This coil spring delivers superior ride quality, improved handling, and enhanced durability compared to many aftermarket alternatives.

Key Technical Specifications

• Model Number: RH3286 (also referenced as 51401SMJE01/02/04 in OEM catalogs)
• Application: Front axle, left and right sides
• Spring Type: K‑Flex Helical Coil
• Material: Premium alloy steel with advanced heat treatment for high fatigue resistance
• Load Capacity: Designed to support the weight of a fully loaded Civic 2.2D, ensuring consistent performance under varying road conditions
• Dimensions: Matches OEM specifications exactly, guaranteeing a seamless fit without modification

Design Features and Benefits

The K‑Flex technology incorporated in the RH3286 provides a balanced combination of stiffness and compliance. This results in:

• Improved Road Holding: The spring’s precise tension curve enhances tire contact with the road, especially during cornering.
• Reduced Body Roll: By maintaining optimal suspension geometry, the RH3286 minimizes body lean on turns.
• Enhanced Comfort: The controlled rebound characteristics absorb bumps more effectively than standard springs.
• Long‑Term Reliability: Heat‑treated steel resists corrosion and fatigue, extending service life even under aggressive driving.

Installation and Compatibility

The KYB RH3286 Coil Spring is engineered for a plug‑and‑play installation. It matches the OEM mounting points and spring seat dimensions of the Honda Civic 2.2D front axle, eliminating the need for additional hardware or modifications.

1. Remove Existing Springs: Detach the current coil springs from both left and right sides.
2. Mount RH3286: Secure each new spring into its designated seat, ensuring proper alignment.
3. Reinstall Suspension Components: Reattach shocks, struts, and any associated hardware.
4. Torque Specifications: Follow OEM torque values for all fasteners to guarantee safety and performance.

Performance Comparison

When compared with generic aftermarket springs, the KYB RH3286 offers:

Applications Beyond Honda Civic

While the RH3286 is optimized for the Civic 2.2D, its design allows it to be used in other vehicles that share similar suspension geometry and spring dimensions, such as certain Honda Accord models or Honda Fit variants. Always verify compatibility with OEM specifications before installation.

Maintenance Tips

• Regular Inspection: Check for signs of wear, corrosion, or deformation every 10,000 miles.
• Shock Absorber Coordination: Pair the RH3286 with compatible shocks to maintain balanced suspension dynamics.
• Proper Torque: Re‑torque all mounting bolts after initial installation and during routine maintenance.
