Key Features

DBA’s 4000 Series Plain Front Rotor incorporates advanced technologies and design elements that set it apart from standard rotors:

• XG-150 High Carbon Alloyed Iron: Provides superior strength and thermal conductivity for enhanced durability and heat dissipation.
• Thermal Stability Profiling (TSP): Precision-machined to minimize thermal distortion and rotor warping during heavy braking.
• Kangaroo Paw Ventilation: Patented vent design increases surface area by up to 30%, improving cooling efficiency by 20% over traditional rotors.
• OE-Style Smooth Finish: Maintains a factory appearance while reducing brake dust and noise.
• Moisture-Proof Corrosion Protection: Extends rotor life by preventing rust and corrosion in various weather conditions.
• Direct Replacement Fitment: Designed for a perfect fit with no modifications required, ensuring easy installation.

Construction & Design

The DBA 4000 Series rotor is crafted from XG-150 high carbon alloyed iron, a material known for its excellent wear resistance and thermal properties. This composition allows the rotor to handle high temperatures generated during aggressive braking without cracking or warping. The rotor’s Thermal Stability Profiling (TSP) process ensures a precise, balanced surface that reduces vibrations and brake judder.

DBA’s signature Kangaroo Paw ventilation system enhances airflow through the rotor, significantly improving heat dissipation compared to conventional vented rotors. This innovative design not only helps maintain optimal braking performance but also extends the rotor’s service life by preventing overheating.

Installation & Fitment

The DBA 4000 Series Plain Front Rotor is a direct replacement for the front rotors on 2005–2010 Jeep Grand Cherokee models. It installs easily using existing hardware with no modifications required, making it a straightforward upgrade for both professional mechanics and DIY enthusiasts. The rotor’s precise fitment ensures proper alignment with OEM calipers and brake pads, maintaining factory braking geometry and performance.

What's Included

• One DBA 4000 Series Plain Front Rotor (driver or passenger side as specified)
• Protective coating to prevent corrosion during storage and installation
• Installation instructions (where applicable)
