2003 Acura CL Suspension Parts: A Complete Buyer’s Guide

If you own a 2003 Acura CL, you know it offers a balance of comfort and sporty handling. But after 20+ years, suspension components wear out, leading to a bouncy ride, uneven tire wear, or poor steering response. Replacing worn suspension parts can restore the car’s original feel or even improve it. This guide covers the key suspension parts for the 2003 Acura CL, what to look for when buying, and how to choose between OEM and aftermarket options.

Understanding the 2003 Acura CL Suspension System

The 2003 Acura CL uses a front MacPherson strut and rear multi-link independent suspension. This design offers good ride quality and handling, but it relies on many components that wear over time. Common parts that need replacement include:

• Struts and shocks – the main damping components
• Coil springs – support vehicle weight and absorb bumps
• Control arms – connect the wheel hub to the frame, with bushings that degrade
• Sway bar links – reduce body roll during cornering
• Ball joints – allow steering and suspension movement
• Tie rod ends – connect steering rack to wheels

Each part plays a role. If only one is worn, it can affect the whole system. It’s often wise to replace struts and shocks in pairs (front or rear) and consider replacing associated components like mount kits and bushings at the same time.

Signs Your 2003 Acura CL Needs Suspension Parts

Before buying parts, check for these symptoms:

• Excessive bouncing after bumps or a floaty highway ride
• Nose diving when braking or rear squatting during acceleration
• Uneven tire wear – cupping or bald spots on inner/outer edges
• Clunking or knocking noises when going over bumps or turning
• Steering wheel vibration or wandering on straight roads
• Vehicle leans heavily in corners
• Visible damage like leaking fluid from struts or cracked rubber boots

If you notice any of these, inspect the suspension components. Jack up the car and check for play in ball joints, tie rods, and bushings. Worn parts should be replaced promptly for safety and ride quality.

Key Suspension Parts for the 2003 Acura CL

Front Struts and Shock Assemblies

The front strut is a combined shock absorber and spring unit. For the 2003 Acura CL, you can choose between:

• Complete strut assemblies – pre-assembled with new spring, mount, and boot. Easier to install because you don’t need a spring compressor. Brands like Monroe, KYB, and Gabriel offer direct fit options.
• Individual struts – if your springs are still good, you can replace just the strut. Requires more labor but cheaper.

For a balance of comfort and control, KYB Excel-G struts are a popular replacement choice. If you want a sportier feel, Monroe OESpectrum offers firm damping. Avoid cheap no‑name brands that may not last.

Rear Shocks

The rear suspension uses separate shock absorbers (not struts). They are easier to replace. Again, KYB and Monroe are reliable. For a budget option, Gabriel Ultra shocks work well. If you lower the car, you’ll need shorter shocks designed for lowered springs.

Coil Springs

Over time, springs can sag, causing the car to sit unevenly or bottom out. For stock ride height, OE replacement springs from brands like Moog or AC Delco are fine. If you want a lowered stance (1–1.5 inches), consider Eibach Pro-Kit or H&R springs. Note: lowering springs usually require stiffer shocks to prevent bottoming out.

Control Arms and Bushings

Front lower control arms often have worn bushings that cause clunking and vague steering. You can replace just the bushing, but many shops recommend replacing the whole arm because the ball joint is often integrated. Moog and Mevotech make durable aftermarket control arms with greaseable ball joints and better bushings. Rear control arms (upper and lower) are also available; Mevotech’s TTX series is known for longevity.

Sway Bar Links

Sway bar links connect the stabilizer bar to the control arm or strut. They wear out and cause clicking noises. Replace both front and rear links if they’re loose. Moog and AC Delco are good choices. For a performance upgrade, consider adjustable links from Energy Suspension.

Ball Joints and Tie Rod Ends

Ball joints in the front lower control arms can separate if worn, causing loss of steering. Tie rod ends affect toe alignment and tire wear. Moog Problem Solvers feature forged housings and greaseable designs. Replace tie rods in pairs (inner and outer on each side) for even wear.

OEM vs. Aftermarket Suspension Parts

OEM (Original Equipment Manufacturer) Parts

• Pros: Exact fit, designed for stock ride quality, high quality from Acura.
• Cons: Expensive, often the same as aftermarket but with a premium price.
• When to choose: If you want to keep the car completely stock or need parts with warranty.

Aftermarket Parts

• Pros: Lower cost, often improved materials or design (e.g., polyurethane bushings, greasable ball joints). More options for performance upgrades.
• Cons: Some cheap brands may wear quickly, fitment issues rare but possible.
• When to choose: For replacement on a budget, or if you want to upgrade handling.

For daily driving, quality aftermarket parts from trusted brands (KYB, Monroe, Moog, Mevotech) are typically as good as OEM and cost less. For a performance build, brands like Koni, Eibach, or Bilstein offer superior dampening.

Installation Considerations

Replacing suspension parts requires mechanical skill and proper tools. You’ll need a spring compressor for strut assembly disassembly (if using separate components). After replacing any part that affects alignment (control arms, tie rods, struts), get a professional wheel alignment. Driving with misaligned suspension causes rapid tire wear and poor handling.

If you’re not comfortable with DIY, a mechanic can do the job. Labor costs vary, but expect around $150–$300 per axle for strut replacement plus alignment.

Recommended Suspension Upgrade for the 2003 Acura CL

For a plush daily driver, stick with KYB Excel-G struts and shocks paired with Moog control arms and sway bar links. This combination restores factory ride quality at an affordable price. If you drive aggressively or autocross, consider Koni Yellow adjustable shocks with Eibach Pro-Kit springs for a sporty but livable setup.

Final Recommendation

Your 2003 Acura CL’s suspension is likely showing its age. Start by inspecting and replacing any clearly worn components. For most owners, replacing front strut assemblies and rear shocks with KYB Excel-G, along with Moog front lower control arms and sway bar links, will dramatically improve ride comfort and safety. Always replace parts in pairs and get an alignment after work. Avoid cheap unbranded parts; invest in quality brands that have proven durability. With the right suspension parts, your 2003 Acura CL can drive like new again.
