Detailed Description

Bilstein 36-159543 is a front coil spring engineered for standard suspension applications on 1990-2002 Mercedes-Benz vehicles. It is compatible with 1994-2002 Mercedes-Benz SL500, front; 1994-1997 Mercedes-Benz SL320, front; 1990-1993 Mercedes-Benz 300SL, front; and 1990-1993 Mercedes-Benz 500SL, front. This spring is built to OE dimensions and spring characteristics so the suspension can return to the original ride height and handling balance expected from the factory.

The B3 OE Replacement line is aimed at restoring the suspension system rather than changing its behavior. For Mercedes-Benz SL500 and SL320 front spring replacement, or for 300SL and 500SL standard suspension service without self-leveling suspension, this part number 36-159543 provides a direct OE-style solution.

This part cross-references Lesjofors 4056853 for the same application.

What It Helps Fix

• Sagging front ride height
• Uneven stance from worn coil springs

Installation Notes and Tips

Install on the front suspension only and verify standard suspension configuration before ordering. This spring is listed for standard suspension only on SL500 and SL320 applications, and for standard suspension without self-leveling suspension on 300SL and 500SL applications. Always inspect related suspension components, including mounts and dampers, during spring replacement.
