Product Details

The Keystone BM1550121 is an OEM-replacement rear left power window regulator designed for BMW 3-Series Sedan and Wagon applications. This direct-fit replacement restores proper window operation and is engineered to match the original equipment specifications of the factory regulator.

Key Features:

  • OEM Replacement: Cross-references to BMW OEM part number 51357281887 for confident fitment
  • Power Operation: Designed for power window systems — no manual conversion required
  • Motor Not Included: Regulator only — retains and reuses your existing window motor
  • Left-Hand (Driver Side) Rear Position: Engineered specifically for the rear left door installation
  • Direct-Fit Design: Bolt-on replacement requiring no modifications for proper installation
  • Sedan and Wagon Compatible: Fits 3-Series Sedan (2012–2018) and Wagon/Sports Wagon (2014–2019)

Manufactured by Keystone Automotive Industries, a trusted name in collision repair and OEM-style replacement parts, this window regulator meets the quality standards expected for professional and DIY installations alike. Cross-reference OEM part number: 51357281887.
