Whiteline Plus 4/91-5/01 & 10/01-05 BMW 3 Series/9/88-04 5 Series Rear 20mm Sway Bar Mount Bushing

If you're working on the suspension of a BMW 3 Series or 5 Series from the early 90s through the mid-2000s, Whiteline's 20mm rear sway bar mount bushings are a common and worthwhile service item. These bushings are what hold your rear sway bar in place, and over time, the original rubber can wear out, leading to increased body roll and less precise handling. Replacing them is a straightforward way to restore that solid, connected feel to your car's cornering.

Whiteline uses a synthetic elastomer formulation that's built to resist common shop fluids like oil and grease, as well as ozone and general weathering. Inside the bushing, you'll find grease retention lips and internal knurling designed to keep the included molybdenum disulfide-based grease where it needs to be, ensuring continuous lubrication and friction management. This means they'll keep working well for a long time, helping to keep your sway bar moving smoothly within its mounts.

When you're ready to replace these, make sure to measure your existing sway bar diameter to confirm you're getting the correct 20mm size. This kit is designed to fit a wide range of BMW models, including popular ones like the E36 3 Series, E46 3 Series, and E39 5 Series.
