FAQs

What vehicles is the KYB RA3543 coil spring compatible with?

This coil spring is designed for the front axle of SEAT EXEO models manufactured between December 2008 and May 2013, specifically those with 2.0 TDI engines (143 BHP, 170 BHP, or 120 BHP) and without sports suspension.

What is the OEM part number this KYB spring replaces?

The KYB RA3543 coil spring is a direct replacement for the OEM part number 8E0411105DJ.

Do I need to replace both front springs?

While not strictly mandatory, it is highly recommended to replace coil springs in pairs (left and right) to maintain balanced suspension performance, handling, and ride height on both sides of the vehicle.

Can this spring be used on a SEAT EXEO with sports suspension?

No, this specific coil spring (RA3543) is designed for vehicles *without* factory sports suspension. Using it on a sports suspension model will alter the intended ride height and handling.

How long does it take for a new coil spring to 'settle'?

After installation, coil springs typically settle within a few hundred miles of driving. This settling period allows the spring to fully compress and find its resting position, potentially lowering the vehicle height slightly to its final operating level.

Where can I find installation instructions?

Installation instructions are not typically provided with the part itself. Due to the safety-critical nature and specialized tools required, coil spring replacement should be carried out by a professional mechanic who has access to the necessary service manuals and equipment.

What are the cross-reference part numbers?

The KYB RA3543 coil spring cross-references include KILEN 23540 and LESJÖFORS 4082940.

Troubleshooting

Vehicle sits too low after installation.

Ensure the correct spring was installed for the vehicle's specifications. Verify that the spring is fully seated in its perches. Check if other suspension components (e.g., worn bushings, damaged control arms) are contributing to the low ride height. It is also possible the spring needs time to settle fully.

Clunking or rattling noises from the front suspension.

Verify that the spring is correctly seated and that all associated hardware (e.g., spring isolators, mounting bolts) is securely tightened. Check the condition of the shock absorber and its mounts, as well as other suspension components like sway bar links and bushings.

Vehicle pulls to one side.

This issue is typically related to wheel alignment rather than the coil spring itself. However, ensure the springs were installed correctly and that the vehicle's weight is evenly distributed. Have a professional perform a wheel alignment check.

Setup, Compatibility & Care

Compatibility Verification:

Before purchasing, it is essential to verify fitment using the vehicle's make, model, and year information, paying close attention to engine type (2.0 TDI with specific BHP) and the absence of sports suspension. Cross-reference with the OEM part number 8E0411105DJ or other listed cross-references (KILEN 23540, LESJÖFORS 4082940) if possible. If unsure, contact customer support with your vehicle's VIN.

Installation:

Installation of coil springs should always be performed by a qualified mechanic. This process involves safely jacking up the vehicle, removing the wheel, and carefully disassembling the suspension components. Specialized tools, such as spring compressors, are required to safely remove and install the coil springs. It is often recommended to replace coil springs in pairs (left and right) to ensure even weight distribution and consistent handling.

Care:

Coil springs are a passive suspension component and require no regular maintenance. However, it's good practice to have suspension components inspected during routine vehicle check-ups. Look for signs of rust, corrosion, or physical damage to the spring, which could compromise its integrity. Ensure surrounding suspension components like shock absorbers and bushings are in good condition to maximize the lifespan and performance of the coil springs.
