Restoring a truck that has been in existence since the late ’40s or early ’50s is no easy task. Aside from all the normal wear and tear of having been used that long, there’s also the abuse and neglect it’s been through, which can sometimes only be fully apparent after it’s been disassembled. While you may have your work cut out for you with fixing up the body, interior, or engine, one the most daunting tasks for even the most skilled mechanic to deal with is assessing and making any repairs to the truck’s foundation.

Rotted-out bushings, bad shocks, bent metal caused by wrecks and hidden from plain view, and of course rust may just be some of the problems you encounter with a stock frame. Then you may possibly have to reinforce or retrofit portions so you can add more contemporary parts. That may put additional stress on factory metal that is old, brittle, and not originally designed for such upgrades. In other words, attempting to make those changes to a frame that’s 60 to 70 years old may just not be realistic. To be done correctly, it will take countless amounts of labor, time, and money and after figuring the total cost involved, it’ll leave you wondering if the juice is worth the squeeze.

Well that’s a question you have to ask yourself and in all honesty — and in an almost comical way — restoring an older frame is much like an older woman getting plastic surgery. It’ll work, but it just won’t be the same … and you might be worse off than when you started.

But all joking aside, the cost of repairing rust, boxing a frame, replacing worn bushings, and going the full nine yards will add up quickly, which is why the better choice would be going with a fresh frame from the folks over at TCI. These frames are custom crafted in the good ol’ USA and feature main rails with an extended height from 6 to 8 inches for increased rigidity and clearance between upper and lower X-members. They also retain their original profile and their re-engineered upper coil-spring towers accommodate a traditional shim-style alignment adjustment instead of T-bolts.

In addition, Total Cost Involved uses a vertical plate to mount the upper control arm, thus increasing camber gain and anti-dive for better performance. Further enhancements also include a Parabolic leaf spring kit, which has been moved closer to the framerail and makes room for wider wheel and tire packages. Of course, all TCI frames can also be customized to suit your exact needs, so if you’re willing to spend a little more money you can have a bespoke frame designed just for your own unique application.

With all these technological advancements, these frames provide a solid foundation for a good build, but along with that, they were designed to improve ride quality and increase performance. The TCI frames are also more suitable for drivetrain changes and other aftermarket components. Let’s face it, many of us want that vintage feel with more contemporary drivability than what stock frames will allow and they may have to be reinforced to deal with additional stress. Those who’ve tried putting an LS motor in a stock frame where a six-cylinder used to reside will know what we mean.

So how easy is it to slap all the necessary components onto a lowrider-style TCI truck frame? Well this DIY was put together to show you just that. Starting off with a bare TCI frame, it took us four hours to bolt up the tubular control arms, air suspension, Wilwood brakes, and a Currie rearend. Now keep in mind that the frame has no finish, but it’s proof once again about how easy it is to work with because by the time this article goes to print we would have already broken it all back down to get the frame and components chromed, polished, or powdercoated for the right finish.

Be sure to follow this special ground-up build. This is phase one of our Project Fifty Three resto-mod, which will soon have a new LS-X crate engine dropped in.
