KYB RC2223 Coil Spring

Product Overview

KYB RC2223 is a high‑performance coil spring designed for the front suspension of light‑to‑midweight vehicles, particularly those in the Nissan Almera II 3/5‑door family. Manufactured by KYB, one of the world’s leading automotive suspension suppliers, this component delivers reliable load support and precise ride characteristics.

Key Features

• K-Flex® Technology – The spring core is engineered with a proprietary alloy that provides excellent fatigue resistance while maintaining a lightweight profile.
• Optimized for front‑end suspension – The RC2223’s geometry and stiffness are tailored to the front axle layout of Nissan models, ensuring balanced handling and reduced body roll.
• Durable coiled construction – The spring is wound with a tight helix that offers consistent compression over thousands of cycles.
• Easy integration – Designed to fit standard mounting brackets and bushings used on the target vehicle platform, minimizing modification effort.

Technical Specifications

Applications and Compatibility

The KYB RC2223 is specifically engineered for the front suspension system of the Nissan Almera II. Its dimensions and mounting points match those found on the OEM coil spring, allowing a direct replacement without altering other components such as shock absorbers or control arms.

Because the spring’s stiffness profile aligns with the vehicle’s weight distribution, it is ideal for drivers seeking:

• Improved steering response
• Reduced body roll during cornering
• Consistent ride height under varying load conditions

Installation Guide

1. Safety First: Ensure the vehicle is securely lifted and supported on jack stands.
2. Remove the existing coil spring by loosening the mounting bolts on both ends and carefully extracting the spring from the suspension assembly.
3. Align the new RC2223 with the mounting brackets, ensuring that the coil’s orientation matches the OEM configuration.
4. Tighten the mounting bolts to the manufacturer’s specified torque (typically 70–80 Nm).
5. Reinstall any associated components such as shock absorbers or sway bars if they were removed during removal.
6. Lower the vehicle and perform a test drive to confirm proper operation and absence of abnormal noises.

Performance Benefits

When installed, the KYB RC2223 delivers:

• Enhanced handling dynamics – The spring’s precise rate reduces unwanted body movement, giving drivers a more connected feel to the road.
• Longer component life – The K-Flex alloy resists corrosion and fatigue, extending the service interval compared with standard springs.
• Consistent ride quality – Even under heavy loads or during aggressive driving, the spring maintains its compression characteristics, preventing sagging or excessive bounce.

Maintenance Tips

• Inspect the spring for visible damage such as dents or broken coils after any collision event.
• Check mounting bolts periodically to ensure they remain tight; loose bolts can lead to premature wear of suspension bushings.
• Keep the surrounding area clean from oil, grease, and debris that could accelerate corrosion.

Conclusion

The KYB RC2223 coil spring is a premium component engineered for the front suspension of the Nissan Almera II. Its K-Flex® construction, precise stiffness, and straightforward installation make it an excellent choice for drivers who demand reliable performance, durability, and superior handling characteristics.
