Upgrade the rear braking performance of your GM 1500 with the Baer Brakes Big Claw Performance Rear Rotor Kit, Part Number BAE2302023. Designed for 1999-2018 GM 1500 two-wheel-drive and four-wheel-drive trucks, along with 2007-2018 GM 1500 two-wheel-drive, four-wheel-drive, and all-wheel-drive SUVs, this direct bolt-on system increases brake torque and leverage by using larger-than-stock rotors. The kit is engineered to improve stopping performance, reduce brake fade, and maintain compatibility with original-equipment brake pads and hardware.
The Big Claw kit includes a pair of purpose-cast rotors with directional cooling vanes and new OE-style caliper relocation brackets. The brackets move the factory calipers outward to accommodate the larger rotors without requiring replacement pads or hardware. Independent third-party testing reported up to a 49% improvement in braking effectiveness and rotor temperature reductions of as much as 200 degrees Fahrenheit compared with OE components under extreme conditions. Cross-drilled and slotted friction surfaces help release dust and gases, supporting consistent pedal feel during demanding driving.
A brilliant zinc-plated finish helps resist rust and corrosion while providing a clean appearance behind open-spoke wheels. Installation uses a simple, direct bolt-on design and does not require brake bleeding. Because wheel designs and clearances vary, Baer Brakes cannot guarantee fitment with every wheel. Use the application-specific template to verify clearance with your selected wheels, including the spare tire and wheel, before installation. Professional installation is recommended, and all components should be inspected for proper clearance and operation before driving.
