Key Features

DBA’s 4000 Series Plain Rear Rotor incorporates cutting-edge technology and design elements to maximize braking efficiency and rotor lifespan:

• Constructed from XG-150 high carbon alloyed iron for superior strength and thermal stability
• Thermal Stability Profiling (TSP) enhances heat resistance and reduces the risk of warping
• Patented Kangaroo Paw ventilation design improves cooling efficiency by 20% over traditional rotors
• Increased surface area by 30% for better heat dissipation and consistent braking performance
• Plain, smooth OE-style finish maintains a factory appearance suitable for controlled race divisions
• Direct replacement fitment ensures hassle-free installation without modifications
• Moisture-proof corrosion protection extends rotor life and maintains performance in harsh conditions

Construction & Design

The rotor is crafted from DBA’s proprietary XG-150 high carbon alloyed iron, a material known for its exceptional durability and ability to withstand high temperatures generated during braking. This alloy, combined with Thermal Stability Profiling, minimizes thermal cracking and distortion, ensuring the rotor maintains its structural integrity over time.

DBA’s patented Kangaroo Paw ventilation system features uniquely shaped vents that increase airflow through the rotor, significantly improving cooling efficiency. This design not only reduces brake fade during aggressive driving but also prolongs the life of brake pads and other components by maintaining optimal operating temperatures.

The smooth, plain surface finish offers a clean, OEM look while providing consistent pad contact and braking feel. Additionally, the rotor is treated with a moisture-proof coating to resist rust and corrosion, making it ideal for varied weather conditions and long-term use.

Installation & Fitment

This rear rotor is a direct replacement for the 2005–2010 Jeep Grand Cherokee, designed to fit perfectly with factory brake components. Installation requires no modifications, allowing for a straightforward swap with your existing rotors. The rotor’s precise manufacturing tolerances ensure proper alignment and fitment, maintaining the integrity of your vehicle’s braking system.

For best results, it is recommended to replace rotors in pairs and inspect brake pads and hardware during installation to ensure optimal braking performance and safety.
