Part #: RK7598

Overview

The EBC Ultimax Slotted Rear Rotors are precision-engineered brake components designed specifically for high-performance SUVs such as the Jeep Grand Cherokee SRT/Trackhawk (2011–2021) and Dodge Durango SRT/Hellcat (2018–2026). These rotors serve as a direct replacement for factory rear rotors, delivering superior braking performance, enhanced heat dissipation, and extended brake pad life. Ideal for drivers who demand reliable and consistent stopping power during spirited driving, towing, or occasional track use, these rotors maintain optimal brake function while minimizing noise and vibration.

Manufactured to meet or exceed OEM specifications, the EBC Ultimax rotors ensure a seamless upgrade without the need for modifications, making them a perfect choice for enthusiasts seeking a balance of performance and durability.

Key Features

Designed with advanced technology to improve braking efficiency and longevity, the EBC Ultimax Slotted Rear Rotors offer the following benefits:

• Ultimax Slotted Design: Progressively angled slots reduce air noise commonly associated with slotted rotors while enhancing brake cooling.
• Vented Construction: Internal cooling vanes promote effective heat dissipation to prevent brake fade during demanding driving conditions.
• Optimized Slot Pattern: Efficiently clears dust and debris from the brake pad surface, maintaining maximum pad grip and extending pad life.
• OE Style Disc Set: Ensures precise fitment and compatibility with factory brake pads (FMSI Pad No. D1053).
• High-Quality Materials: Made from premium cast iron for durability and consistent thermal performance.
• Exact OEM Dimensions: 350mm diameter, 28mm thickness, 63.5mm height, and 72mm center hole diameter for a perfect fit.
• Complete Rear Set: Includes both left and right rear rotors for a full axle upgrade.

Construction & Design

The EBC Ultimax Rear Rotors are crafted from high-grade cast iron, known for its excellent thermal conductivity and structural strength. Their vented design incorporates internal cooling vanes that facilitate airflow through the rotor, effectively dissipating heat generated during braking. This design reduces the risk of brake fade and ensures consistent stopping power even under heavy use.

The uniquely angled slot pattern is engineered to minimize the typical air noise associated with slotted rotors, providing quieter operation without compromising performance. Additionally, these slots help channel away brake dust and debris, ensuring optimal contact between the brake pads and rotor surface for improved braking efficiency and longer pad life.

Performance & Sound

The Ultimax slotted rotors enhance brake cooling and dust evacuation, resulting in more consistent braking performance and reduced pad glazing. The progressive slot angles significantly reduce the characteristic whistling or howling noises common with traditional slotted rotors, delivering a quieter and more refined braking experience. This makes them an excellent upgrade for drivers seeking improved performance without unwanted noise distractions.

Installation & Fitment

These rotors are designed as a direct replacement for the rear rotors on 2011–2021 Jeep Grand Cherokee SRT/Trackhawk and 2018–2026 Dodge Durango SRT/Hellcat models. They fit vehicles equipped with 5-bolt hubs and 350mm diameter rear discs, requiring no modifications for installation. Compatibility with OEM brake pads specified by FMSI Pad No. D1053 ensures a straightforward upgrade.

Professional installation is recommended to guarantee proper torque specifications and optimal brake system performance.
