Front Spring Pad

The BMW Genuine Parts 31331091864 is a direct-fit spring pad designed for the front lower suspension of various BMW models. As a genuine BMW part, it is manufactured to the same stringent standards as the original equipment installed at the factory, ensuring quality and compatibility. This spring pad plays a vital role in the front suspension system, working in conjunction with coil springs to support the vehicle's weight and maintain optimal ride height and handling characteristics. It is recommended that coil springs and their associated hardware, including spring pads, are always replaced in pairs to ensure balanced suspension performance. This part is compatible with a range of BMW E39 and E46 chassis vehicles, including specific models such as the 323i, 328i, 528i, 540i, and M5. Fitment details include specific model years, engine sizes (2.5L, 2.8L, 4.4L, 5.0L), drivetrain configurations (RWD Sedan/Wagon), and transmission types (Automatic/Manual). Some listings note fitment up to specific production dates, such as 'Thru 08/1999' or 'Thru 09/1999', and some models may have specific notes regarding Electronic Damper Control (EDC). It is recommended to verify exact fitment using your BMW's VIN. Symptoms of failing coil spring insulators or springs include loss of spring rate, potential for breaking or cracking, sagging or uneven ride height, unusual noises over bumps (clunks, clanks), and a rougher ride with poor handling or a lack of suspension support. Replacing worn components like this spring pad is essential for restoring proper suspension function and ensuring safe vehicle operation.
