Understanding the 2017 F150 Upper Control Arm
The upper control arm on a 2017 Ford F150 is a vital suspension component connecting the frame to the steering knuckle. Its primary function is to manage wheel movement and maintain proper alignment, ensuring stable handling and even tire wear. When considering upgrades or replacements, understanding its geometry and interaction with other suspension parts is paramount.
- Controls wheel travel and steering geometry.
- Essential for proper suspension alignment.
- Directly impacts tire wear and handling.
- Affected by lift kits and aggressive driving.
This component, often made of stamped steel or forged aluminum on newer models for weight savings and strength, acts as a pivot point. It allows the wheel assembly to move up and down while maintaining its position relative to the chassis. The pivot points at the frame and the knuckle are typically fitted with bushings and ball joints, which are critical to its smooth operation and longevity. Worn bushings or a damaged arm can lead to significant handling issues.
Core Functionality
The core principle behind the upper control arm's design is to maintain caster and camber angles within specified tolerances. Caster influences steering stability, while camber affects how the tire contacts the road during turns. A properly functioning 2017 F150 upper control arm ensures that as the suspension compresses or extends, these critical alignment angles remain as close to their intended settings as possible. This mechanism is critical for predictable steering and responsive road feel, especially under dynamic driving conditions.
When Upgrades Become Necessary
While the stock control arm is designed for everyday use, certain modifications or driving habits necessitate an upgrade. Installing a suspension lift kit, for instance, alters the suspension geometry, often placing the stock upper control arm at an extreme angle. This can cause binding, premature wear on ball joints and bushings, and make achieving proper alignment difficult. Similarly, off-roading or towing heavy loads can put excessive stress on the component, leading to potential failure or accelerated wear. Understanding this principle is fundamental to preventing costly damage.
For many 2017 F150 owners, especially those venturing beyond mild off-roading or looking to correct alignment after a lift, an adjustable upper control arm becomes a worthwhile consideration.
Consider the impact of driving conditions on your truck's suspension.
Pros of Upgrading Your 2017 F150 Upper Control Arm
What are the advantages when you decide to swap out the factory upper control arm on your 2017 Ford F150?
Enhanced Alignment Capabilities
The most significant benefit of upgrading to an adjustable upper control arm is the vastly improved ability to achieve and maintain correct wheel alignment. When a lift kit is installed, the suspension geometry changes, often pushing the wheel forward or backward and altering camber and caster angles beyond the factory adjustment range. Adjustable control arms allow technicians to precisely dial in these angles, ensuring proper alignment even with significant suspension modifications. This is crucial for restoring factory steering feel and preventing uneven tire wear, a common issue with lifted trucks.
Improved Durability and Strength
Many aftermarket upper control arms are constructed from stronger materials like forged aluminum or thicker steel than their stock counterparts. They often feature upgraded ball joints and more robust bushings designed to withstand greater stress. This increased durability makes them ideal for trucks that see aggressive off-road use, frequent towing, or carry heavy loads. Such precision is paramount for components subjected to extreme forces.
Inspect your bushings for signs of wear regularly.
Correction for Lifted Suspensions
For trucks lifted more than 2-3 inches, stock control arms are often at an angle that compromises suspension travel and alignment. An aftermarket upper control arm is typically designed with a corrected geometry to bring the angles back closer to their original range. This allows for better suspension droop, prevents the ball joint from binding at extreme angles, and makes achieving a proper alignment achievable. Without this correction, achieving correct alignment is often impossible.
Install adjustable upper control arms simultaneously with your lift kit to prevent the need for realignment once the suspension settles.
Better Steering Feel and Response
With proper alignment restored and stronger components in place, drivers often report a noticeable improvement in steering feel. The truck feels more stable, less prone to wandering, and steering inputs are more precise. This is especially true if the original control arm bushings were worn, leading to a vague or loose feeling in the steering wheel. Our analysis indicates that this upgrade directly contributes to a more connected driving experience.
The difference can be night and day for your driving confidence.
Cons and Considerations for F150 Upper Control Arms
What are the potential drawbacks and crucial points to consider before committing to a 2017 Ford F150 upper control arm upgrade?
Increased Cost
Aftermarket upper control arms, particularly adjustable or high-strength forged options, represent a significant investment. While stock replacements might cost a few hundred dollars, a quality set of adjustable arms can easily range from $500 to over $1000, not including installation. This cost needs to be weighed against the benefits, especially if your truck isn't heavily modified or used in extreme conditions. The primary consideration involves your budget and intended use.
Alignment Complexity and Cost
While adjustable arms *enable* better alignment, they also make the alignment process more complex and potentially more expensive. A standard alignment shop might not have the experience or tools to properly adjust aftermarket arms, especially for significant lift heights. You'll likely need to find a shop specializing in lifted trucks or custom alignments. Furthermore, because the angles can be easily changed, they may require more frequent checks, particularly after hard off-roading.
Ensure your chosen shop has experience with custom alignments.
Potential for Noise and Vibration
Some aftermarket control arms, especially those using more rigid or performance-oriented bushings (like polyurethane or uniballs), can transmit more road noise and vibration into the cabin compared to stock rubber bushings. While this is often a trade-off for increased durability and performance, it's something to consider if cabin comfort is a top priority. It is imperative to acknowledge this potential shift in NVH (Noise, Vibration, Harshness) levels.
Choosing the right control arm balances performance needs with everyday drivability.
Compatibility Issues
Not all aftermarket upper control arms are created equal, and compatibility with specific lift kits, wheel offsets, or tire sizes can be an issue. It is crucial to research thoroughly and ensure the chosen part is designed for your specific 2017 F150 configuration and intended use. Failing to do so can lead to fitment problems, requiring additional modifications or returns. This mechanism is critical for ensuring proper integration without unforeseen complications.
Never assume an aftermarket part will fit without verification.
Verdict: Is an Upgrade Right for Your 2017 F150?
For the average 2017 Ford F150 owner whose truck remains close to stock height and sees mostly on-road use, the stock upper control arms are generally sufficient and durable. However, if you plan to install a suspension lift of 2 inches or more, engage in regular off-roading, or frequently tow heavy loads, upgrading to a quality adjustable upper control arm set is highly recommended. It's an investment that restores proper alignment, enhances durability, and improves the overall driving experience, preventing more costly repairs down the line. The decision hinges on your truck's intended use and modifications.
