Genuine BMW Rear Window Sealing Gasket With Lower Trim - E90

Product Details

Degraded glass seals aren't just an eyesore. Hardened rubber allows water retention and wind turbulence that can degrade your chassis over time. Whether you’re restoring an everyday E90 328i or keeping an E90 M3 in top tier shape, fresh factory seals are vital for preserving aesthetics and keeping the cabin quiet.

This Genuine BMW Rear Glass Seal & Refresh Kit restores proper sealing performance along the entire rear window margin. Made to exact BMW OE specs, these components match the precise curvature and material density required for a tight, factory weather barrier.

Kit Contents:

• Rear Window Perimeter Sealing Gasket

• Lower Rear Window Trim / Cover

Benefits & Fitment Notes:

• Guaranteed exact fitment without binding, trimming, or gap issues.
