Description
Better Thermal Management & Braking Consistency. These rotors feature precision-machined directional slots that evacuate brake dust, hot gases, and moisture from the pad interface. This ventilation preserves pad contact and significantly reduces fade during repeated stops or high-load conditions.
Long-Term Rust Resistance. Finished with SP’s proprietary Gray ZRC zinc-rich coating, the rotors resist corrosion even in aggressive environments. The protective layer remains intact through heat cycling and preserves a clean finish behind wheels without flaking or peeling.
Reliable Braking in Wet, Dry, and Heavy-Duty Use. The slotted design actively clears water, pad residue, and road debris, improving brake bite while resisting fade. Ideal for trailer towing, heavy payloads, or dusty and wet operating conditions, these rotors maintain consistent performance.
Installation. Putting these SP Performance Slotted 8-Lug Rotors with Gray ZRC Coating; Front Pair on your Sierra 2500 HD takes 2 hours to install.
Application. The SP Performance Slotted 8-Lug Rotors with Gray ZRC Coating; Front Pair fit 2011-2026 Sierra 2500 HD models.
