FAQs

Should I replace these in pairs?

Yes, it is highly recommended to replace front coil springs in pairs to ensure even suspension height and consistent handling performance.

What tools do I need for installation?

You will need a professional-grade coil spring compressor, a set of metric sockets, and a torque wrench.

Is an alignment necessary after replacing springs?

Yes, changing suspension components alters the vehicle's geometry, and an alignment is required to prevent uneven tire wear.

How do I know if this fits my car?

Compare your current strut's OEM part number with the references 546302Y300, 546302Y301, or 546302Y304.

Does this include the struts or mounts?

No, the KYB RA3463 is the coil spring only; struts and upper mounts are sold separately.

Troubleshooting

Vehicle still sits uneven after installation

Verify that the spring is seated correctly in the lower control arm and upper mount. Ensure the opposite side was also inspected for wear.

Noise during steering or over bumps

Check that the top mount bearing and all mounting bolts were tightened to the manufacturer's specified torque values.

Pros and Cons

Pros

  • Matches original equipment ride height and comfort
  • High-quality steel construction for long-term durability
  • Direct fit for simplified installation on compatible Hyundai and Kia vehicles
  • Reduces strain on related front-end suspension components

Cons

  • Requires professional spring compressor tools for safe installation
  • Recommended to be replaced in pairs, increasing the total parts cost
  • Verification of OEM cross-reference numbers is mandatory to prevent fitment issues

Setup, Compatibility & Care

Before installation, verify that your vehicle matches the OEM part references: 546302Y300, 546302Y301, or 546302Y304. Installation requires a high-quality strut spring compressor tool; because of the high tension stored in compressed springs, it is highly recommended to perform this task in a workshop environment with proper safety equipment. Post-installation, a professional four-wheel alignment is necessary to ensure proper tire wear and vehicle safety. To prolong the life of your new springs, ensure that all mounting hardware and dust covers are inspected for damage during the swap.
