DBA 4000 Series Slotted Rotor

1999–2004 Jeep Grand Cherokee 2.5L / 4.0L I6 / 4.7L V8 / 5.2L V8 / 5.9L V8

Part #: DBA4540S

Overview

The DBA 4000 Series Slotted Rotor is a premium front brake rotor designed specifically for Jeep Grand Cherokee models from 1999 to 2004, covering a wide range of engine options including 2.5L, 4.0L inline-6, and V8 engines up to 5.9L. Engineered for drivers who demand reliable stopping power and enhanced braking performance, this rotor is an ideal upgrade for both daily driving and spirited off-road adventures.

Featuring a slotted design, the rotor improves brake pad bite and helps dissipate heat more efficiently, reducing brake fade under heavy use. It is perfectly matched to Akebono front calipers (part number 4802), ensuring seamless fitment and optimal braking response.

Key Features

The DBA 4000 Series Slotted Rotor combines advanced engineering with durable materials to deliver consistent performance and longevity. Key features include:

• Precision-machined slots to enhance pad bite and improve braking efficiency
• High-quality iron casting for superior heat dissipation and durability
• Optimized slot pattern to reduce brake dust buildup and maintain rotor surface cleanliness
• Direct fit for 1999–2004 Jeep Grand Cherokee front axle with Akebono calipers
• Corrosion-resistant coating to protect against rust and extend rotor life
• Balanced design to minimize vibration and noise during braking
• Compatible with a wide range of brake pads for versatile upgrade options

Construction & Design

Manufactured from premium-grade iron, the DBA 4000 Series rotor is engineered to withstand the rigors of both on-road and off-road driving. The slotted surface is carefully designed to channel away gases and debris generated during braking, maintaining consistent contact between the pad and rotor. This design not only improves braking performance but also helps maintain cooler operating temperatures, reducing the risk of warping and extending rotor lifespan.

Each rotor undergoes a rigorous quality control process including dynamic balancing and precision machining to ensure a perfect fit and smooth operation. The corrosion-resistant coating further protects the rotor from environmental damage, making it a reliable choice for all weather conditions.

Installation & Fitment

The DBA 4000 Series Slotted Rotor is a direct replacement for the front rotors on Jeep Grand Cherokee models from 1999 to 2004 equipped with Akebono front calipers (part #4802). Installation requires no modifications, making it a straightforward upgrade for professional mechanics and experienced DIY enthusiasts alike. Proper torque specifications and brake system inspection are recommended during installation to ensure optimal performance and safety.
