DBA 4000 Series Non-Directional Rotor (FRONT)

2007–2018 Jeep Wrangler

Part #: DBA42630

Overview

The DBA 4000 Series Non-Directional Rotor is engineered specifically for the front brakes of the 2007 to 2018 Jeep Wrangler. Designed to deliver reliable stopping power and enhanced durability, this rotor is ideal for Jeep enthusiasts who demand consistent braking performance both on the street and in controlled race environments. Its non-directional design allows for versatile installation without compromising cooling efficiency or wear characteristics.

Whether you are upgrading your factory rotors for improved heat management or replacing worn components with a high-quality direct-fit part, the DBA 4000 Series rotor offers a balance of performance, durability, and style. It is an excellent choice for drivers seeking a dependable braking solution that withstands the rigors of daily driving and spirited off-road adventures.

Key Features

Crafted with advanced engineering and materials, the DBA 4000 Series rotor incorporates several innovative features to enhance braking performance and longevity:

• XG-150 High Carbon Alloyed Iron: Provides superior strength and resistance to cracking under extreme heat.
• Thermal Stability Profiling (TSP): Optimizes the rotor’s internal structure to minimize warping and improve heat dissipation.
• Patented Kangaroo Paw Ventilation: Enhances cooling efficiency by 20% and increases surface area by 30%, reducing brake fade during heavy use.
• Non-Directional Design: Allows flexible installation without affecting performance or wear patterns.
• Smooth OE-Style Finish: Offers a clean, professional appearance suitable for both street and race applications.
• Moisture-Proof Packaging: Ensures corrosion protection during storage and shipping.
• Direct Replacement Fitment: Designed to match factory specifications for easy installation without modifications.

Construction & Design

The rotor is precision-machined from DBA’s proprietary XG-150 high carbon alloyed iron, a material known for its excellent thermal conductivity and mechanical strength. This composition helps the rotor resist cracking and warping even under the most demanding braking conditions. Thermal Stability Profiling (TSP) further enhances the rotor’s durability by refining the internal grain structure, allowing it to maintain flatness and structural integrity over time.

The patented Kangaroo Paw ventilation system is a standout design feature that improves airflow through the rotor. By increasing the surface area and cooling efficiency, it reduces heat buildup that can lead to brake fade, ensuring consistent stopping power during extended use. The smooth, OE-style finish not only protects against corrosion but also provides a refined look that complements the Jeep Wrangler’s rugged aesthetic.

Installation & Fitment

This rotor is engineered as a direct replacement for the front brakes of Jeep Wrangler models from 2007 through 2018. Installation requires no modifications, as the rotor matches OEM dimensions and mounting points precisely. This ensures a straightforward swap with factory hardware, making it suitable for both professional mechanics and experienced DIY enthusiasts.

Proper installation will maintain the vehicle’s original braking geometry and performance characteristics, providing a seamless upgrade or replacement solution.
