Key Features

DBA’s 4000 Series rotors incorporate innovative design and metallurgy to meet the rigorous demands of Jeep Wrangler drivers. Key features include:

• Constructed from XG-150 high carbon alloyed iron for superior strength and heat tolerance
• Thermal Stability Profiling (TSP) process to minimize stress cracks and improve rotor longevity
• Patented Kangaroo Paw ventilation system featuring 144 diamond and teardrop patterned pillars
• Up to 30% increase in surface area compared to traditional rotors for enhanced heat dissipation
• 20% improvement in cooling efficiency over straight vane designs, reducing brake fade
• Plain rotor design optimized for smooth braking and compatibility with a wide range of brake pads
• Precision-machined to ensure perfect fit and balanced performance

Construction & Design

The DBA 4000 Series rotor is crafted from XG-150 high carbon alloyed iron, a material known for its excellent thermal conductivity and resistance to cracking under extreme heat. This advanced metallurgy allows the rotor to withstand the intense stress generated during repeated heavy braking without compromising structural integrity.

DBA’s Thermal Stability Profiling (TSP) further enhances durability by relieving internal stresses that can cause warping or cracking. The rotor’s unique Kangaroo Paw ventilation design incorporates a network of diamond and teardrop-shaped pillars that increase surface area and airflow, effectively dissipating heat and maintaining optimal operating temperatures.

Installation & Fitment

This rotor is designed as a direct bolt-on replacement for the front brakes of 2007–2010 Jeep Wrangler 3.8L V6, 2013 Jeep Wrangler 3.6L V6, and 2017 Jeep Wrangler 3.6L V6 models. Installation requires no modifications and fits seamlessly with factory calipers and hardware. Professional installation is recommended to ensure proper torque specifications and brake system performance.

What's Included

• One DBA 4000 Series Front Plain Rotor (driver or passenger side)
