Over 2.5 million of the legendary pony cars were produced, and even today there are still many on the road.

You’ll see that it’s easier and more affordable than you think to make some serious improvements to your pony car. Let us break down each of the major categories we mentioned.


The beating heart of your Mustang is its engine. Of course, your car needs a chassis, a body, wheels and a transmission. But it’s your engine that determines the true performance potential of your car — many of the top Fox Body mods are related to your engine. The most popular ones are:

• Cylinder heads: With upgraded cylinder heads, your Mustang can see a huge gain in horsepower. We carry many different models and designs, but they all have one thing in common: They enable your engine to create more power.
• Camshaft: Your cam is responsible for opening and closing your valves. Upgrading yours can go a long way to helping your engine reach its potential. While you’re at it, consider replacing your valve train and rocker arms with performance versions.
• Intake manifold: When it comes to freeing up extra power in your engine, swapping out your stock intake manifold for an upgraded version is a very popular Fox Body mod. Combine this with a cold-air intake and the difference is night and day.

Fox suspension Suspension upgrades are another essential part of the pony car performance equation. What good is all that extra power if your Mustang can’t handle it in the corners? With suspension mods from CJ Pony Parts, you can lower your pony car and give it flat, steady, confidence-inspiring handling at the limits. Consider your:

• Shocks and struts: The main component of your suspension, upgraded shocks and struts can lower the ride height of your car and eliminate sag and roll in corners and under hard braking
• Sway bars: The addition of a sway bar makes a world of difference in how your car feels when changing direction, providing a more planted feel during quick maneuvers.
• Sub frame connectors: No suspension modifications alone can correct the major flaw of the Fox Body: the weakness of its uni-body design. Sub frame connectors link the front and rear sub frames, allowing you to really dial in the handling performance upgrades.

Some of the other top Fox Body Mustang upgrades and bolt-ons that can make a significant difference to your performance are racing wheels and tires, aggressive brakes and improved rear axle gears. Combine all of CJ Pony Parts’ different performance-related parts to build a true thoroughbred for the road and track!


For hard-core Mustang racing fans, the name of the game is outright performance. You want everything to feel right and add to your enjoyment. With thousands of parts for your Fox Body in our catalog, you can be sure that we have tons of options to improve your ride. Make your Mustang the kind of car you want to spend hours in by updating the:

• Sound system: For many car fans, a road trip isn’t a road trip without the right soundtrack. A high-quality radio and speakers are easy to install and help the miles disappear.
• Shifter and steering wheel: Nothing beats the feel of a meaty steering wheel paired with a thick, short-throw shifter for complete control over your ’Stang.
• Seats: Even if the original Fox Body seats were relatively comfortable, years of use make even the best seats uncomfortable and unsupportive. Install some new seats and enjoy taking the long road home.

When you kick up the comfort factor of your Fox Body, you’ll be tempted to fire it up more often. You’ll want to head out for a spin just to experience the pleasure of the drive. Many of our customers also choose the following upgrades and modifications:

• Air conditioning: Upgrading your A/C to run a modern refrigerant ensures your Mustang is enjoyable even on the hottest summer day. If you’re swapping in a newer engine, such as the 5.0L Coyote, you may even be able to add A/C to a Fox Body that doesn’t have it.
• Air suspension: An adjustable air suspension combines the best of both worlds: maximum handling performance and the ultimate in ride comfort. Controlled from the driver’s seat, an air suspension lets you dial in the perfect settings for your driving mood.
• Exhaust: What would a Mustang be without a throaty exhaust sound? Our huge range of Fox Body exhaust components — from the headers to the exhaust tips and everything in between — means you can get the exact exhaust note you want.

Our bolt-on Fox Body parts and accessories can be installed quickly. They’re designed specifically for the 1979 to 1993 Mustang, so there’s no fuss. No two Mustang enthusiasts are exactly alike, so take some time and think about how YOU plan to enjoy YOUR Mustang. Fox custom style


Style is important. We all want the best-looking Mustang possible. The Fox Body Mustang is a clean, straightforward two-door design that lends itself well to style and appearance upgrades. With its long hood, short rear deck and relatively compact size, the Mustang continues the pony car style it created back in 1965. Adding your own signature to the exterior of your Mustang is easy with CJ Pony Parts. Consider:

• Custom hoods: Adding a custom hood with scoops and vents is a great way to differentiate your Mustang from the stock ones out there, while hinting at the performance under the hood.
• Rims and tires: Nothing catches the eye better than a shiny set of highly styled rims. Wider rubber fills out the wheel wells better and creates an intimidating stance.
• Decals and stripes: Recreate the look of legendary racing Mustangs with decal and stripe packages, or create your own original design with various Mustang-specific stickers.

Once you’ve taken care of the outside, it’s time to concentrate on your Mustang interior. If the exterior of the Fox Body is a timeless design, the interior can seem a little dated. Thankfully, we carry some great style add-ons and replacement parts for your interior that really improve on the original look, such as:

• Gauges: Modern, stylish digital gauge kits can totally change the look of your dashboard, with multiple finishes and lighting color choices available.
• Carpets: Wear and tear on your carpets can damage and dirty them. Our carpets are designed to fit perfectly in your cockpit and trunk, and we carry many choices in floor mats as well.
• Lighting: Adding custom lighting turns your Mustang into a show car! LED lights are an excellent way to add a bit of ambiance and highlight your improved interior.

Of course, there are many other ways to express your personal style and modify your Mustang. Custom trim panels, spoilers, headlights and taillights, and shift knobs are all easy to install Fox Body mods that will impress everyone who sees your car. There’s no end to the possible combinations, making it easy to build a truly unique Mustang that looks like no other.


Any older car is bound to have a few problems. With regular maintenance, you can keep your car running well, but some parts are eventually going to wear out. Installing upgraded parts in key areas can eliminate any surprises down the road. The result is a reliable, dependable car that doesn’t complain when you drive it hard. Take a look at your:

• Ignition: A new ignition is an absolute must with an upgraded engine. Even Mustang owners running a stock engine can benefit from improved drivability and reliability by upgrading the ignition, wires and plugs.
• Brakes: You don’t always get a lot of warning before your brakes wear down and start to fade. New high-quality pads, shoes, rotors and drums can boost your confidence in your braking system.
• Filters: With aftermarket filters for your oil and fuel, you can increase your performance, economy, and drivability — it’s a win on all fronts! We carry filters for many different Fox Body models and engines.

Knowing that your Mustang is going to fire up every time you turn the key is priceless. It doesn’t matter if your Mustang is a daily driver that you count on to get to work or a weekend warrior that only gets out to the track when the weather is nice. You want to be able to count on it. There are many other ways to modify your Fox Body so that it is the most reliable possible, including upgrading the:

• Lighting: Major advancements have been made in automotive lighting since the Fox Body came out. Upgrading your Mustang lights means you’ll have stronger, more dependable lighting that will last a long time.
• Carburetor: Some early Fox Body Mustangs came equipped with a carburetor, which can be notoriously difficult to adjust when they get old and dirty. A carb mod can increase performance and make your car more dependable.
• Battery and electrical: Rain, heat and wear can really degrade your electrical system over time. To avoid battery-related problems, replace your battery and alternator with higher performance solutions that are built to last.

As you see, many interesting and exciting reliability upgrades will also give you a boost in overall performance. Owning an older classic car such as the Fox Body Mustang is a pleasure, though it does require a bit more maintenance and attention than a new car. When you hit the road, hear that engine purr and feel yourself thrown back into your seat as you accelerate, you realize that it’s all worth it.
