For some people, their classic car should be completely stock and look like it just left the factory. But many others want to full customize their classic for added style or driving dynamics. For those wanting to make some dramatic changes, keeping the stock chassis has its limitations. That’s where Illinois-based Roadster Shop has carved its space in the market, with modern chassis for American classic muscle cars, trucks and SUVs. The latest Roadster Shop chassis offerings are for the first and second generation Chevrolet K5 Blazer. RS already sells an off-road chassis for the classic SUV in various forms, but these new offerings allow for a chassis solution for Blazers as old as 1967, and as recent as 1991 model years that want to focus purely on a street aesthetic.
There are two new K5 Blazer chassis announced, and each are part of Roadster Shop’s Slammed SPEC series. One chassis is good for the 1967-1972 K5 Chevrolet Blazer, and the second one covers model years spanning 1973-1991 Blazer. Ride height is said to be as low as 4.5-5 inches.
Each chassis uses the company’s proprietary “laser rails” that allow for a complete assembly install. Along with CNC located factory mounts, installation with the factory body is mostly bolt on. Given Roadster Shop specifically designed these for slammed K5 Blazer SUVs, it will require some modifications to the inner fenders, trans tunnel, and bed floor to accommodate for the drop in ride height.
The chassis also have some customizability, letting owners truly make their Blazer exactly how they want it. The kit comes with either air bags or RS SV by Fox fixed valve coilovers. The air suspension will obviously allow for the biggest drop in ride height when aired out, letting the rockers laying on the ground when 29 inch tires are fitted. Either suspension option settles at a 4 inch ride height while driving, and the chassis and suspension geometry is designer for that height.
As for powertrain compatibility, the crossmembers and chassis bracing allow for 3 inch exhaust, and the standard engine mounts are designed for small block or big block Chevrolet motors. LS and LT engine mounts are optional.
While $10,795 is no small price, these K5 Blazer chassis will make it easier for owners to modify their vehicles, and they won’t have to worry about failure points of a 30 to 50 year old frame.
