Overview
The Baer Brakes 53039-020 is a set of rear Claw performance rotors for the 2006-2010 Jeep Grand Cherokee SRT8 (WK). Sold as a pair, these one-piece, full cast iron vented rotors are direct replacements for the factory rear discs. Baer positions them for drivers who want a cross-drilled and slotted braking surface along with a zinc-plated look behind open center wheels.
The slotted and drilled face gives gases and dust a path out from between the pad and rotor, which supports a steadier pedal feel and less brake fade during repeated stops. The vane structure is designed to improve cooling, and the chamfered drilled holes are intended to limit stress cracking around the openings.
Key features
- Cross-drilled and slotted friction surface that lets gases and dust escape between pad and rotor
- Vane structure designed for better cooling and durability
- Premium, mill balanced direct replacement rotor
- Chamfered cross drilled holes to minimize stress cracking
- Zinc-plated finish for a bright look behind open center wheels
- Directional brake surface
Before you buy
Rear rotors wear more slowly than fronts on many trucks and SUVs, but they still need periodic checks. Look for a raised lip at the outer edge, deep grooves, blue discoloration, or pulsing through the pedal under light braking. Any of these signs suggests the rotor should be measured against its minimum thickness before reuse.
Cross-drilled and slotted faces trade some pad life for better gas and dust release, so pad choice matters. Softer compounds can wear faster on a drilled face, while harder compounds may need longer bedding. Choose pads designed for performance use so the rotor and pad work together.
- Replace pads and rotors as a matched pair on each axle
- Clean rust from the hub before mounting
- Check lug nut torque after the first few drives
- Inspect caliper slide pins while the rotors are off

Vehicle fitment
These rotors are a direct fit for the 2006-2010 Jeep Grand Cherokee (WK) SRT8 and fit the rear axle only.
Fitment is for the SRT8 trim only. Confirm fit for your vehicle’s year, model and trim before ordering.
Installation notes
Clean the hub mating surface and check it for rust or ridges before fitting. Because the face is cross-drilled and slotted, bed in new pads gradually before heavy use. Support the vehicle on jack stands only, never on a jack alone.
What’s included
A pair of rear one-piece rotors, sold as a set.
Not included: brake pads and hardware.
