A vehicle's suspension system is responsible for maintaining good road contact, absorbing shocks, and controlling vehicle movements. The upper control arm is a crucial part of the suspension, as it connects the spindle (the part that holds the wheel) to the chassis. Its position and geometry affect the vehicle's alignment, stability, and handling characteristics. In the case of the 2005-2014 Ford Mustang, the stock rear upper control arm is prone to flexing under hard acceleration or cornering, leading to wheel hop, inconsistent handling, and less than optimal performance.
Upgrading to an aftermarket rear upper control arm can address these issues and take the driving experience of your Mustang to the next level. The benefits of an upgraded rear upper control arm include improved traction, reduced body roll, better cornering, and quicker throttle response. Aftermarket rear upper control arms are typically made of stronger and lighter materials, such as aluminum or chromoly steel, and feature adjustable design for precise tuning. They also have stiffer bushings or bearings that provide more precise and consistent alignment, reducing the chance of wheel hop and improving launch performance.
When choosing an aftermarket rear upper control arm for your Mustang, it's important to consider factors such as the intended use, the level of adjustability, and the material and construction quality. Some popular brands that offer rear upper control arms for the 2005-2014 Ford Mustang include Steeda, BMR Suspension, Maximum Motorsports, and Whiteline. These brands are known for their high-quality components that are designed for performance and durability.
Installing a rear upper control arm on your Mustang is not a difficult task and can be done with basic hand tools. However, it does require some suspension knowledge and skill, as well as proper alignment after installation. It's recommended to consult a professional mechanic or suspension specialist if you're not comfortable with doing the installation yourself.
In summary, upgrading the rear upper control arm of your 2005-2014 Ford Mustang can significantly improve its handling and performance. An aftermarket rear upper control arm can provide better stability, traction, and responsiveness, while also reducing wheel hop and body roll. Brands like Steeda, BMR Suspension, Maximum Motorsports, and Whiteline offer high-quality rear upper control arms that are well-designed and manufactured to enhance your Mustang's suspension system. If you want to get your Mustang hooked up and handling great, upgrading the rear upper control arm should be on your to-do list.
