Thinking about a 68 camaro suspension upgrade is usually the first thing that crosses a gearhead's mind after they realize how poorly these classic F-bodies actually handle corners. Let's be honest: while a '68 Camaro looks fast standing still, the factory suspension tech from the late sixties feels more like a boat than a sports car. If you've ever taken a sharp turn and felt like the door handle was about to scrape the pavement, you know exactly what I'm talking about. The good news is that the aftermarket support for these cars is insane, and you can transform that wallowy ride into something that actually sticks to the asphalt.
Why the Stock Setup Struggles
Before you go throwing parts at the car, it helps to understand why the original setup feels so vague. Back in 1968, Chevy wasn't building these things to pull high lateral G-loads on a track; they were built for cruising and straight-line blasts. The front end uses a subframe design with stamped steel control arms, while the rear sits on leaf springs.
The biggest issue is the geometry. The stock upper control arms are designed with very little positive caster, which is why the steering feels light and twitchy at high speeds. Then there's the body roll. Those skinny little factory sway bars (if your car even has them) don't do much to keep the chassis flat. When you combine that with fifty-year-old rubber bushings that have likely turned into something resembling beef jerky, it's no wonder the car feels disconnected.
Starting with the Basics: Bushings and Shocks
If you're on a budget, the smartest way to start your 68 camaro suspension upgrade is by replacing the wear items. You'd be surprised how much better a car feels just by swapping out rotted rubber bushings for polyurethane ones. Poly bushings are stiffer, which means less deflection when you're pushing the car. The downside is they can sometimes squeak, but for most people, the trade-off in handling precision is well worth the occasional chirp.
Next up are the shocks. Most old Camaros are running on tired, oil-filled dampers that haven't done their job since the Nixon administration. Stepping up to a high-quality gas-charged shock or even an adjustable unit allows you to dial in how the car reacts to bumps. If you want a smooth highway ride, you can soften them up. If you're heading to a local autocross event, click them over to a firmer setting. It's one of those "seat of the pants" upgrades that you'll feel immediately.
Fixing the Geometry with Control Arms
To really make the car handle, you have to address the front-end geometry. This is where tubular upper and lower control arms come into play. Most aftermarket tubular arms are designed with built-in caster. This "corrects" the steering, giving you more stability at speed and a better "return-to-center" feel when you're coming out of a turn.
Tubular arms are also lighter and stronger than the factory stamped pieces. Plus, they usually come with better ball joints and bump stops. When you combine these with a set of lowering springs, you're not just improving the way the car looks by getting rid of that "nose-high" 4x4 stance; you're lowering the center of gravity, which is huge for stability.
Taming the Body Roll
If you hate that feeling of the car leaning over every time you change lanes, a bigger sway bar is your best friend. A thicker front sway bar will keep the front end much flatter. However, don't just go for the biggest one you can find. You want a balanced setup. If the front is too stiff and the rear has no bar, the car might understeer (where the front tires lose grip and the car pushes straight).
Adding a rear sway bar to a '68 Camaro is a bit of a debated topic. Some guys love them, others feel it makes the rear end too "tail-happy." If you're building a street car, a solid front bar and a moderate rear bar usually provide a nice, predictable feel that won't surprise you in the rain.
The Rear End: Leaf Springs or 4-Link?
For a long time, the only real 68 camaro suspension upgrade for the rear was a new set of multi-leaf springs. And honestly, for a lot of street builds, that's plenty. A good set of dropped leaf springs can improve the ride and the stance without breaking the bank. You can also add "traction bars" or "CalTracs" to help prevent wheel hop if you're putting a lot of power to the ground.
However, if you want modern performance, the 4-link conversion is the way to go. This involves cutting out the leaf springs and installing a system that uses four arms to locate the rear axle, usually paired with coilovers. This setup allows the rear tires to stay planted much better over uneven pavement and gives you total control over the ride height and stiffness. It's a bigger job and definitely more expensive, but the difference in how the car handles mid-corner bumps is night and day.
Don't Forget the Subframe Connectors
The '68 Camaro is a unibody car, meaning it doesn't have a full frame running from front to back. It has a front subframe bolted to the body, and the rest is just sheet metal. Because of this, the car can flex—a lot. If you have a high-horsepower engine, you might even see the body panels start to misalign over time from the chassis twisting.
Subframe connectors are steel rails that tie the front subframe to the rear frame rails. They basically turn the car into a full-frame vehicle. This is a non-negotiable part of any 68 camaro suspension upgrade if you care about performance. It makes the suspension do the work instead of the body twisting and absorbing the energy. The car will feel tighter, rattles will decrease, and the steering will feel more direct.
Steering Box Upgrades
While you're under there messing with the springs and arms, take a look at your steering box. The original "Saginaw" boxes are notorious for having a "dead spot" in the middle where you can move the wheel an inch in either direction without the car actually turning.
Swapping in a modern quick-ratio steering box is a game changer. It makes the car feel much more modern. Instead of sawing at the wheel like you're driving a bus, you get a tight, responsive feel that tells you exactly what the front tires are doing. It's one of those modifications that bridges the gap between a "classic car" and a "driver's car."
Putting it All Together
Upgrading a '68 Camaro isn't just about buying the most expensive parts; it's about balance. If you put racing coilovers on the front but leave the worn-out leaf springs in the back, the car is going to handle strangely.
Start with a plan. Are you building a weekend cruiser that just needs to feel a bit more planted? Go with shocks, bushings, and a sway bar. Are you looking to hunt down Porsches at the local track? Then it's time for the full tubular arm and 4-link treatment. Whatever path you choose, a 68 camaro suspension upgrade is one of the most rewarding projects you can do. There's nothing quite like the feeling of a classic muscle car that actually goes where you point it. It gives you the confidence to really drive the car rather than just aiming it down the road and hoping for the best.
