Cars from the 70s aren’t known for having laser-sharp handling or the best ride, but those issues can be addressed with an upgraded chassis. Schwartz Performance has created a G-Machine chassis that will update the 1973-1977 GM A-Body platform. This new G-Machine Chassis is a bolt-in upgrade that will turn your A-Body into a vehicle that handles like a race car and rides like a luxury car.
The G-Machine Chassis is formed with a pair of heavy-duty mandrel bent rectangular steel main frame rails designed to roll right in place of the stock frame and lining up directly to the factory body mount locations. In fact, no major floor modifications are required, unless you plan to mini-tub the rear end of course.
The updated front suspension includes needle bearing supported A-arms for smooth bind-free movement along with separate caster and camber adjustments. Extra-long coilovers have been positioned at each corner to improve the handling while providing a modern, luxury ride quality. A power rack and splined sway bars with billet arms are also provided as standard equipment.
The rear suspension consists of a triangulated four-bar system with bind-free, Teflon-lined spherical rod-ends coupled to a full-floating Moser 9-inch rear end complete with your choice of gears and a Truetrac. The long list of standard equipment for the G-Machine Chassis includes adjustable RideTech Coilovers, a power rack and pinion, splined sway bars, and a big, bad Baer brake system (6P/SS4+).
The G-Machine Chassis is designed to welcome nearly any Chevrolet drivetrain and features an adjustable transmission mount. In fact, Schwartz can supply any drivetrain you’re looking for including an LT1 or LT4, 8-speed automatics, or even an old-school small or big block! We can also help choose and supply your specific tire and wheel combination.
