1955-1959 Chevy Truck Pro-Touring Chassis

TCI Engineering 1955 to 1959 Chevy truck Pro-Touring Chassis. We began with our tried & true 8” tall main frame rails that follow the original frame profile.

We have taken what we learned from a decade of auto-crossing & road racing and integrated that technology into a new Pro-Touring IFS. We are using our custom-designed spindles with bolt-on steering arms. This allows us to maximize the performance aspects of suspension geometry. Including, camber gain, bump steer, ackerman angle, scrub radius, kingpin inclination, instant center, motion ratio, and more. This new Pro-Touring IFS still utilizes over-the-counter brakes, ball joints, and rack & pinion so replacements are readily available. Ridetech Million Mile Warranty coilovers are standard equipment. This new Pro-Touring IFS will provide the ultimate in handling, weight savings, strength, ground clearance, along with a broad range of alignment adjustments.

The Torque Arm rear suspension was designed to eliminate the bind that occurs when cornering using the stock conventional leaf spring suspension. For the Torque Arm to function properly the rear frame rails need to be stepped; this allows for proper Torque Arm and link bar geometry. This has the added benefit of lowering the center of gravity and moving some weight to the back of the truck making it more balanced. The Torque Arm features a telescoping slider at the front of the arm that rotates as the vehicle goes through suspension travel and articulation. This allows the handling to be controlled by the coil-over shocks and the rear sway bar with no suspension binding variables. Coilover location maximizes roll stiffness and helps keep the truck flat and planted. The kit also allows for a lowered stance and greater rear axle control dramatically improving the handling. There are 3 adjustments on the axle brackets giving you the capacity to change the ride height in one-inch increments. You also have the ability to fine-tune the ride height further with the Ridetech Million Mile Warranty adjustable coil-overs.

We offer a wide variety of additional options that allow you to custom tailor a chassis to meet your specific needs for your ’55-59 Chevy pickup truck Pro-Touring Chassis. All TCI Engineering products come with our Dual Warranty. 6 Year, 60,000 Mile Warranty on wear and tear. Any items built in-house by TCI Engineering come with a Lifetime Warranty.

Platform-level fitment (Ford + GM, Phase 1). We publish the engine platform a part is built for — not year-and-trim application data — so nothing here confirms a fit on a specific vehicle. Confirm fitment with us before ordering: (714) 202-7886.
