Performance + Heavy-Duty Brakes for 2011-2019 Chevy/GMC 2500HD/3500HD 6.6L Duramax

LML & L5P Duramax Brake Kits: 2011–2019 Chevy/GMC 2500HD & 3500HD

The Highest-Performing Brake Kits for the Best-Selling HD Duramax Platform

The LML (2011–2016) and L5P (2017–2019) Duramax trucks represent the most capable and most refined GM HD diesel platform ever built. Owners of these trucks tend to run them hard, with long-haul towing, fifth-wheel setups, and serious payload work, and they invest in their trucks accordingly. Our LML and L5P brake kits are the top of the catalog. If you're looking for a complete front and rear performance brake system, upgraded drilled and slotted rotors, high-temp compound pads, and all necessary hardware — this is it.

What a Complete Brake System Upgrade Gets You

The gap between a full brake kit and an OEM pad replacement is significant at this performance tier. Compound-specific pads rated for sustained heavy-duty stops, paired with drilled and slotted rotors that manage heat more effectively than OEM blanks, translate directly into shorter stopping distances under load, reduced fade on grade, and longer service intervals between brake jobs. For a truck that's doing serious towing work, that's not an upgrade; it's the setup the truck should have come with.

Flexible Payment Available

Our LML and L5P brake kits qualify for financing through Affirm, so you can get the complete setup now and pay over time. Complete kits represent the best value per stop — and splitting the cost across payments makes it easier to do the full job at once rather than phasing in components.

Silverado and Sierra, 2500HD and 3500HD

Brake fitment is consistent across the Silverado and Sierra nameplates within each model year, but varies by year, cab configuration, and rear axle setup (SRW vs. DRW on the 3500HD). Our catalog is sorted by vehicle so you land on the right kit.
