DBA42633XD
Overview:
The DBA 4000 Series Cross Drilled & Dimpled Rear Rotor is engineered specifically for Jeep Grand Cherokee models from 2011 through 2026. Designed to enhance braking performance and durability, this rotor is ideal for drivers seeking improved heat dissipation and consistent stopping power under demanding conditions. Whether you’re tackling daily driving, towing, or spirited off-road adventures, these rotors provide reliable braking confidence and extended rotor life.
DBA’s 4000 Series rotors are a premium upgrade over factory components, offering advanced features that reduce brake fade and improve pad bite. This makes them a perfect choice for Jeep Grand Cherokee owners who want to maintain optimal braking performance while enhancing the overall driving experience.
Key Features:
These rear rotors incorporate several advanced design elements to maximize performance and longevity:
- Cross Drilled Design: Precision-drilled holes improve heat dissipation and help evacuate gases and debris from the brake pad surface.
- Dimpled Surface: Unique dimples increase pad bite and reduce brake fade by promoting better pad contact and cooling.
- High Carbon Alloy: Manufactured from premium high carbon iron for enhanced thermal stability and reduced rotor cracking.
- Internal Vane Technology: Patented internal vanes optimize airflow to cool the rotor quickly during heavy braking.
- Direct Fit Replacement: Designed to meet or exceed OEM specifications for a straightforward installation without modifications.
- Corrosion Resistant Coating: Protective coating extends rotor life by resisting rust and corrosion in harsh environments.
- Balanced for Smooth Operation: Precision balanced to minimize vibrations and ensure smooth braking performance.
Construction & Design:
The DBA 4000 Series rotors are crafted from a high carbon iron alloy that offers superior heat tolerance and structural integrity compared to standard rotors. This material choice reduces the risk of cracking and warping under extreme thermal stress, which is common during aggressive driving or towing. The cross drilled holes and dimpled surface are engineered to work in tandem, enhancing cooling efficiency and improving pad bite for consistent braking feel.
DBA’s patented internal vane design further improves airflow through the rotor, accelerating heat dissipation and maintaining optimal operating temperatures. The rotors are finished with a corrosion-resistant coating to protect against rust, ensuring long-lasting durability even in wet or salty conditions.
Installation & Fitment:
This rear rotor is a direct bolt-on replacement for Jeep Grand Cherokee models from 2011 to 2026, requiring no modifications or special tools for installation. It is designed to fit perfectly with the factory brake calipers and hardware, making it an ideal upgrade for both professional mechanics and DIY enthusiasts. Proper installation ensures optimal rotor performance and safety.
