Why Drilled and Slotted for GMT800

• Better heat shedding — the GMT800 front brake is undersized for the truck's weight when loaded; drilled/slotted face lets gases and water escape faster
• E-coating on hat and edges — the rotor cosmetic edges stay rust-free through daily driving and winter salt
• Bolt-on replacement — no modification required, works with factory calipers
• Right choice for tow or off-road use — if the truck sees mountain grades, hauling, or off-road duty, drilled/slotted rotors handle the heat better than plain-face
• For pure daily driving — plain-face rotors work fine and cost less; drilled/slotted is upgrade territory

Install Notes

• Torque caliper bracket bolts per GM GMT800 service spec (typically 129 ft-lb bracket)
• Silicone caliper grease on slider pins — not chassis grease
• Bed pads with matching new rotors: 8-10 medium stops from 40 to 10 mph, then 2-3 harder stops from 60 to 15 mph, air-cool between
• Measure old rotor before removing to confirm 11.99 inch (304.6 mm) diameter
• Consider matching new pads — old pads on new rotors transfer material unevenly
