PowerStop JBR1737XPR Disc Brake Rotor Set - Rear

Drilled and Slotted Rear Rotor Upgrade

PowerStop JBR1737XPR is a drilled and slotted rear disc brake rotor set built for direct OE fitment on select Lexus, Toyota, and related applications. The vented rotor design, zinc dichromate coating, and precision-machined surface help support consistent braking performance while resisting rust and corrosion.

For drivers searching for a rear brake rotor upgrade for Lexus RX350, Lexus RX450h, or Toyota Mirai, this Power Stop rotor pair offers a straightforward replacement with performance-focused surface design and OE-style fit.

Product Details

Power Stop’s drilled, slotted, and zinc plated brake rotor line is focused on OE-style replacement with added thermal and surface-management features. JBR1737XPR uses cross-drilled holes to improve airflow through the rotor and rounded slots to help clear debris and moisture from the braking surface. That combination supports stable pedal feel and consistent contact under demanding stop-and-go or downhill driving conditions.

This part cross-references Centric Parts 120.44197 and Raybestos Brakes 982051 for the same application. It is a strong match for rear brake service on Lexus RX350, Lexus RX450h, and Toyota Mirai applications where a drilled and slotted rear rotor is specified.

What It Helps Address

• Brake fade from heat buildup during repeated stops
• Surface rust on exposed rotor faces
• Dust and moisture buildup on the braking surface
• Uneven rotor appearance from corrosion exposure
• OE rotor replacement needs on rear brake service
