that’s been utilized under thousands of trucks needs to be overhauled, but with over 25 years in the aftermarket designing, building, and repairing chassis, the Roadster Shop has seen their fair share of sheared brackets, bent control arms, and alignment problems. Replacing inadequate bushings and components on a regular basis and the restrictions and lack of a user-friendly design that went into many existing Mustang II-style setups sealed the deal when the guys at the Roadster Shop decided it was time to revamp the 30-plus-year-old design.
To do so, the crew started with a blank canvas, in this case a fresh CAD file using the SolidWorks program. From there, REVO IFS was born, complete with 115 unique components designed exclusively for the new frontend. Controlled roll centers, eliminated bumpsteer, and CAD-optimized camber and caster curves provide a suspension system that combines the best combination of handling and ride quality. A set of positive and negative bumpstops provides positive reinforcement should the entire 5½ inches of travel be utilized, allowing smooth articulation through the full range of motion.
Designing the new REVO IFS using 21st century CAD software also gave the crew the ability to carefully design a package that fit within the parameters dictated by most classic truck applications. The result is one of the smallest crossmember footprints, leaving more room and clearance for drivetrain positioning, and a new and innovative integrated sway bar design that uses a large, 1-inch splined tube with no external mounting necessary.
When asked why the Mustang II-style IFS system needed to be upgraded in the first place, Roadster Shop crewmember Chris Gray had this to say, “While the Mustang II was adequate 20-30 years ago, modern vehicle handling and comfort have moved on, leaving it far behind as a standard to ‘upgrade’ your truck to. Why ‘upgrade’ to a 40-year-old design and engineering philosophy? With completely overhauled geometry, modern construction and manufacturing methods, and over 115 unique REVO-specific components, we created a completely new setup. Each part of the entire assembly is either selected or built specifically for this system. No expense has been spared in the manufacturing, development, and fabrication of this system.”
While most of us aren’t building our trucks to be autocross competitors or canyon carvers, it is hard to argue with the safety, reliability, and performance of having a true, modern suspension system under that new build. You wouldn’t grow out a pair of mutton chops and slap on a powder blue corduroy three-piece suit to go out on a Friday night, so why would you use a suspension setup of similar vintage under your truck?
Roadster Shop currently offers the REVO IFS as a direct fit kit for ’48-56 Ford and ’47-59 Chevrolet pickups for those who want to drop it into their existing chassis. For a more modern approach, they also offer it as an option on their full chassis for ’48-56 Ford trucks and Chevys from ’47-66. A universal kit is also available for custom applications not covered by the current drop-in setups. Check out www.roadstershop.com for pricing and details.
