April 21, 2024

Dive into the thrilling world of car customization. Today, we’ll talk about one aspect that often goes unnoticed but can greatly enhance your driving experience – the installation of an adjustable pedal box in a Ford Mustang. This guide is for anyone who has found themselves in the driver’s seat of a Mustang and felt the discomfort of the pedals being just out of perfect reach. By installing an adjustable pedal box, you can tailor the driving experience to match your height, enhancing both comfort and safety. Let’s get started.

Understanding the Basics: Pedals, Master Cylinder, and Rod Assembly

Before we delve into the installation process, it’s crucial to understand the fundamentals of your vehicle’s pedal assembly, including the throttle, clutch, and brake pedals, as well as the master cylinder and rod assembly.

The throttle, or accelerator pedal, controls the amount of air and fuel entering the engine. The brake pedal operates the master cylinder, which sends brake fluid to the brake calipers, causing the brake pads to clamp onto the rotors and slow the vehicle. The clutch pedal, found in manual vehicles, disengages the clutch, allowing for gear changes.

The master cylinder, located in the engine compartment, is a control device that converts non-hydraulic pressure (from your foot on the pedal) into hydraulic pressure to operate the brakes. The rod assembly connects the pedals to the master cylinder.

Choosing the Right Adjustable Pedal Box

Choosing the right adjustable pedal box is crucial for an optimal driving experience. These systems allow for fine-tuning of the pedals’ positions, making it easier for drivers of different heights to reach the pedals comfortably and safely.

A good pedal box will have options to adjust the height, reach (how far the pedal is from the seat), and the angle of the pedals. This level of adjustability ensures you can find the most comfortable position, reducing muscle strain and fatigue. Furthermore, these systems often incorporate a balance bar, allowing for individual adjustment of brake bias between the front and rear wheels.

When making your selection, take into account the quality of the materials, ease of installation, and whether it’s compatible with stock parts or requires additional parts for installation.

Steps for Installing the Adjustable Pedal Box

Installation of an adjustable pedal box isn’t overly complex if you have some mechanical aptitude. The main components involved are the pedal box assembly, master cylinder, clutch cable, brake pedal, and throttle cable.

Start the installation by removing the stock pedal assembly. First, disconnect the brake master cylinder and clutch cable from the existing assembly. Ensure to also disconnect the throttle cable. With these disconnected, you can remove the stock pedal box.

Next, prepare the adjustable pedal box for installation. Mount the master cylinder onto the pedal box assembly and connect the rod from the master cylinder to the brake pedal.

Once the pedal box is ready, you can install it into the car. Position the assembly in place and secure it using the provided fixings. It is important to ensure the pedal box is level and firm once installed.

After the pedal box is secured, you can reattach the clutch cable and throttle cable to the respective pedals.

Fine Tuning After Installation

Once the adjustable pedal box is installed, the work isn’t over. It’s now time to fine-tune the setup to ensure maximum comfort and performance.

Start by adjusting the height of the pedals. The goal here is to align the brake and throttle pedals for seamless foot transition. You’ll also want to adjust the reach, particularly if you’re shorter or taller than average.

Next, adjust the balance bar to modify the brake bias between the front and rear wheels. A car with a good brake balance will stop in a straight line when you apply the brakes, without the rear or front end dipping excessively.

Lastly, take the time to adjust the angle of the pedals. This might seem minor, but making sure your foot naturally rests against the pedal will lead to a more comfortable driving experience.

Remember, perfecting your setup might require a bit of trial and error. Don’t be afraid to make adjustments as needed, especially after a few test drives.

After reading this guide, we hope you now feel confident about installing an adjustable pedal box in your Ford Mustang. By customizing the pedal layout to match your height, you will enhance both your comfort and safety, making every drive more enjoyable. Happy motoring!

The Role of Supporting Components: Panhard Bar, Tie Rods, and Firewall Adjuster

Understanding the supporting components of a vehicle, such as the panhard bar, tie rods, and firewall adjuster, can contribute to the successful installation of your adjustable pedal box.

The panhard bar, also known as the track bar, is a vital component in the suspension system of your Ford Mustang. It assists in keeping the axle centered under the vehicle, preventing lateral movement. This plays a crucial role in ensuring the stability of the vehicle when braking, which is especially important after the installation of an adjustable pedal box.

The tie rods are integral to the steering system of your Mustang. They connect the steering system to the wheels, allowing the transfer of force from the steering center link or rack gear to the steering knuckle. This ensures that the wheels turn as you steer the vehicle. Maintaining the condition of the tie rods is key as any slackness can affect pedal response.

The firewall adjuster enables the driver to alter the clutch cable tension without getting under the vehicle. This is an essential feature to consider when installing the adjustable pedal box, especially if the vehicle is equipped with a manual transmission. The ability to adjust the clutch cable can further enhance the comfort and ease of driving for individuals of varying heights.

The Importance of Quality Master Cylinders and Pedal Pads

The heart of your Mustang’s brake system is the master cylinder. It’s where the process of transforming non-hydraulic pressure into hydraulic pressure happens, which allows your vehicle to stop when you step on the brake pedal. To ensure the new adjustable pedal box performs at its best, it’s advisable to invest in a quality master cylinder.

The pedal pads are what your feet come into contact with when you operate the pedals. They need to provide enough grip to prevent your foot from slipping off the pedal, especially in high-pressure situations. A quality pedal pad promotes more precise control over the throttle, brake, and clutch pedals, enhancing both safety and comfort.

Master cylinders and pedal pads from reputable brands like Maximum Motorsports can be trusted to deliver top-notch performance and durability.


Installing an adjustable pedal box in your Ford Mustang is not only about the thrill of customization but also about enhancing your driving experience. Understanding the importance of each component, from the panhard bar and tie rods to the master cylinders and pedal pads, can greatly contribute to the success of the installation. Remember that while the focus here is on the pedal box, other elements like the panhard bar, master cylinders, and tie rods play an equally essential role in your Mustang’s overall performance.

After the installation, take your time to fine-tune the pedal box for optimal comfort and safety. Remember, it’s not a process to be rushed but one to be savored. Enjoy the experience of customizing your Ford Mustang and making it uniquely yours. Drive with confidence, knowing you have installed the perfect adjustable pedal box for your driving comfort and safety. Happy motoring!
