Roadster Shop’s new LowPro platform for the 88-98 Chevy OBS Trucks is the industry’s first slammed chassis that does not require raising your bed floor. You can now build your OBS truck, which, when aired out, will sit virtually on the ground and retain the stock bed floor height for full use of the bed for hauling, storage or even your favorite cooler. 

This is all possible because of the low-profile trailing arm IRS system, utilizing an OEM GM differential with a completely new and innovative multi-link system supporting a trailing arm with airbag & cantilever shock set up.

ACME Chassis Factory is proud of their line of GM C-10 chassis which are currently available for all year C10 pick-up, Blazer, and Suburban in your choice of setup for air bags or coilovers. All of their chassis are completely 3D modeled on a state-of-the-art computer modeling program. From there, front and rear rails are constructed from laser cut and cnc formed 3/16 cold rolled steel. The lower control arms are designed and built with laser cut plate with internal gussets, for maximum strength. The tubular upper arms are fully adjustable for camber and caster alignment. The rear suspension features a triangulated 3-link with fully boxed lower links and a tubular upper link or a parallel 4-link with a Watt’s link. All machined parts are CNC-machined to exacting standards and tolerances. The chassis and components are all assembled and fully welded in precision jigs and fixtures to ensure a perfect fit. 

When building your dream C-10, it is crucial that you start with a good foundation. Unfortunately, these trucks we love were designed and built close to 60 years ago. When adding high horsepower motors, huge wheels, and giant brakes, an out-of-date weak frame just isn’t going to cut it. No matter how you brace or add cross members to it, you still have an old and weak frame. With our chassis, not only do you get a state-of-the-art suspension and steering system, but you get the strength and reliability of a properly engineered frame to build your dream truck on.

If you want your Squarebody to sit lower, handle better, ride smoother, and hug corners, the flimsy factory chassis just isn’t going to do it. There’s no secret that these trucks can only be lowered a little bit before the lower control arms are scraping the ground, the ride is harsh, and the alignment specs are out of whack. The cure is a completely new TCI chassis with exceptional strength and redesigned geometry for today’s performance standards. 

TCI offers their Squarebody chassis in three different configurations; Classic, Pro-Touring, and Grounded. No matter which one you choose though, there are some similarities. Their Squarebody C10 chassis starts with precision laser cut fully-boxed frame rails that are fully jig welded in their Ontario, California manufacturing facility. There’s a 12 piece center section that ties both frame rails together for a rigid platform to hold the suspension.

These frame rails get built at different heights depending on if you’re going for that Classic look with minimal drop, Pro-Touring with 4” ride height, or Grounded which slams the truck on the ground. The Pro-Touring chassis and the Grounded will have a step notch in the rear to get the truck low and have room for the suspension to do its job. The Classic series and Grounded series will have a four-link rear, while the Pro-Touring chassis has a Torque-Arm set up in the rear. 

In the front, they utilize their high-performance, track-winning Pro Touring IFS system. This package is designed to be compact and strong, providing you the precision steering and the confidence you deserve to push your truck further than ever without compromising comfort. Utilizing tubular control arms, the Pro Touring IFS features high-performance 1,000,001 warranty Ridetech fully-adjustable coil overs, rack and pinion steering, and Custom Modular spindles to choose a set of brakes to match the performance of the chassis. 

Need more proof this is the best chassis you can put under your truck? They offer a six-year 60,000 mile warranty on wear and tear items such as bushings, coil overs and ball joints. Any hard parts such as the frame, link bars, control arms, spindles, and cross members come with a lifetime warranty. 

Classic Series

  • Traditional 5”-7” drop
  • Pro-Touring IFS
  • Four-link rear suspension
  • No modifications to the bed floor

Grounded Series

  • Frame touches the ground (with 29” tall tires)
