Durable Construction and Precise Fitment

The DuraGo BR901582 rotor is constructed from full cast iron, providing a solid and reliable braking surface. Its vented design helps reduce heat buildup during braking, which can minimize rotor warping and extend service life. This rotor is designed as a conventional, non-directional type, making installation straightforward without the need to align directional vanes. The absence of cross-drilled or slotted features means it maintains a smooth braking surface, suitable for standard driving conditions. With precise dimensions including a 2.64 inch (67 mm) center hole diameter and 0.6 inch (15.3 mm) mounting bolt hole diameter, this rotor ensures a secure fit on compatible Mercedes-Benz GL and GLS models.
