Product Information
Full details
The KYB K-Flex RA1279 coil spring is designed for automotive technicians and DIY enthusiasts performing suspension repairs on Mercedes-Benz C-Class (W205) vehicles. Engineered to match strict OEM specifications, this component restores original ride stability and handling characteristics to your front axle. While it provides a high-quality, durable alternative to factory parts, it is essential to verify specific vehicle fitment and VIN compatibility before purchase, as suspension configurations can vary widely even within the same model series.

FAQs
Should I replace coil springs in pairs?
Yes, it is highly recommended to replace front coil springs in pairs to ensure even spring rates and consistent vehicle height on both sides of the axle.
Do I need a spring compressor for this installation?
Yes, a professional-grade coil spring compressor is mandatory to safely remove and install the spring from the strut assembly.
Is an alignment necessary after replacing these springs?
Absolutely. Changing suspension components alters the vehicle's geometry, and an alignment is required to prevent uneven tire wear and ensure safe handling.
How do I know if my old springs are worn out?
Common signs include a noticeable drop in ride height, a 'bouncy' feeling over bumps, or visible cracks or excessive rust on the spring coils.
Does the RA1279 fit all W205 models?
It is designed for specific W205 applications using the referenced OEM part numbers. Always cross-reference your specific vehicle VIN with the part catalog to confirm fitment.
Troubleshooting
Vehicle sits lower on one side after installation
Ensure the spring is correctly seated in the bottom control arm pocket and that the spring orientation is correct according to the manufacturer markings.
Clicking or clunking noise from the front suspension
Verify that the upper strut mount is tightened to specification and that the spring is not making contact with the inner fender liner.

Setup, Compatibility & Care
Installation of the KYB K-Flex RA1279 requires a specialized wall-mounted or portable coil spring compressor. Because these springs are under high tension, attempting installation without the proper equipment poses a significant safety risk.

Care Instructions
- Inspect the spring for any signs of surface corrosion or coating chips during routine oil changes.

- Always have the vehicle's wheel alignment checked and adjusted by a professional after suspension components are replaced.
