SEMA 2019: Chris Alston Shows Riviera With New Custom Fit Chassis

There are many sights and sounds at SEMA, the biggest automotive trade show on the planet. Of all the attractions at this big daddy of all automotive extravaganzas, the sight of a slammed, boat-tail Riviera at Chris Alston Chassiswork’s booth might have been one of our favorite rides brought to the Nevada desert. In bare metal and a block long, this Bill Mitchell masterpiece had blown Katech LT4 power and a sinister stance courtesy of Chassiswork’s new Custom Fit Chassis. 

We chatted with Chassisworks guru Lino Chestang and he filled Power Automedia in on all the details of their new, scalable chassis.

“The car we have here today is a 1972 Riviera that’s being put together by Gas Monkey Garage and they used our modular frame system on the car,” says Chestang. “Its outfitted with our rocker arm independent rear suspension and double A-arm front suspension, with billet aluminum unit bearing center-lock hubs on it. The frame system can be varied in track width and length, scaling up or down for a car as small as an Anglia or something as large as this old Riviera.”

Chestang continues, “We offer our independent rear suspension in four different track widths, 54 to 60 inches. We make the front cross member in 15 different widths as well. We have many different rear suspensions that you can specify. Two versions of the IRS: a triangulated four-link, and a torque-arm suspension. We also offer a parallel four-link rear with ladder bars, so if you’re going for a Pro-Street build, you can specify a narrow frame to accommodate bigger tires.  This system includes a complete floor system, with wheel tubs, trunk floor, a full floor in the front and a firewall and transmission tunnel.”

In other words, you can specify the length and width of the frame, and then choose suspension components, floor pans, and wheel tubs, and the end result is a darn near-custom frame minus the one-off cost and complexity.

Applications:

  • Pro-Touring Muscle Cars
  • Custom Trucks
  • Street Rods
  • Pro-Street and more…

Benefits:

  • Lower ride height
  • Fits much larger tires
  • More transmission room
  • Increased headroom; sit lower
  • 2 frame styles
  • 4 front suspensions
  • 6 rear suspensions

At the heart of this build is a Katech LT4 with a Magnuson Supercharger pushing close to 1,000 horsepower.
