Immediate Answer: Which Suspension Parts Fit Your Acura CL?
Both generations of the Acura CL use unique suspension layouts and components, and not all parts are cross-compatible. OEM (Original Equipment Manufacturer) suspension parts guarantee direct fitment and retain factory ride characteristics. Aftermarket options, meanwhile, offer customization for performance or comfort but may require careful selection and installation to avoid fitment or safety issues.
- First Generation (1997–1999): Uses a double-wishbone front and rear suspension. Most OEM and reputable aftermarket brands offer direct-fit struts, shocks, and bushings.
- Second Generation (2001–2003): Features a MacPherson strut front and multi-link rear suspension. Suspension geometry differs from the previous generation, making cross-fitment impossible without major modification.
Key fitment fact: Always match your suspension components to your Acura CL’s generation, trim level, and VIN for guaranteed compatibility. Aftermarket kits must specify direct fitment for your model year and body style.
Hidden Problem: Why Suspension Fitment Is More Complex Than It Seems
Owners often assume that all Acura CL suspension parts are interchangeable or that aftermarket upgrades will fit “out of the box.” In reality, even small differences in model year, trim, or market specification can affect mounting points, dampening rates, and ride height. Misfit parts can cause:
- Poor handling and unpredictable alignment
- Premature tire and bushing wear
- Safety system malfunctions (e.g., ABS, traction control)
- Compromised ride comfort or excessive noise
Additionally, aftermarket suspension kits may provide “universal” fitment claims that do not account for the Acura CL’s specific geometry, especially in the transition from double-wishbone to MacPherson strut designs between generations. This complexity is compounded by the proliferation of low-quality aftermarket parts that may not meet NHTSA equipment safety standards.
Understanding Acura CL Suspension Architecture
First Generation (1997–1999): Double-Wishbone Excellence
The first-generation Acura CL is built on a double-wishbone suspension system both front and rear, a hallmark of Honda/Acura engineering from the 1990s. This layout provides:
- Superior camber control during cornering
- A more predictable ride and handling envelope
- Increased suspension articulation for better tire contact
OEM Fitment: Direct-fit struts, shocks, and bushings are available from Honda/Acura and several high-quality aftermarket brands. Lower control arms and ball joints are model-specific.
Second Generation (2001–2003): MacPherson and Multi-Link
The second-generation CL adopts a MacPherson strut front and multi-link rear suspension. This change was made for packaging efficiency and improved ride comfort at the expense of some handling sharpness.
- Front: MacPherson struts are more compact but have different mounting points and geometry than double-wishbone setups.
- Rear: Multi-link provides a good balance of comfort and handling, but each link and bushing must be matched precisely to the model year and trim.
OEM Fitment: Struts, springs, and bushings must be purchased for the correct generation. Aftermarket coilovers or lowering springs must specify fitment for 2001–2003 models.
OEM vs. Aftermarket Suspension: Pros, Cons, and Fitment Realities

- Oversized sway bars without matching end links can cause premature wear or noise.
Polyurethane Bushings
- Offer improved response and longevity over rubber but may increase noise and vibration.
- Ensure bushing kits specify compatibility with your suspension type (double-wishbone or multi-link).
Strut Braces
- Front and rear strut tower braces are popular upgrades but must be designed for your Acura CL’s chassis layout.
Common Pitfalls: Avoiding Costly Fitment Mistakes
Cross-Generation Mixing
- First and second-generation CL suspension components are not interchangeable.
- Attempting to fit double-wishbone parts on a MacPherson-equipped car (or vice versa) will result in mounting and geometry issues.
“Universal” Aftermarket Kits
- Universal coilovers, springs, or bushings rarely fit correctly without extensive modification.
- Always verify that the manufacturer lists your exact year, model, and trim.
Used or Salvage Parts
- Used OEM parts may have unknown wear or damage, especially bushings and shocks.
- If sourcing from salvage, inspect for rust, cracks, and bushing integrity.
Technical Deep Dive: Suspension Materials and Performance
Suspension performance isn’t just about geometry—it’s also about materials and construction. Premium aftermarket brands may use advanced materials such as high-strength steel, aluminum, or composite bushings, which can improve strength and reduce weight. According to the U.S. Department of Energy’s Materials Technologies, lighter and stronger materials contribute to both handling and fuel efficiency.
OEM vs. Aftermarket:
- OEM arms and links are typically stamped steel or cast aluminum, optimized for durability.
- Aftermarket performance arms may use tubular steel or billet aluminum for reduced weight and added rigidity, but only if properly engineered for your Acura CL’s loads and geometry.
Safety Considerations: Meeting Standards and Regulations
All suspension parts should comply with NHTSA equipment safety standards. Substandard or ill-fitting components can compromise safety systems, including:
- ABS and traction control sensors (affected by ride height and geometry)
- Structural integrity in collisions (mounting points must remain secure)
- Predictable handling and emergency maneuvering
Always check for manufacturer documentation of compliance with SAE or NHTSA standards, especially for critical components such as struts, control arms, and bushings.
