You should use the make and model tool provided on the product page. If you are still unsure, it is best to contact customer support with your vehicle details to confirm fitment.
Do I need to replace both front springs?
For optimal and balanced handling, it is generally recommended to replace coil springs in pairs (both front or both rear) to ensure consistent performance across the axle.
Troubleshooting
Vehicle sits lower at the front than before
Ensure the coil spring is correctly seated in its perches and that all suspension components are properly reassembled and torqued. A worn-out shock absorber on the same side could also contribute to ride height issues.
Unusual noises from the front suspension
Check that the coil spring is properly seated and that no foreign objects are interfering with its movement. Also, inspect rubber isolators or mounts for wear or damage. Noises could also indicate issues with other suspension parts like bushings or ball joints.
Poor handling or excessive body roll
Verify the spring is the correct part for your vehicle's suspension type (standard, not sports). Ensure correct installation and that other suspension components (shocks, bushings) are in good condition.

Setup, Compatibility & Care Instructions
Compatibility Check:
Before installation, verify that your vehicle is a MERCEDES-BENZ SLK (R171) 200 Kompressor manufactured between March 2004 and February 2011. Crucially, confirm that your vehicle is equipped with standard suspension and *not* sports suspension. Always use the vehicle make and model tool or consult a professional if unsure. Cross-reference part numbers with OEM MERCEDES-BENZ 1713210404, A1713210404, or SUPLEX 19350.
Installation:
Installation of coil springs is a complex task that requires specialized tools and automotive knowledge. It is strongly recommended to have the KYB RH3303 coil spring installed by a qualified mechanic. The process typically involves safely lifting the vehicle, removing the wheel, and carefully unbolting suspension components to access and replace the spring. Ensure all fasteners are torqued to manufacturer specifications after installation.
Care:
Coil springs are designed for durability and require minimal direct care. However, it is good practice to periodically inspect your suspension system for any visible signs of damage, corrosion, or leaks from associated components like shock absorbers. Keeping the undercarriage clean can help prevent premature corrosion of the spring's protective coating.
