FAQs

How do I know if I need to replace my coil springs?

Signs include a visibly sagging front end, clunking noises over bumps, poor handling, or uneven tire wear. A professional inspection can confirm if your coil springs are worn or damaged.

Can I replace just one coil spring?

While technically possible, it is generally recommended to replace coil springs in pairs (left and right) on the same axle to ensure balanced handling and ride height. Replacing only one may lead to uneven suspension performance.

What is the warranty on this KYB coil spring?

Warranty information varies by retailer. Please check the specific warranty provided by the seller at the time of purchase.

Does this part come with installation instructions?

This product is a spare part and typically does not include installation instructions. Professional installation by a qualified mechanic is recommended.

What is the difference between OE/OEM numbers and the MPN?

The MPN (Manufacturer Part Number) is unique to the manufacturer (KYB in this case, RH3941). OE/OEM numbers are original part numbers from the vehicle manufacturer (e.g., Audi, VW, Skoda) that this KYB part is designed to replace.

How should I verify compatibility for my vehicle?

Use the OE/OEM reference numbers provided in the product description and cross-reference them with your vehicle's service manual or consult with a parts specialist or mechanic.

Troubleshooting

Vehicle still sags after replacement

Ensure the correct spring was installed and that it is fully seated. Check if other suspension components (like shocks or control arms) are also worn and contributing to the sag.

Noise from the front suspension

Verify the spring is correctly installed and not rubbing against other components. Ensure any spring isolators or rubber seats are in place and in good condition.

Uneven ride height between sides

Confirm that the same part number was installed on both sides if replacing a pair. Check for other suspension issues that might cause unevenness, such as worn bushings or differing tire pressures.

Setup, Compatibility & Care

Compatibility: Vehicle compatibility for the KYB RH3941 should be verified using the provided OE/OEM reference numbers (e.g., SKO-1K0411105DB, AUD-8P0411105E, VWA-1K0 411 105 EB) against your vehicle's specifications. Always consult a professional mechanic or use a trusted vehicle fitment guide to ensure this part is correct for your specific make, model, and year. Note that multiple options might exist for some vehicles.

Setup: Installation of a coil spring requires specialized tools, including spring compressors, and should only be performed by a qualified mechanic. The spring fits in the front position. Proper tensioning and seating of the spring are critical for safety and performance.

Care: Coil springs are generally maintenance-free. However, it is advisable to have suspension components inspected periodically during routine vehicle maintenance. Keep the springs clean from excessive dirt and road salt, especially in winter climates, to prevent premature corrosion.
