Keystone BM1351135 Front Right Power Window Regulator Without Motor

The Keystone BM1351135 is an OEM-replacement front right (passenger side) power window regulator designed for the BMW X5 (F15/F85 chassis, 2014–2018). This regulator is sold without the motor, allowing for a targeted repair that reuses the existing window motor — an ideal solution when the regulator mechanism has failed but the motor remains functional.

The window regulator is the mechanical assembly mounted inside the door that converts motor torque into the up-and-down motion of the door glass. It uses a cable-driven track system running along metal rails to smoothly and reliably guide the window glass. Over time, cables can fray, plastic components can wear, and the assembly can bind — resulting in slow, noisy, or completely inoperative windows. This Keystone replacement restores proper window function to OEM specifications.

Key Features:

• OEM-style fit: Direct replacement for BMW OEM part number 51337286484 (51-33-7-286-484)
• Regulator only: Sold without motor — transfer your existing motor to the new assembly
• Position: Front right (passenger side)
• Power operation: Designed for vehicles equipped with factory power windows
• Keystone quality: Engineered to meet or exceed original equipment standards for fit and function
• Chassis: BMW X5 F15 / X5M F85 (2014–2018)

This part cross-references OEM BMW part number 51337286484. Installation requires transferring the factory window motor to the new regulator assembly. Always inspect window glass guides and door seals at the time of replacement, as worn seals increase friction and can accelerate future regulator wear.
