The Best 1973 Mustang Front Suspension Kit Upgrades

If you've been living with the factory ride quality of your classic Pony car, picking up a new 1973 mustang front suspension kit is probably the single best favor you can do for your back and your steering wheel. Let's be honest—by 1973, the Mustang had grown into a pretty big car. It was the final year of that massive first-generation body style, and while it looks iconic, the stock handling often feels more like a luxury barge than a nimble corner-carver.

If you're still running the same springs and shocks that the car rolled off the assembly line with back in the Nixon era, you're not just dealing with old technology; you're dealing with fifty years of metal fatigue. It's no wonder the car wanders across the lane or dives like a submarine every time you hit the brakes.

Why Your Old Suspension Feels So Tired

The 1973 model year was a bit of a transition period for Ford. These cars were heavier and wider than the original '65 models, which meant the suspension had a lot more work to do. Most of these cars came with a basic independent front suspension setup using coil springs, upper and lower control arms, and a thicket of rubber bushings that have likely turned to dust or hockey pucks by now.

When you install a modern 1973 mustang front suspension kit, you're essentially deleting decades of "slop." You know that feeling where you turn the steering wheel two inches before the car actually decides to change direction? That's not just a steering box issue; it's often the result of worn-out ball joints and soft bushings that can't hold an alignment to save their lives.

Upgrading the front end doesn't just make the car safer; it makes it fun again. You stop dreading cloverleaf on-ramps and start looking for excuses to take the long, curvy way home.

What's Actually Inside a Front Suspension Kit?

Usually, when you start shopping for a 1973 mustang front suspension kit, you'll find a few different "levels" of hardware. If you're just looking to restore the factory feel, a basic refresh kit might just include the wear items. But if you want to actually improve the car, you're looking at a more comprehensive setup.

The Control Arms

Standard 1973 Mustangs used stamped steel control arms. They worked fine for grocery getting in the 70s, but they flex under heavy loads. Many high-end kits replace these with tubular control arms. These are lighter, much stronger, and usually designed with improved geometry that helps keep your tires flat on the pavement during a turn.

Bushings: Rubber vs. Polyurethane

This is where a lot of the "feel" comes from. Traditional rubber bushings are great for absorbing road noise, but they're squishy. Most performance kits move to polyurethane. It's stiffer, which means your alignment stays consistent, but it can occasionally squeak if you don't grease it well. It's a trade-off most enthusiasts are happy to make for the massive increase in steering response.

Springs and Shocks

This is the heart of the kit. You can stick with a traditional coil spring and a high-quality gas shock, or you can go the modern route with coilovers. Coilovers are great because they let you dial in the exact ride height you want. If you want that aggressive, nose-down "pro-touring" look, coilovers are the way to go.

The Massive Benefits of Modern Geometry

The coolest thing about a modern 1973 mustang front suspension kit isn't just that the parts are new; it's that they're designed better. Engineering has come a long way since the early 70s. Modern kits often build in more positive caster.

Back in the day, cars didn't have much caster because it made the steering heavy (and not everyone had power steering). But today, we want that "return to center" feel and high-speed stability that extra caster provides. When you swap in a modern kit, the car stops "hunting" at highway speeds. You can actually relax and enjoy the drive instead of white-knuckling the steering wheel at 70 mph.

Is This a DIY Project?

I get asked this a lot. If you have a decent set of jack stands, a stout floor jack, and a weekend with no plans, you can absolutely install a 1973 mustang front suspension kit yourself. However, you need to be careful. Coil springs are under a massive amount of tension. If you've never used a spring compressor before, take your time and watch a few videos first. You don't want a spring flying across the garage.

The real challenge usually isn't the new parts—it's getting the old ones off. Fifty years of road grime, heat cycles, and maybe some rust can make a simple bolt feel like it's been welded in place. A good torch and a big breaker bar will be your best friends here.

Once you get the old components out and the shiny new parts bolted in, the car will look like a million bucks. But don't go for a high-speed blast immediately. You'll need to get the car to an alignment shop right away. Even if you're careful, your toe-in and camber will be way off, and you'll ruin a pair of front tires in a matter of miles if you don't get it professionally aligned.

Choosing the Right Kit for Your Driving Style

Before you drop the money on a 1973 mustang front suspension kit, think about what you actually do with the car.

  • The Weekend Cruiser: If you just want to drive to local car shows and get some ice cream, you don't need a thousand-dollar racing setup. A basic kit with high-quality shocks and new rubber bushings will make the car feel brand new without making the ride too harsh.
  • The Daily Driver: If you're actually putting miles on the car, look for a kit that emphasizes "streetability." You want something that handles bumps well but doesn't feel like a pogo stick.
  • The Canyon Carver: If you want to keep up with modern sports cars, look for tubular arms, coilovers, and maybe even a thicker sway bar. This will flatten out the body roll and make the heavy '73 feel a lot smaller than it actually is.

The "While You're In There" Factor

One thing to keep in mind is that once you take the front end apart to install your 1973 mustang front suspension kit, you're going to see everything else that's wrong with the car. It's the classic "restoration creep."

You'll look at the brake lines and think, "I should probably replace those." You'll see the steering linkage and realize the tie-rod ends are shot. You might even decide it's time to upgrade to disc brakes if you're still running the old drums. It's better to budget for these things now rather than getting halfway through the job and realizing you need to wait another week for more parts to arrive in the mail.

Final Thoughts on the Upgrade

Investing in a 1973 mustang front suspension kit is easily one of the most rewarding things you can do for your classic Ford. It's not a flashy engine mod that makes a ton of noise, but it changes the entire personality of the car. You go from "navigating" the road to actually driving it.

The 1973 Mustang has a presence that few other cars can match. It's long, it's wide, and it's unapologetically American. Giving it the handling it deserves is like giving an old athlete a new pair of knees. It won't turn it into a 2024 GT350, but it will make it a car that you genuinely enjoy driving every single time you turn the key. So, grab some wrenches, clear out the garage, and get to work—your Mustang will thank you for it.
