If you're tired of your pony car feeling like a literal boat on the highway, it's probably time to look for a 68 mustang suspension kit that actually holds the road. Let's be honest for a second: as much as we love the 1968 Mustang, the factory suspension technology is over half a century old. Back then, "handling" meant you didn't flip over while making a turn at 30 miles per hour. Today, if you're trying to keep up with modern traffic or take a corner without your tires screaming in agony, you need an upgrade.
Upgrading your suspension isn't just about going fast; it's about confidence. It's about knowing that when you turn the wheel, the car is going to go where you point it instead of leaning like a sinking ship. But with so many options on the market, choosing the right kit can feel a bit overwhelming. Let's break down what you actually need to know before you start turning wrenches.
Why the Factory Setup Just Doesn't Cut It Anymore
The original suspension on a '68 was designed for bias-ply tires and much lower speed limits. It relied heavily on soft coil springs in the front and leaf springs in the back, paired with shocks that were basically just there for decoration. Over the decades, those parts have worn out. The rubber bushings have probably cracked and hardened into something resembling stone, and the springs have likely sagged, giving your car that "tired" look.
When you install a modern 68 mustang suspension kit, you're doing more than just replacing old parts. You're geometry-correcting the car. The original front-end geometry had a nasty habit of creating "bump steer"—that annoying sensation where the car darts in a random direction whenever you hit a pothole. Modern kits use revised control arm angles and better mounting points to kill that problem once and for all.
Deciding on Your Driving Style
Before you drop a couple of grand on a kit, you've got to ask yourself what you're actually doing with the car. Are you building a weekend cruiser, a daily driver, or a track monster?
The Street-Friendly Refresh
If you just want to enjoy a nice Sunday drive without feeling every pebble on the road, you don't need a full racing setup. A basic 68 mustang suspension kit that includes upgraded coil springs, heavy-duty leaf springs, and a decent set of gas shocks will work wonders. Throw in some polyurethane bushings to replace the old rubber ones, and you'll feel like you're driving a completely different car. It'll stay flat in the turns but won't rattle your teeth out.
The Pro-Touring Approach
Now, if you want that "modern car" feel—where the car handles like a late-model GT—you're looking at a more intensive kit. This usually involves moving away from the traditional coil-and-shock setup and going with coilovers. Coilovers give you the ability to adjust your ride height and stiffness on the fly. You can tuck the tires up into the fenders for that aggressive stance and then stiffen the dampers when you want to hit some twisty backroads.
What Should Be in Your 68 Mustang Suspension Kit?
Not all kits are created equal. Some are just "box of parts" assortments, while others are fully engineered systems. If you're shopping around, here are the components you should really be looking for to get the most bang for your buck.
Tubular Control Arms The stock stamped-steel arms are flimsy and prone to flexing under load. Tubular arms are way stronger and usually come with extra caster built-in. This makes the car much more stable at highway speeds and helps the steering wheel return to center naturally.
Thicker Sway Bars A big front sway bar is one of the cheapest ways to kill body roll. If your kit includes a rear sway bar too, even better. It helps balance the car so it doesn't understeer (where the front tires slide) as much.
High-Quality Shocks Don't skimp here. Shocks are the "brain" of your suspension. Whether they're adjustable or fixed-rate, you want something that's valved specifically for the weight of a classic Mustang.
Performance Bushings Old rubber bushings allow the suspension components to move around in ways they shouldn't. Polyurethane or even Delrin bushings keep everything tight and aligned, though keep in mind they can sometimes add a little more "road noise" to the cabin.
Don't Forget the Rear End
A lot of people focus so much on the front of the car that they forget the rear is still bouncing around on leaf springs. While you can certainly get a 68 mustang suspension kit that just gives you better leaf springs, there are cooler options out there.
If you've got the budget, a 4-link or a 3-link rear conversion is a game-changer. These systems replace the leaf springs entirely with links and coilovers. It gets rid of "wheel hop" (that violent shaking you get when you try to accelerate hard) and makes the back of the car feel much more planted. Plus, it gives you way more room for wider tires, which is always a plus on a Mustang.
The Reality of the Installation
I'm going to be honest with you: installing a full 68 mustang suspension kit isn't exactly a thirty-minute job. If you're doing it in your driveway, give yourself a full weekend, maybe two. You're going to run into 50-year-old bolts that are rusted solid. You're probably going to need a big breaker bar, a torch, and maybe a few choice swear words.
However, most of these kits are designed to be "bolt-in," meaning you won't necessarily need to be a master welder to get them on. The hardest part is usually removing the old, crusty factory parts. Once those are out of the way, the new stuff usually slides right into place. Just make sure you get a professional alignment as soon as you're done. You don't want to ruin a brand-new set of tires because your toe-in is all wonky after the install.
How It Changes the Driving Experience
Once you finally get that 68 mustang suspension kit installed and dialed in, the difference is night and day. The first thing you'll notice is the steering. It'll feel heavier in a good way—more precise and less like you're just suggesting a direction to the car.
When you hit the brakes, the nose won't dive toward the pavement anymore. When you take a sharp corner, you won't feel like you're about to slide out of your bucket seat. It transforms the Mustang from a car you "manage" into a car you actually drive. It makes those long road trips way less exhausting because you aren't constantly fighting the steering wheel to stay in your lane.
Wrapping It All Up
Buying a 68 mustang suspension kit is easily one of the best investments you can make for your car. Whether you're just replacing worn-out stock parts or going for a full-blown racing setup, the improvement in safety and fun is worth every penny. You get to keep that iconic 1968 styling that everyone loves, but you get the peace of mind knowing the car can actually handle modern roads.
So, take a look at your budget, decide how you want the car to sit and feel, and go for it. Your Mustang (and your lower back) will definitely thank you the next time you head out for a cruise.
