Vehicle Fitment

• 2012–2018 Jeep Grand Cherokee SRT / SRT8 (6.4L HEMI V8, 4WD) — with Brake Code BR4, 350mm rear rotor

Fitment Notes

• Fits only Jeep Grand Cherokee SRT and SRT8 models equipped with the factory BR4 brake package (350mm rear rotor). Standard Laredo, Limited, Overland, and Summit trims with smaller rear rotors require a different kit.
• Does NOT fit the 2018 Jeep Grand Cherokee Trackhawk — the Trackhawk uses the same 350mm rear rotor size but has a different rear caliper design; verify caliper compatibility before ordering.
• This is a rear axle kit only. Sold as a complete set for one vehicle (2 rotors + 1 set of brake pads).
• All Grand Cherokee SRT/SRT8 models are 4WD only.

Features

• Complete rear brake solution in one box — Prime UV-coated PVT vented rotors and Prime Ceramic pads are matched by Brembo specifically for the SRT brake package.
• Brembo's patented Pillar Venting Technology (PVT) increases airflow through the rotor for up to 40% greater resistance to thermal cracking — essential under the high-performance demands of the 6.4L HEMI V8.
• Full UV coating across the entire disc surface delivers immediate corrosion protection; rotors are ready to install out of the box with no prep required.
• Prime Ceramic pad compound provides quieter operation, significantly reduced brake dust, better heat dissipation, and longer pad life compared to semi-metallic alternatives.
• High-carbon cast iron rotor construction minimizes NVH (noise, vibration, harshness) for smooth, controlled stopping under both daily driving and spirited use.
• All required fixing hardware included — direct bolt-on replacement for the factory SRT rear brake setup.

Product Description

The Brembo KT00643 is a complete rear brake kit engineered specifically for the 2012–2018 Jeep Grand Cherokee SRT and SRT8, equipped with the factory BR4 brake package. It pairs Brembo's Prime UV-coated 350mm PVT vented rear rotors with their Prime Ceramic NAO brake pads — both matched by Brembo to the SRT's high-performance braking requirements. The rotors feature Brembo's patented Pillar Venting Technology (PVT), which dramatically improves internal airflow and thermal management, a critical benefit on a vehicle driven by a 470+ horsepower 6.4L HEMI V8 that places demanding loads on the rear braking system.

Everything needed to restore the complete rear axle is included in one box — rotors arrive UV-coated and installation-ready, while the ceramic pads deliver cleaner wheels, quieter stops, and superior pad longevity over factory semi-metallic alternatives. This kit is application-specific to the SRT/SRT8 brake package; owners should confirm their Grand Cherokee carries the BR4 brake code before ordering to ensure correct fitment.
