Overview
The Big Claw rear disc brake rotor kit, part number 2302024, is an oversized rear rotor set for 4WD and AWD GM 1500 vehicles from 2000 to 2006. It is covered for the 2000–2006 Chevrolet Silverado 1500 and also applies to several Cadillac, Chevrolet and GMC SUVs from the same years.
Big Claw rotors are cast with directional cooling vanes and can be up to 2 inches larger than stock on some applications. Two new caliper relocation brackets move the calipers outward to fit the bigger rotor, and the OE pads and hardware still fit. Independent third-party testing measured a braking effectiveness gain of as much as 49 percent for this design.
Key features
- Cross-drilled and slotted friction surface that Baer says helps vent dust and gases
- One-piece, full-cast rotor with curved vanes and a directional brake surface
- Zinc-plated, rust-resistant finish that suits open-spoke wheels
- Drum-in-hat, floating rear rotor design
- Caliper relocation brackets included for the larger diameter
- Lists 4WD and AWD applications with 6 lugs
Rust and corrosion on rear rotors
Zinc-plated rear rotors resist surface rust, but salt, road spray and mud still work into the hat and the mounting face over time. Light surface rust on the friction area usually clears with normal braking, while rust that builds on the hub face can throw the rotor out of true. Clean the mounting surfaces before every install so the rotor seats flat.
Cross-drilled and slotted rotors shed water and debris faster than plain rotors, which helps in wet conditions. The holes and slots also create edges that wear, so inspect them whenever the pads are changed. A rotor with cracks running from a hole toward the braking surface should be replaced.
- Clean the hub face and wheel studs before mounting
- Check the caliper brackets for correct seating
- Inspect the rotor edges at each pad change

Vehicle fitment
Covered vehicles are the 2000–2006 Chevrolet Silverado 1500 in the Hybrid, LS, LT, SS, WT and Z71 trims. Rear fit also covers the 2000–2006 Cadillac Escalade, Escalade ESV and Escalade EXT, Chevrolet Avalanche 1500, Suburban 1500 and Tahoe, and GMC Yukon and Yukon XL 1500, each with 6 lugs.
Model years after 2006 are not covered, and the listed drive types are 4WD and AWD only. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The two caliper relocation brackets are part of the rear swap, so have them ready before starting. The swap is a direct bolt-on that does not require bleeding the brakes. Check the system template against your wheel, including the spare, before installing.
What’s included
The kit includes a pair of rear Big Claw rotors and a pair of new caliper relocation brackets.
