Roadster Shop Launches Legend Series Chassis For K5 Chevy Blazer And C/K Trucks

Old-school rigs like the K5 Chevy Blazer and the C/K line of trucks are great, no doubt about it. However, with the right components underneath, these machines get even better. Now, Roadster Shop is aiming to offer exactly that with its new Legend Series chassis.

For those who may not know, Roadster Shop has established itself as the go-to solution for those builders that want to modernize a classic car, truck, or off-roader, offering a wealth of products spanning all the most-popular custom builds and restomods. Now, Roadster Shop has unveiled its new Legend Series chassis built specifically for the 1969 through 1980 Chevy Blazer and C/K trucks.

The Legend Series chassis is designed to provide modern comfort and drivability, plus modern durability and serviceability, all while maintaining the classic appearance of the K5 Chevy Blazer or C/K truck up top. The chassis is perfect for those builds that require easy installation without any of the guesswork, and is sure to delight once it hits the road.

Standout features include bolt-on chassis installation with no required body modifications, as well as Roadster Shop’s exclusive laser rail frame with integral crossmembers. The suspension spec incorporates a Chevy 1500 four-by-four independent front suspension with Fox coilovers and Roadster Shop’s proprietary valving, as well as Deaver’s progressive multi-leaf rear suspension with Fox shocks.

Braking is accomplished via factory Chevy 1500 front and rear discs, while CNC bent stainless lines make brake installation a breeze. Further details include an OEM Chevy 9.5-inch ring gear axle assembly, factory hydraulic power rack-and-pinion steering, and electronic push-button four-wheel-drive available on the fly. The chassis was also designed to fit the LT1 and LT4 V8 engines, and GM 8L90 eight-speed automatic transmission.

Of course, builders who want something a bit more custom have plenty of options to choose from, if so desired. Check out the video below to see the new Legend Series chassis in action:

  1. As a collision reconstructionist, it scares me that there are still people who ride the highways without wearing seatbelts, apparently oblivious to the risk they’re taking.

    Anyhow, the chassis looks really good, and I hope the idea will spawn more variations to keep more classic vehicles running better.

    Only thing is, it would have been great if they could have engineered something to improve those rear shock hangers.

    1. I’m an avid believer in seatbelts, and one day I hope to upgrade my C10 with seats from a 2000 or newer Chevy single cab with the integrated (lap and shoulder) seatbelts. Due to the location of the fuel tank, the floor isn’t flat, so it’s not a simple upgrade. It would be highly unsafe to relocate the fuel tank to the rear as is required, this truck did not come with a rear bumper. For those reasons, it’s going to be a massive undertaking on this truck. As I said, one day.

      The most annoying part is getting pulled over by cops in their 20s (even giving me tickets!), even though my partner and I are always wearing our lap belts, which are all that’s required (and available in this truck) for a 1974 light truck.

      Yes, I prefer modern seatbelts, but it’s my/our risk to take. The lap belt is better than nothing (and IS legally compliant), although risk of injury is significantly higher. Part of the story when driving an old vehicle, I know this truck has little in the way of safety features. Seatbelts alone won’t begin to make it comparable with a modern truck, but it’s one upgrade I fully intend on.

    2. The custom chassis industry has been doing very well for years with the last 10 or so extremely well as well as competitive. We’re putting an Art Morrison under my 58 wagon.

  2. I’m sure it’s a fantastic upgrade, especially over worn ~50 year old parts.

    I have a ’74 Custom 10 pickup (2wd) with manual steering, brakes and transmission. It has factory disk in the front and it stops very well. It also has the original 250 (4.1L) I-6, which was my main reason for buying the truck (I wanted an American truck with an old school Inline 6).

    It has less than 55k miles as of now, most everything I’ve replaced has been due to age and not use. I’m keeping the truck stock with minor upgrades (especially when replacement is necessary) like poly cab mounts, HD AC Delco shocks, and a nod to appearances with 15×7 rally wheels with GoodYear all terrains. The 6 cylinder required upgrades after the original emissions equipment failed and caused damage to the intake and exhaust manifolds. It is still the original engine, the most we took off was the side inspection plates and valve cover. We replaced the intake and exhaust with Clifford 6=8 and a Weber 2bbl, and Hedman hedders. The 6 starts on a dime and gets great mileage, while being well capable of 70-75 sustained travel on the highway (and it has more to give there, I’m just saying it isn’t stressed keeping up with modern traffic).

    I would love to find a ’73-74 GMC K10 and really build it with an upgrade like this. (That is, a worn out truck that needs upgrade, not a nice original well-preserved truck.) I love my 6 cylinder C10 but I like off-roading too, so an alternative would be nice. Maybe fully loaded since my Chevy is so basic (it doesn’t even have drip rails, which were optional in ’73-74 before Custom Deluxe trim became standard in 1975).

    Sorry for the long post, haha just proud of my old square body and thought some would appreciate hearing about it. I’ve owned it for a couple years, had something like 30k when I bought it and it would barely do 60 MPH with the intake/exhaust issues. It’s come a very long way. I’d love to post pics if I could.

  3. Does this new frame still have the side saddle gas tanks?

  4. Strange that they would list the application for 69-80. What’s different about ’67-68 and ’81-87 model years?

    1. I bet they will do them all eventually.

  5. What a home run ! Now if somebody would just make a reproduction cab……the demand for those has to be huge !
