2005 Acura TSX Suspension Parts: A Complete Guide to Replacement and Upgrades

The 2005 Acura TSX was praised for its sharp handling and refined ride, but after nearly two decades, suspension components inevitably wear out. Whether you're chasing worn bushings, sagging springs, or blown struts, choosing the right parts for your TSX can restore its original balance or upgrade it for more aggressive driving. This guide covers the key suspension parts, what fails most often, and how to choose between OEM and aftermarket options.

Common Suspension Issues on the 2005 Acura TSX

The TSX uses a double-wishbone front suspension and multi-link rear setup. Over time, the following parts tend to fail:

Front Lower Control Arms

• The rear bushing in the front lower control arm is a known weak point. When it cracks or tears, you'll notice clunking over bumps and vague steering.
• Many owners replace the entire control arm rather than pressing in a new bushing, as the labor cost often justifies the complete assembly.

Struts and Shocks

• Front struts and rear shocks lose damping ability around 80,000–100,000 miles. Symptoms include excessive bouncing, nose dive under braking, and poor cornering.
• Leaking fluid is a clear sign the shock is dead.

Sway Bar Links and Bushings

• End links wear out and cause rattling over bumps. Sway bar bushings dry out and allow bar movement, making the car feel sloppy in turns.

Ball Joints and Tie Rods

• Front ball joints can develop play, leading to steering wander and uneven tire wear.
• Tie rod ends are less common but should be inspected if steering feels loose.

OEM vs Aftermarket: Which Suspension Parts Should You Choose?

OEM Parts

• Honda/Acura genuine parts offer exact fit and the same ride quality as original.
• Best if you want the car to drive like new and plan to keep it long-term.
• More expensive, but often include a warranty.

Aftermarket Options

• KYB makes OE-quality struts for the TSX (Excel-G for stock replacement).
• Moog is popular for control arms and tie rods, often with improved grease fittings.
• Koni offers adjustable shocks for those who want to fine-tune handling.
• Eibach and H&R make lowering springs that maintain good ride comfort.
• For bushings, consider Energy Suspension or Whiteline polyurethane for tighter feel and longer life, but note they can increase NVH (noise, vibration, harshness).

Cost Comparison

• A full set of OEM front struts can run $300–400 for parts alone.
• Aftermarket KYB struts are about $150–200 for the pair.
• Control arms: OEM ~$200 each; Moog ~$80–100.
• Poly bushings add $50–100 if you press them into original arms.

Step-by-Step Guide: Parts Replacement Order

If you're tackling the job yourself, follow this order to avoid repeating work:

1. Replace front struts – Remove as a unit or use spring compressors.
2. Replace front lower control arms – New arm includes ball joint and rear bushing.
3. Replace sway bar links and bushings – Simple, cheap, and makes a big difference.
4. Replace rear shocks – Accessible from the trunk.
5. Check and replace tie rod ends – Do before an alignment.
6. Swap rear trailing arm bushings if they are torn – Common on high-mileage cars.

After any suspension work, a professional alignment is necessary. Expect to pay $80–120 for a four-wheel alignment.

Recommended Suspension Upgrades for the 2005 Acura TSX

For Daily Driving

• Stay with OEM or KYB struts/shocks with fresh springs (if sagged).
• Replace control arm bushings with OEM rubber for comfort.
• Use standard replacement parts from a trusted brand like Beck/Arnley or Moog.

For Slightly Sportier Handling

• Install Koni STR.T shocks (red) – slightly stiffer than stock but still compliant.
• Pair with Eibach Pro-Kit springs – lower the car about 1 inch without ruining ride quality.
• Upgrade sway bar end links to Moog greasable units.
• Add a Progress or Whiteline rear sway bar to reduce understeer.

For Track or Autocross

• Koni Yellow adjustable shocks – you can set rebound stiffness.
• Ground Control coilover sleeves or full Tein coilovers for adjustability and lower center of gravity.
• Polyurethane bushings throughout your control arms and rear subframe.
• Camber kits may be needed to keep alignment in spec after lowering.

Where to Buy 2005 Acura TSX Suspension Parts

While we don't name specific marketplaces, you can find these parts at national auto parts chains, specialty import parts retailers, or from Acura dealerships. Always verify fitment with your VIN before ordering. Look for brands that offer a good warranty—lifetime on ball joints and tie rods is common from aftermarket suppliers.

Final Recommendation

For most 2005 Acura TSX owners, a mix of OEM-grade and aftermarket parts works best. Replace worn struts with KYB Excel-G for a stock-like ride, and use Moog control arms and sway bar links for durability at a fair price. If you want improved handling without harshness, add Eibach Pro-Kit springs and Koni STR.T shocks. Always replace suspension parts in pairs (both fronts or both rears) to keep handling balanced. Invest in a quality alignment after all work—small changes in geometry can make or break how the car drives. Your 2005 TSX will thank you with crisp, responsive handling for years to come.
