KYB SM5655 - Strut Mount, Black
What the SM5655 Kit Includes
The KYB SM5655 is a complete strut mounting kit that typically contains:
- Strut mount (bearing plate) – Allows the strut to rotate with steering while absorbing vertical loads.
- Rubber isolator – Cushions the connection between the strut and vehicle body, reducing noise and vibration.
- Retaining nuts and washers – Secures the strut piston rod to the mount.
- Upper seat – Supports the coil spring top.
Some kits may also include a dust cap or additional hardware depending on the vehicle application. Always verify the contents against the manufacturer's official listing for your specific model.
Vehicle Compatibility for KYB SM5655
This kit is designed for a specific range of vehicles. Common applications include:
- Honda Accord (1990–1997)
- Honda Civic (1992–2000)
- Acura Integra (1994–2001)
- Acura CL (1997–1999)
- Honda Prelude (1992–1996)
Compatibility can vary by year and trim level. To confirm fitment, check your vehicle's original equipment part number or consult a suspension catalog. Using the correct mounting kit ensures proper alignment of the strut assembly and prevents premature wear.
Why Choose KYB for Strut Mounts?
KYB is a leading original equipment (OE) supplier for many automakers. Their strut mounts are engineered to meet or exceed factory specifications. Key advantages:
- Precision engineering – Bearings are pre-lubricated and sealed to reduce friction and extend lifespan.
- Durability – Rubber components are formulated to resist cracking and ozone damage.
- Ease of installation – Kits are designed to bolt directly in place without modification.
- Quiet operation – Proper isolation prevents clunks and rattles from the suspension.
Compared to generic aftermarket mounts, KYB typically offers better materials and fitment accuracy. However, always inspect old parts to confirm the mount design matches.
Installation Tips for the SM5655 Kit
Proper installation is crucial for safety and performance. Consider these practical steps:
Preparation
- Jack up the vehicle and secure it on jack stands.
- Remove the wheel and support the lower control arm.
- Mark the position of the top nut and washer if reuse is planned (though new hardware is included).
Removing the Old Mount
- Compress the coil spring using a spring compressor before disassembling the strut.
- Remove the center nut while holding the piston rod from turning.
- Lift off the old mount and isolator.
Installing the New Kit
- Place the new upper seat onto the spring.
- Align the rubber isolator and mount; ensure the bearing rotates freely.
- Install the retaining nut and torque to manufacturer specifications (typically 35–50 ft-lbs, but verify).
- Reassemble the strut assembly carefully, releasing spring compressor evenly.
Final Steps
- Reinstall the strut assembly into the vehicle.
- Tighten the top mounting nuts to the recommended torque (check service manual).
- Reattach the wheel and lower the car. A alignment check is recommended after suspension work.
How to Spot a Worn Strut Mount
Signs that your strut mount needs replacement include:
- Clunking or knocking noises from the front or rear suspension.
- Excessive steering play or vibration.
- Uneven tire wear.
- Visible cracking or rust on the mount.
- The strut piston rod appears loose or off-center.
If you're already replacing struts, it's cost-effective to replace the mounts at the same time, as the labor overlaps.
Comparing KYB SM5655 to Other Options
While KYB is a strong choice, consider these points when comparing with competitors:
- OEM vs. aftermarket – KYB is often the same as OEM but at a lower price. Other quality brands include Monroe and Sachs.
- Bearing design – Some budget mounts use solid rubber tops that lack a bearing, causing steering stiffness. KYB uses a sealed bearing.
- Warranty – KYB offers a limited lifetime warranty on many products, check terms.
For most daily drivers, the SM5655 kit offers a balanced blend of quality and value. However, if your car sees heavy track use or extreme conditions, you might consider a race-oriented solid mount.
Practical Recommendation
Given its OE heritage, precise fitment, and durable construction, the KYB SM5655 strut mounting kit is a reliable choice for owners of compatible Honda and Acura models. It eliminates common suspension noises and restores proper alignment geometry. For a smooth, trouble-free installation, pair this kit with new KYB struts (such as Excel-G) and quality spring compressors. If you're unsure about compatibility, verify your vehicle's year and model against the official KYB application guide before purchasing. Investing in a proper mount kit like the SM5655 will extend the life of your new struts and keep your suspension performing as intended.
