R1 Concepts Rear Left Brake Rotor Drilled & Slotted (REAR): Fits Jeep Grand Cherokee 2011-2026
R1 Concepts Rear Left Brake Rotor Drilled & Slotted
2011–2026 Jeep Grand Cherokee 5.7L Hemi, 2.0L Turbo, 3.6L V6
Part #: 631-42045L
Overview
The R1 Concepts Rear Left Brake Rotor Drilled & Slotted is engineered to provide enhanced braking performance and improved heat dissipation for Jeep Grand Cherokee models from 2011 through 2026. Designed specifically for the rear left position, this rotor is an ideal upgrade for drivers seeking better stopping power, reduced brake fade, and increased durability under demanding driving conditions.
Whether you drive a 5.7L Hemi, 2.0L Turbo, or 3.6L V6 engine variant, this rotor fits precisely to ensure optimal compatibility and performance. It is perfect for enthusiasts who want to maintain safety and control during spirited driving or daily commuting.
Key Features
R1 Concepts combines advanced design with quality materials to deliver a brake rotor that meets the needs of Jeep Grand Cherokee owners. Key features include:
- Drilled holes to improve heat dissipation and reduce brake fade during heavy braking
- Slotted surface to help remove brake dust, water, and debris for consistent pad contact
- Precision-machined for a perfect fit and smooth braking performance
- Durable silver finish that resists corrosion and enhances rotor longevity
- Engineered specifically for rear left installation on compatible Jeep Grand Cherokee models
- Compatible with multiple engine options including 5.7L Hemi, 2.0L Turbo, and 3.6L V6
- Improves overall braking response and pedal feel
- Maintains OEM specifications for rotor thickness and diameter
Construction & Design
This brake rotor is crafted from high-quality cast iron, known for its excellent thermal conductivity and strength. The drilled and slotted design enhances airflow around the rotor surface, allowing heat to escape more efficiently and reducing the risk of warping under extreme conditions. The silver coating provides an extra layer of protection against rust and corrosion, ensuring the rotor maintains its performance and appearance over time.
R1 Concepts employs precision CNC machining to guarantee exact dimensions and surface flatness, which helps prevent vibrations and uneven pad wear. This attention to detail ensures a smooth, quiet braking experience while maximizing rotor lifespan.
Installation & Fitment
Installation of the R1 Concepts Rear Left Brake Rotor is straightforward and designed to fit directly onto the rear left hub of Jeep Grand Cherokee models from 2011 to 2026 with 5.7L Hemi, 2.0L Turbo, or 3.6L V6 engines. No modifications are necessary, making it a direct bolt-on replacement for worn or damaged rotors.
For best results, it is recommended to replace brake pads simultaneously and have the rotors installed by a qualified technician or experienced DIYer. Proper torque specifications and brake system bleeding should be followed to ensure optimal braking performance and safety.
What's Included
- One (1) Rear Left Drilled & Slotted Brake Rotor
Ideal For
This rotor is ideal for Jeep Grand Cherokee owners who want to upgrade their braking system for improved heat management and consistent stopping power. It suits daily drivers, weekend adventurers, and enthusiasts who occasionally tow or carry heavy loads. The drilled and slotted design also appeals to those who want a rotor that performs well under both wet and dry conditions while maintaining a clean, aggressive look.
