DBA T3 4000 Series Rear Brake Rotors

2005–2010 Jeep Grand Cherokee (Excludes SRT8 Models)

Part #: DBA42531S

Overview

The DBA T3 4000 Series Rear Brake Rotors are engineered for Jeep Grand Cherokee models from 2005 to 2010, excluding SRT8 variants. These high-performance slotted rotors are designed to deliver superior braking power and enhanced durability for both street and track use. Crafted for enthusiasts and drivers who demand consistent stopping performance under extreme conditions, the T3 4000 Series offers improved heat dissipation and reduced brake fade, ensuring confidence in every stop.

Sold individually, these rotors allow you to replace one side at a time or purchase a pair for both rear wheels. The advanced design and premium materials make them an ideal upgrade over factory rotors, especially for those who push their vehicles harder or require reliable braking in demanding environments.

Key Features

The DBA T3 4000 Series Rear Brake Rotors incorporate cutting-edge technology and design elements to maximize braking efficiency and rotor longevity. Key features include:

• Slotted Surface: Precision-machined slots improve pad bite and help evacuate gases, dust, and water for consistent braking performance.
• One-Piece Construction: Manufactured as a single unit for enhanced strength and reliability under high stress.
• Advanced T3 Technology: Features DBA’s patented Thermal Stability Technology (T3) to reduce heat buildup and prevent warping.
• High-Quality Materials: Made from premium-grade cast iron for optimal thermal conductivity and durability.
• Corrosion-Resistant Coating: Protective coating on the non-friction surfaces to resist rust and extend rotor life.
• Optimized Slot Pattern: Designed to minimize brake noise and vibration while maximizing pad cleaning.
• Precision Balanced: Ensures smooth operation and reduces brake judder for a comfortable driving experience.

Construction & Design

DBA’s T3 4000 Series rotors are crafted from high-grade cast iron, chosen for its excellent heat dissipation properties and structural integrity. The one-piece rotor design eliminates potential weaknesses found in two-piece rotors, providing consistent performance under extreme braking conditions. The slotted face is engineered to maintain pad contact and improve debris removal, which helps maintain braking efficiency and rotor longevity.

Additionally, the rotors undergo a proprietary thermal treatment process that enhances their resistance to cracking and warping caused by repeated high-temperature cycles. The corrosion-resistant coating on the rotor’s hub and edges further protects against environmental damage, ensuring the rotors maintain their appearance and function over time.

Installation & Fitment

These rotors are designed as direct replacements for the rear brakes on 2005–2010 Jeep Grand Cherokee models, excluding SRT8 versions. Installation is straightforward and requires no modifications to the vehicle’s existing brake system. For optimal performance and safety, it is recommended to replace rotors in pairs and to inspect brake pads and hardware during installation.

Because these rotors are sold individually, be sure to order the correct quantity—typically two—for both rear wheels. Professional installation is recommended to ensure proper fitment and torque specifications are met.
