Front Right Coil Spring (Separate) - 2011 528i

When sourcing BMW F10 chassis components from salvage yards, focus specifically on 2011-2012 528i sedans equipped with the naturally aspirated N52B30 inline-six. The front right coil spring carries BMW part number 31 33 6 792 376 for standard suspension, paired with 31 33 6 792 375 on the left side. These are weight-critical components—inspect for the painted color bands (typically white, yellow, or orange) indicating load class; mismatched springs cause uneven ride height. Common failures include corrosion at the bottom coil where road salt accumulates in the lower perch. During installation, use a professional spring compressor and always replace the upper spring pad (31 33 6 760 953) and thrust bearing to prevent noise. Avoid 2013+ model year donors, as BMW transitioned to the lighter N20 engine with incompatible spring rates. Verify the vehicle option sticker for S704A Sport suspension, which uses shorter, higher-rate springs.
