Why Install a Front Strut Bar on Your Acura TLX?

The front strut bar is designed to stiffen the front suspension assembly by linking the two strut towers located in the engine bay. Here are some of the key benefits you can expect from this upgrade:

  • Improved Chassis Rigidity: The strut bar reduces flex between the strut towers under lateral loads, making the front end more stable during aggressive cornering.
  • Reduced Body Roll: By limiting chassis flex, the car experiences less lean or roll during turns, resulting in better balance and more predictable handling.
  • Enhanced Steering Response: With the strut towers connected, steering inputs translate more directly to the wheels without unwanted flex or delay.
  • Better Tire Contact: Consistent suspension geometry helps maintain optimal tire contact with the road, improving grip and traction.
  • Simple, Cost-Effective Modification: Compared to suspension overhauls or aftermarket sway bars, installing a strut bar is quick, reversible, and relatively inexpensive.

While the 2020 Acura TLX already features a well-engineered suspension setup, adding a strut bar is a popular and practical way to further enhance its dynamic capabilities without compromising ride comfort.

Choosing the Right Front Strut Bar for the 2020 Acura TLX

Before starting the installation, it’s essential to select a strut bar that is specifically designed for the 2020 Acura TLX to ensure proper fitment and functionality. Here are some considerations when choosing your strut bar:

  • Material: Most strut bars are made from aluminum or steel. Aluminum offers light weight and corrosion resistance, while steel provides extra strength but may add weight.
  • Design: Common designs include single-piece bars and adjustable multi-piece bars. Adjustable bars allow fine-tuning for different suspension setups.
  • Finish: Powder coating or anodizing protects the bar from rust and wear, while also enhancing engine bay aesthetics.
  • Brand Reputation: Opt for reputable manufacturers with positive reviews and proven fitment for the Acura TLX.
  • Compatibility with Other Mods: Ensure the strut bar does not interfere with aftermarket components such as cold air intakes, turbochargers, or engine covers.

Tools and Materials Needed

  • Front strut bar designed for the 2020 Acura TLX
  • Socket wrench set (metric sizes typically 12mm or 14mm)
  • Torque wrench (capable of measuring recommended torque in Nm or ft-lbs)
  • Jack and jack stands (optional but recommended for better access)
  • Protective gloves to safeguard your hands
  • Soft cloth or microfiber towel (to protect paint and components)
  • Anti-seize lubricant (optional, to prevent nuts and bolts from seizing)

Preparation Before Installation

Proper preparation is key to a smooth and safe installation process. Follow these guidelines before beginning:

  • Park on a Flat Surface: Ensure your Acura TLX is parked on level ground and the parking brake is engaged to prevent movement.
  • Turn Off the Engine: Allow the engine bay to cool for at least 30 minutes if the car was recently driven to avoid burns.
  • Disconnect the Battery (Optional): For added safety, disconnect the negative terminal of the battery to prevent accidental electrical shorts, especially if working near electrical components.
  • Gather Tools and Components: Organize all tools and the strut bar kit within easy reach.
  • Wear Protective Gear: Gloves and safety glasses will protect your hands and eyes from dirt and debris.

Step-by-Step Installation Process

  1. Raise the Front of the Vehicle (Optional):
    Using a hydraulic jack, lift the front of your Acura TLX and secure it on jack stands. This provides better access to the strut towers and components in the engine bay. If you prefer, installation can be done without lifting the car but may be slightly more challenging.
  2. Open the Hood and Locate the Front Strut Towers:
    The strut towers are the circular metal structures on either side of the engine bay, directly above the front suspension struts. On the 2020 TLX, they are easily identifiable with three mounting studs protruding from each tower.
  3. Clean the Strut Tower Areas:
    Use a clean cloth to wipe dirt and debris around the mounting studs. This will ensure a snug and clean fit for the strut bar and prevent scratching.
  4. Remove the Nuts from the Strut Mounts:
    Using a socket wrench and the appropriate socket size, carefully remove the three nuts securing each strut mount. Place the nuts in a safe container as you will reinstall them later.
  5. Position the Front Strut Bar:
    Align the strut bar’s mounting holes over the studs on both strut towers. The bar should rest flush against the towers without forcing or bending.
  6. Reinstall the Nuts by Hand:
    Thread the original nuts back onto the studs over the strut bar mounts by hand. This helps prevent cross-threading and ensures proper alignment.
  7. Tighten the Nuts with a Socket Wrench:
    Using the socket wrench, snug the nuts evenly on both sides, alternating between them to maintain balanced pressure.
  8. Torque the Nuts to Manufacturer Specifications:
    Consult the strut bar manufacturer’s instructions or your Acura TLX service manual for the correct torque specification—typically around 35 to 50 ft-lbs (47 to 68 Nm). Use a torque wrench to tighten the nuts evenly and accurately to avoid over-tightening, which can damage components.
  9. Inspect the Installation:
    Double-check that the strut bar is firmly mounted and that there is adequate clearance around engine components, wiring, and hoses. Ensure the bar does not interfere with the hood when closed.
  10. Lower the Vehicle (If Raised):
    Carefully remove the jack stands and lower your Acura TLX back to the ground.
  11. Reconnect the Battery (If Disconnected):
    Reattach the negative battery terminal and tighten securely.

Post-Installation Checks and Maintenance

After installation, it’s important to monitor the strut bar’s condition and mounting hardware to ensure ongoing performance and safety:

  • Test Drive: Take your TLX for a cautious test drive, paying attention to handling improvements and any unusual noises or vibrations.
  • Recheck Torque: After the first 100 miles, re-torque the strut bar nuts to confirm they remain properly tightened.
  • Regular Inspections: During routine maintenance, visually inspect the strut bar for signs of corrosion, cracks, or looseness.
  • Cleaning: Wipe down the strut bar with a damp cloth to keep it free from dust and grime, which can affect its finish and longevity.

Additional Tips and Considerations

Compatibility with Other Suspension Upgrades

If you plan to upgrade other suspension components such as sway bars, coilovers, or bushings, installing a front strut bar is a complementary modification that can further enhance chassis stiffness. However, it’s advisable to install the strut bar first and evaluate the handling before adding other parts, to better understand the incremental benefits.

Potential Impact on Ride Comfort

While a strut bar improves handling by stiffening the chassis, it typically has minimal impact on ride comfort. However, in some cases, drivers may notice a slightly firmer feel over bumps due to reduced chassis flex. This trade-off is often appreciated by enthusiasts seeking sharper driving dynamics.

Choosing Between Front Only or Front and Rear Strut Bars

Some Acura TLX owners choose to install both front and rear strut bars for maximum chassis reinforcement. Rear strut bars connect the rear suspension strut towers and provide similar benefits in rear-end stability. If your driving style involves aggressive cornering or track use, considering both bars can be worthwhile.

Professional Installation

While installing a front strut bar is generally a straightforward DIY task, if you are unfamiliar with automotive tools or uncomfortable working under the hood, seeking professional installation is recommended. A qualified mechanic can ensure the strut bar is installed correctly and safely.
