Why ACDelco Silver for GMT800

• GM aftermarket brand — same manufacturer that supplied factory brakes on your truck when it was new
• Multi-alloy iron construction — application-specific vane geometry optimizes cooling for the GMT800 heat load
• Non-directional ground finish — reduces noise, vibration, harshness (NVH) vs no-name replacement rotors
• OEM-spec thickness — no thickness variation on install; no pedal pulsation from day one
• Right choice for stock daily-driver Silverado — if you want factory feel with OEM quality, this is the pick
• Consider drilled/slotted upgrade instead if you tow, off-road, or want the visual upgrade

Install Notes

• Order 2 rotors for a full front axle replacement — always replace in pairs
• Torque caliper bracket bolts to GMT800 service spec (typically 129 ft-lb bracket)

• 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
