• Durable Coating: Corrosion‑resistant finish protects against harsh environments, extending service life.
• Easy Installation: Standard mounting dimensions allow direct replacement of OEM coil springs without modification.

Technical Specifications

Performance Benefits

The RA1896 coil spring is engineered to provide a balanced blend of stiffness and compliance. This results in:

• Improved Handling: Reduced body roll during cornering enhances steering precision.
• Enhanced Comfort: Smooth absorption of road irregularities minimizes vibration transmission to the cabin.
• Consistent Ride Height: Maintains optimal suspension geometry, preserving tire contact patches and braking performance.
• Long-Term Reliability: High fatigue resistance ensures minimal spring deflection over thousands of cycles.

Installation Guide

Installing the KYB RA1896 Coil Spring is straightforward for technicians familiar with front‑axle suspension systems. Follow these steps to ensure proper fitment:

1. Preparation: Secure the vehicle on a lift or jack stands and remove the wheel assembly.
2. Remove Existing Spring: Detach the current coil spring from its mounting brackets, noting orientation for correct reassembly.
3. Mount the RA1896: Align the new spring with the mounting points. Use a torque wrench to tighten bolts to the manufacturer’s specified values (typically 80–100 Nm).
4. Reinstall Wheel Assembly: Reattach the wheel and lower the vehicle.
5. Test Ride: Perform a short drive to confirm smooth operation and correct ride height.

Compatibility Overview

The RA1896 is designed for front‑axle applications in a variety of passenger vehicles, including but not limited to:

• Sedan and Compact Cars: Models requiring moderate load capacity and compact suspension travel.
• Crossover SUVs: Vehicles with higher ground clearance that benefit from the spring’s durability.
• Light Commercial Vehicles: Applications where consistent ride height under varying payloads is critical.

Always verify vehicle specifications and consult the manufacturer’s part number cross‑reference chart before installation.

Maintenance Tips

• Inspect for visible damage such as cracks or excessive wear after major impacts.
• Check mounting bolts periodically to ensure they remain tightened within specified torque limits.
• Avoid overloading the vehicle beyond the spring’s rated capacity to prevent premature fatigue.

Frequently Asked Questions

What is the difference between the RA1896 and other KYB coil springs?

The RA1896 features a higher spring rate and a more compact profile, making it suitable for vehicles that require both stiffness and limited suspension travel.

Can I use the RA1896 in a rear‑axle setup?

No. The RA1896 is specifically engineered for front‑axle mounting geometry and load distribution.

Is the spring compatible with aftermarket shock absorbers?

Yes, as long as the mounting interfaces match. It pairs well with KYB’s own K-Flex shock absorber line but can also work with other brands that share standard dimensions.

How long does the RA1896 last under normal driving conditions?

Typical service life exceeds 10,000 miles, depending on road quality and load variations.

Conclusion

The KYB RA1896 Coil Spring stands out as a reliable, high‑performance suspension component that delivers consistent ride quality, handling precision, and durability. Its engineered design ensures compatibility with a broad range of front‑axle vehicles while maintaining ease of installation for technicians. Whether upgrading an existing setup or building a new suspension system, the RA1896 offers a proven solution for drivers who demand both comfort and performance.
