Now your classic 1955-1957 Chevy can have the handling characteristics of an exotic sports car! All it takes is a CAD engineered replacement chassis from Art Morrison Enterprises Inc., and it's a project that most competent do-it yourselfers can accomplish in their own home garage. Little or no welding is required to install this chassis.
Up front, we've designed a suspension that provides an excellent combination of ride comfort, cornering agility and high speed stability. Tubular steel control arms and Strange Engineering adjustable coil-over shocks are employed, while a matched rate 1" diameter sway-bar controls body roll.
In place of the antiquated OEM steering box we offer the superb power rack & pinion from DSE. The 20:1 ratio is ideally suited for most highway driving. Other options available.
The chassis has been engineered to accommodate all popular transmissions, including Powerglide, TH350, TH400, and 700-R4 automatics, as well as any 4-speed, Tremec TKO and T-56 6-speed, Richmond 5-speed or 6-speed manual transmissions.

Give Any 55-57 Chevy "Sports Car Handling" With A MorRison Tri5 Chassis!
Imagine having a car that has the classic looks of a Tri-5 Chevy combined with the ability to handle curves like a slot car, stop on a dime, and accelerate like a rocket. It's easy when an Art Morrison "GT Sport" chassis is part of the equation. We made it happen by putting the chassis underneath an otherwise-stock 1955 Chevy. Comprehensive skid pad, slalom, acceleration and braking tests confirm that Morrison's GT55 performs like a sports car.

The Art Morrison 1955 Chevrolet the "GT55". We made it happen by putting the chassis underneath an otherwise-stock 1955 Chevy, dropping in a 427 c.i.d. small block Chevy Hardcore crate motor from Bill Mitchell (dyno rated at 530 HP), and running the power through a Keisler Automotive T-56 6-speed. The car was driven from the Morrison shop near Tacoma, Washington down to California. Click on this link above to go directly to the photo album.
