Your Chevy II Nova uni-body construction is inherently weak. Our G-Machine Chassis isn't.

The sheet-metal that your suspension components and engine are mounted to begins to flex dramatically once you add more horsepower, higher spring-rates and better brakes. With our G-Machine Chassis, your engine, rear-end, steering and suspension are isolated from the body. The G-Machine Chassis becomes the main support for your car and the uni-body structure simply becomes added support, helping to tie together the G-Machine Chassis.

The G-Machine Chassis is available for 1962, 1963, 1964, 1965, 1966 & 1967:

• Chevy II
• Nova

Installation is simple.

• You are not required to cut your floor-pan
• The only required cutting is of minor brackets
• The only required drilling is in the original rear frame rails
• Some welding required to your body in the rear

Want wider tires?

• Our 66-67 Chevy II G-Machine Chassis allow fitment of up to 335mm-wide rear tires if you minitub the wheel wells (**SOME CARS DO NOT FIT THIS! 315 WILL FIT FOR SURE)
  • 62-65 Chevy II's will fit at least a 295 with minitub, possibly wider depending on installation of minitubs. 
• The Moser full-floating 9" is narrowed to 54" hub-to-hub to allow a deeper dish on the rear wheels

Which options do I choose?

Brakes:

-Our 13" Wilwood kit is great for daily drivers and the occasional autocrosser or road racer. These require at least a 17" diameter wheel, though some 16" fit.
-Step up to the 14-inch Baer 6P Pro-Plus and get a brake system that will suit whatever you want to do. We race our 1965 Tempest often with this brake setup.
-The baddest kit is the Baer 6S, which is a one-piece forged caliper. This brake kit suits the hardcore roadracer, but does not sacrifice street driving.
-The 14" brakes require a 18" diameter wheel, however. Additionally, the Baer calipers are available in many colors, while Wilwoods are available only in black.

Coilover shocks:

We use RideTech coilovers as standard on our chassis systems. The two options we offer are single-adjustable and triple-adjustable. Single adjustable coilovers offer 24 "clicks" of adjustment for damping, as well as ride height adjustment. These will suit the weekend autocrosser/roadracer, as well as daily drivers. Triple adjustable coilovers offer the same damping adjustment as the singles with the addition of high and low speed compression adjustments, and a remote reservoir. These allow you to fine-tune your suspension for a specific type of driving. These are recommended for those who are willing & able to spend time tuning the shocks, and/or for the roadracer where every thousandth of a second counts.
Air ride is not available on our Chevy II chassis due to clearance.

Rear end housing:

Our standard axle is a Moser full-floating 9" style housing, with 31-spline axles. We have tested this rear end up to 1000hp street cars with no issues. Contact us for higher HP, or if you'll be drag racing it often on slicks with over 800hp. The Schwartz IRS option is for those craving an IRS in their musclecar. This is recommended for up to 700hp.

Third member/differential:

The Ford 9" comes with a clutch-type posi. Our first option is just that, with a cast-iron center section. If you have less than 500hp and won't be racing the car, this is just fine for you. The Detroit TrueTrac differential is a helical-gear type posi, which holds up to more power than the clutch posi, lasts longer (no wearable parts), and is quiet enough for street cars. Currie offers a new nodular iron case which is recommended for 600+ hp and racing. Their HD aluminum case also holds up to higher horsepower than the cast unit, and is much lighter than iron cases.
