LH DDS Rotor 1.25in x 11.75in Non-Slotted

The PFC BRAKES LH DDS Rotor 1.25in x 11.75in Non-Slotted (SKU: PFR299.32.0045.11) is a left-hand driver-side brake rotor engineered for late-model and Cascadia heavy-duty commercial vehicles. This 299mm OD plain steel rotor delivers consistent thermal dissipation and reliable braking performance in high-mileage fleet and vocational applications where durability and fade resistance are critical operational requirements.

Specification-wise, the rotor measures 299mm in outside diameter with a 32mm thickness, designed to work with an 8 x 7.000-inch bolt pattern typical of Class 7–8 truck platforms. The non-slotted design provides a larger effective friction surface compared to vented configurations, maximizing brake pad contact area for sustained stopping power under continuous braking cycles. Steel construction rated for natural finish delivers straightforward corrosion protection suited to highway and regional haul duty. At 13.99 pounds per rotor, this component carries the mass needed to absorb and dissipate heat generated during repeated brake events without excessive fade.

Fleet maintenance operations, owner-operators managing long-haul schedules, and commercial service centers rely on PFC brake components to maintain vehicle safety and compliance with DOT braking standards. This left-hand rotor replaces OEM equipment on qualifying Cascadia and late-model heavy trucks, ensuring proper axle symmetry and balanced brake force distribution. The plain non-slotted profile is well-suited to paired air-spring brake systems where thermal management takes priority over aggressive modulation performance.
