High-Quality OEM Replacement Front Upper Control Arm Pair

This front upper control arm pair is compatible with the following Cadillac models:

• Cadillac CTS (2008–2014) – Sedan, Coupe, and Wagon variants with 3.0L & 3.6L engines
• Cadillac SRX (2004–2009) – 3.6L V6 and 4.6L V8 models
• Cadillac STS (2005–2011) – 3.6L V6 and 4.6L V8 models

To confirm fitment, match the OE Part Numbers listed in our specifications with those on your original components, or contact us with your vehicle's VIN for verification before purchasing.

This complete front upper control arm pair includes:

• 1x Front Upper Control Arm – Left / Driver Side
• 1x Front Upper Control Arm – Right / Passenger Side
• Pre-installed Ball Joints (Press-In mounting with threaded stud) on both arms
• Pre-installed and Pre-Greased Bushings on both arms — ready for immediate installation

No additional components or hardware are required. Both arms arrive fully assembled and ready for fitment.

Pre-greased bushings offer several key benefits:

• Immediate Installation: No need to apply grease separately — the arms are ready to fit straight out of the box
• Optimal Lubrication: Factory-applied grease ensures the correct quantity and distribution for long-term bushing performance
• Reduced Wear: Proper lubrication minimises bushing wear and reduces noise, vibration, and harshness (NVH) over time
• Consistency: Ensures every unit leaves with the same quality standard, reducing variability during installation

High-grade cast aluminium is the preferred material for premium upper control arms for several reasons:

• Lightweight Strength: Aluminium provides an excellent strength-to-weight ratio, reducing unsprung weight without sacrificing structural integrity
• Corrosion Resistance: Unlike steel, aluminium naturally resists rust and corrosion, extending the service life of the component
• Improved Handling: Lower unsprung weight improves suspension response, steering feel, and overall ride quality
• OEM Match: The original Cadillac factory components on these platforms use cast aluminium — this replacement matches that specification exactly

Upper Control Arms connect the top of the wheel hub/knuckle to the vehicle's frame or subframe. They primarily control camber angle and help guide the wheel through its travel during suspension compression and rebound.

Lower Control Arms connect the bottom of the wheel hub to the chassis and carry a greater share of the suspension load, handling braking, acceleration, and lateral forces.

Both arms work together as part of the double-wishbone or multi-link suspension system to maintain proper wheel geometry, tyre contact, and ride stability throughout all driving conditions.

Self-installation is not recommended for this product. Professional installation by a qualified technician is strongly recommended for the following reasons:

• Correct torque specifications must be applied to all fasteners for safe suspension operation
• Specialised tools are required to safely remove and install press-in ball joints and bushings
• Proper suspension geometry and alignment must be restored after installation
• Incorrect installation can compromise steering safety and handling performance

Note: Installation instructions are not included with this product. Professional installation is also required to activate the 10-Year Extended Warranty.

Yes — a professional wheel alignment is essential after replacing upper control arms. The upper control arm directly influences camber and caster angles, which affect tyre contact, steering response, and handling balance.

Without a proper alignment, you may experience uneven tyre wear, steering pull, or reduced handling performance. Your technician should perform a four-wheel alignment immediately following installation to restore factory suspension geometry.

Common signs of worn or failing front upper control arms include:

• Clunking or knocking sounds from the front suspension, especially over bumps
• Excessive vibration or shimmy through the steering wheel
• Uneven or abnormal tyre wear — particularly inner or outer edge wear
• Vague, wandering, or imprecise steering feel
• Vehicle pulling to one side during acceleration or braking
• Difficulty maintaining a wheel alignment
• Visible bushing cracking, tearing, or corrosion on the arm body

If you experience any of these symptoms, have your suspension inspected by a qualified technician without delay.

We offer two warranty levels:

• 10-Year Extended Warranty: Activated when the product is installed by a fully qualified professional. You must submit a copy of your garage fitment invoice within 30 days of installation to activate this coverage.
• 1-Year Standard Warranty: Applies by default if no garage invoice is submitted within 30 days of purchase.

All warranty coverage applies to the product only and excludes labour costs, installation charges, or any additional expenses incurred.

These are high-quality aftermarket replacement parts engineered to meet or exceed OEM (Original Equipment Manufacturer) specifications. They are 100% brand new and designed as direct replacements for your factory upper control arms.

Manufactured from the same high-grade cast aluminium as the original Cadillac components, they provide the same fit, function, and performance as factory parts — with the added convenience of pre-installed, pre-greased hardware for a faster installation process.

To confirm 100% compatibility before purchasing, follow these steps:

• Check Make, Model & Year: Confirm your vehicle is a Cadillac CTS (2008–2014), SRX (2004–2009), or STS (2005–2011)
• Verify Engine Size: Ensure your engine matches the listed options (3.0L, 3.6L V6, or 4.6L V8)
• Match OE Part Numbers: Compare the part numbers in our specifications against those on your original control arm components
• Contact Us with Your VIN: Our team can use your Vehicle Identification Number to confirm exact fitment before you order
