Geo Carbon Drilled and Slotted Brake Kit | Sierra 2500 HD

Choose brakes around the work your HD truck actually does

If your Sierra or Silverado HD spends its time towing, hauling, or running larger tires, a brake refresh deserves more thought than choosing a rotor pattern. This R1 Concepts kit pairs four Geo-Carbon drilled-and-slotted rotors with eight PERFORMANCE Off-Road/Tow brake pads and hardware for the listed front-and-rear applications.

Your factory brakes are the baseline for fitment, but this package changes the rotor surface design and uses a pad series aimed at off-road driving and heavy towing. Picture preparing the truck for a loaded weekend away: the useful upgrade is a complete rotor-and-pad package chosen for that duty, not a promise that a set of drilled holes will transform every stop. Confirm the exact brake configuration before ordering.

Who this is for

• Owners of compatible 2011–2019 GMC Sierra HD and Chevrolet Silverado HD applications who want front and rear rotors and pads.
• Trucks used for daily driving, heavy towing/hauling, off-roading, or overlanding, subject to confirmation of application and duty-cycle suitability.
• Lifted builds with larger tires/wheels whose brake configuration and wheel clearance have been checked.
• Buyers specifically looking for drilled-and-slotted rotors paired with R1 PERFORMANCE Off-Road/Tow pads.

Who this is not for

• Buyers wanting blank rotors or the separate R1 CERAMIC or OPTIMUM OEp pad packages.
• Anyone expecting larger calipers or a verified increase in towing capacity. This package lists rotors, pads, and hardware.
• Trucks ordered by year and HD badge alone, without checking actual rotor dimensions, drivetrain, and wheel clearance.
• Buyers treating the rotor-series mention of track racing as a dedicated competition rating for the complete kit.

What the components are designed to do

• Duty-focused pads: R1 PERFORMANCE Off-Road/Tow pads are specifically designed for off-road driving and heavy towing, including modified trucks and SUVs.
• High-friction formulation: The pad formulation is designed to provide smoother, more predictable responses at high temperatures.
• Drilled-and-slotted rotor faces: Geo-Carbon rotors feature diamond slots intended to help heat escape, with rotor-wear indications described in the supplied information.
• Countersunk drilled holes: Designed to help reduce cracking risk and support smoother pad break-in. This is not a guarantee against cracking.
• Corrosion-protective finish: A special coating is designed to help protect the rotors from corrosion and support appearance and service life.
• Included hardware: R1 hardware is intended to reduce noise and vibration and help prevent premature pad wear.
• Four-corner service package: Four rotors and eight pads cover the listed front and rear positions together.

Verify the rotor size, not just the wheel size

The source specifications label the kit option as 4WD, while its application table lists both 2WD and 4WD. That table also gives broad rotor-size ranges rather than the exact dimensions of the rotors supplied in this specific kit. Confirm part WBVH2-48019 against your truck’s actual brake configuration before ordering. Do not treat those ranges as an adjustable rotor size or proof that every brake package within them fits.

The listed wheel requirement is 18 inches or larger. Diameter alone does not establish clearance for every wheel design, so confirm your particular wheel and brake combination. Follow the manufacturer’s installation and bedding instructions and inspect the rest of the brake system during the service.

The supplied rotor-series information also names everyday street driving, track racing, off-roading, and towing/hauling. Choose the complete kit by its Off-Road/Tow pad specification and your actual use, rather than relying on a general rotor-series description.

Source application table: confirm before purchase

The following preserves the listed vehicle and dimension information. Exact supplied rotor dimensions and drivetrain compatibility require confirmation for this part number.

Fitment checkpoint: Verify part WBVH2-48019, drivetrain, actual front and rear rotor dimensions, and wheel clearance before ordering or disassembling the truck. A drilled-and-slotted pattern is not a substitute for correct application matching.
