’55-’57 Chevy ExtReme IRS Chassis

$27,999.00

With our new ExtReme “Tri-5” full chassis, classic Chevy owners can get that cool, low stance on wide front tires without clearance issues or the extra expense, poor ride quality or leaks of air bags. The real ExtReme bonus is plush street manners AND insane handling capability! Sporting the same suspension design as our other ExtReme products, we’ve been able to outfit the ’55, ’56’, and ’57 Chevys with wider tires, lower stance, and incredible handling without sacrificing ground clearance or ride quality.

Coupled with the newest and most state of the art front suspension geometry design, unique only to the Speedtech Tri-5 chassis is the most bind free rear street suspension available, our road and track proven Torque Arm. This 3-link style suspension allows incredibly smooth transitional movement as the suspension articulates, translating to a smooth ride with amazing handling capability. And, it’s adjustable to cater to your specific needs and driving style! Check out the details of this complete chassis below!

Our new ExtReme full frame comes with a complete front and rear suspension incorporating the same parts used on all of our ExtReme full frames and subframes. On top of that it’s a totally customizable package, so whether you’re looking to build a strict street and show cruiser, a total track beast or you want a combination of both, we can put together a package catered specifically to your car and driving style!

Factory steering columns may not be the right length for the correct steering shaft angle and may not work with the ExtReme suspension components. We recommend an Ididit steering column for best results. Please speak to your sales rep to order a column from us or to obtain the correct part number.
