Chris Alston's Chassisworks Gstreet Suspension - Chevy High Performance Magazine

Last month, we installed Chris Alston’s Chassisworks’ gStreet suspension on the front of Pat McNeil’s clean ’69 Chevelle. Now we’re moving on to the rear suspension; this should make sure all 765 horses stay hooked up on the street and on the track.

Similar to the gStreet’s front suspension, the g-Link rear suspension package is a complete bolt-on system, with the upper and lower control arms, your choice of VariShock coilovers or air springs, spherical rearend bushings, control arm braces, and an antiroll bar. All you need to do is choose between the air spring or coilover shocks, select a spring rate, and decide between single- or double-adjustable VariShocks.

Keeping the focus on straight-line performance, we went with the double-adjustable VariShock coilovers. When it came to the spring rate, Mike Saiki, from Motivational, went with the 200-lb/in VariSprings; this rate would offer the best weight transfer to the rear, all the while helping to keep the tires planted.

Getting 3,500 pounds moving is no easy feat so make sure you stayed tuned for round three, where we take the Chevelle through its paces and show you how well this suspension can perform at the dragstrip!

The first step was to install the spherical bushings in the rear housing for the upper control arms. Unlike a standard bushing, the spherical bushing allows the control arm to articulate with the movement of the rear suspension, preventing the suspension from binding.

The g-Link upper control arms feature Chassisworks’ maintenance-friendly pivot-ball assemblies with a zerk fitting and threaded retaining ring to keep the bearing inside the joint greased and moving freely.

Similar to the uppers, the lower arms also feature maintainable pivot-ball spherical joints. Any free play in the joint can be eliminated by tightening the retaining ring.

Since we’re prepping the Chevelle for quarter-mile duty, we went with specially valved double-adjustable VariShock’s with the low-friction COM-8 spherical-bearing lower shock eye. Our spring of choice featured a 12-inch length with a 200-lb/in rate width.

Using the bracket as a template, we then drilled out the other two holes (the ones closer to the front of the car) using a 5/16-inch drill bit and finished bolting it to the car.

To install the lower arm, we began by bolting it to the rear housing through the existing hole at the bottom of the shock. As we tightened the bolt, we made sure to use a level to determine whether or not the bracket was straight. Once the bracket was straight, we then drilled a 1/2-inch hole for the upper bolt, along with a 5/16-inch hole for the inner bolt.
