Detailed Product Description

This Raybestos disc brake rotor is part of the Specialty - Truck product line, which focuses on components tailored for truck and SUV applications. The vented rotor design enhances cooling efficiency by allowing air to circulate between the rotor surfaces, reducing the risk of brake fade during heavy-duty or extended braking. The rotor’s cast iron construction provides a balance of strength and thermal conductivity, essential for maintaining braking performance under load.

With a nominal thickness of 1.102 inches and a discard thickness of 1.039 inches, this rotor offers a measurable wear limit to ensure safe replacement intervals. The overall height and outside diameter specifications are engineered to match the original equipment dimensions for Jeep Wrangler and Wrangler JK models, ensuring proper fitment and function. The five mounting bolt holes and stud/lug hole quantity correspond to the factory specifications, facilitating straightforward installation.

Compatible Applications and Common Use Cases

• Replacement rotor for Jeep Wrangler and Wrangler JK brake systems
• Addresses issues related to rotor wear and thickness below discard limits
• Helps resolve brake fade caused by overheating during towing or off-road use
• Restores proper rotor dimensions for consistent brake pad contact
• Suitable for conventional brake setups requiring vented rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of rust or debris before installation. Verify that the mounting bolt holes and center hole align precisely with the vehicle hub. Measure rotor thickness to confirm it meets or exceeds the discard thickness specification of 1.039 inches. Use proper torque specifications for mounting bolts to avoid warping the rotor. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
