One of the few beauties of being alive in 2024 is it's easier than ever to achieve the dream of a classic muscle car with modern performance. Aftermarket companies are slinging all manner of bolt-on EFI conversions, overdrive swaps, disc brake kits, and engine mounting solutions to help you bring vintage iron to the 21st century. 

Note that I said easier than ever. Things aren't as simple when we're talking about steering and suspension upgrades, where a new part like a steering box or control arms might yield some improvements, but true transformation is still held back by the dated engineering around it. Swapping to a different configuration altogether that will actually make it drive like a new car takes a lot more effort, fabrication skills, and money.

Heidts Hot Rod and Muscle Car Parts is among the few aftermarket companies that are working to change that tune, producing complete suspension conversions for old Fords, Chevys, and Mopars that make dramatic improvements over what rolled off the assembly line back in the day. The systems they offer are the likes of what you would usually work up with custom builders—except it's a bolt-in kit sent to your door under a single part number, and you install it yourself on your car. But can it really be that simple?

That's what I'm here to find out with my 1969 Dodge Charger project. Over the coming weeks, I'll be installing and testing Heidts' Pro-G bolt-in independent front suspension and bolt-in 4-link rear suspension kits on my pride and joy. This isn't gonna be your average product review. My goal is to take you through the full experience of installing them on my car from start to finish to give a deeper look at what this kind of intensive DIY upgrade entails, how realistic it is for the average owner to attempt—and how it actually changes the car's handling in the end.

Heidts Hot Rod and Muscle Car Parts has been around for over 30 years. Over the years, it's been honing its edge in producing kits that balance massive improvements while keeping things as simple as possible on the installer end of
