Overview
The Baer Big Claw rear rotor kit, part number 2142011, is built for 2019–2025 Ram 1500 trucks with the new body style, in 2WD or 4WD. The rotors are larger than stock in diameter, up to 2 inches on some applications, and use curved directional vanes in a one-piece full cast body.
Relocation brackets shift the calipers outward so the larger rotors have room, and the OE pads and hardware still fit. Independent third-party testing shows up to a 49 percent gain in braking effectiveness from the larger diameter, and as much as a 200-degree reduction in rotor temperature versus OE in extreme conditions. The kit uses a 6×139.7mm bolt circle, so match that against your truck before ordering.
Key features
- Oversized one-piece rotors that increase brake torque and leverage at the rear
- Cross-drilled and slotted friction surface that clears dust and gases for steady braking
- Curved directional vanes that move air through the rotor and limit brake fade
- Relocation brackets make room for the larger rotors and keep OE pad and hardware use
- Simple bolt-on installation, no brake bleeding required
- Zinc plated finish resists rust and corrosion behind open-spoke wheels
Choosing a rear kit
A rear rotor kit with relocation brackets changes the caliper position, so the setup should be judged as a whole. Confirm the bolt circle and axle type first, then check the rotor hat fit, the bracket hardware and the wheel clearance. Because the calipers move outward, the brake lines and caliper bolts should be checked for free movement before the wheel goes back on.
Rear rotors on a light-duty pickup are often replaced in pairs, and the pads are usually inspected at the same time. Look for uneven wear, heat cracks near the vent slots and any pulsing in the pedal. Keep the wheel and hub surfaces clean, and recheck the caliper bolts after the first few drives.
- Confirm the bolt circle and axle type before buying
- Check brake line movement after the calipers are relocated
- Inspect pads at the same time as the rotors
- Recheck caliper bolts after the first few drives

Vehicle fitment
The kit is a rear-axle part for the 2019–2025 Ram 1500 with RWD or 4WD drive, Performance Upgrade units and a 6×139.7mm bolt circle. Ram 2500 and 3500 trucks use a different rear kit.
Ram 2500 and 3500 trucks are covered by Baer’s HD rear kit, part 2142013-2, not this one. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The swap is rear-axle bolt-on work with no brake bleeding required. Use Baer’s template for this system and compare it to your wheel, spare included, because the company cannot guarantee fit into every wheel. After the brackets are installed, recheck caliper clearance to the wheel.
What’s included
Two rear rotors come with two brackets that move the calipers outward.
