ACDelco Silver Rear Brake Rotor — Direct-Fit GM 19255506 (1999–2006 Jeep Wrangler) Multi-Alloy, Ventilated

These ACDelco Silver rear rotors are cast and machined to match factory specifications for many 1999–2006 model-year applications. Built with a multi-alloy composition and purpose-shaped vanes, the rotor design helps move heat away from the braking surface while the non-directional ground finish reduces noise and promotes even pad contact. Each purchase includes one rear rotor; use your VIN in the Confirmed Fit tool to verify compatibility in three quick steps.

How does this rotor manage heat and reduce brake fade?

The 18A2465A uses an application-specific vane layout and multi-alloy materials that channel heat efficiently from the rotor hat to the outer ring. Better airflow lowers operating temperature, helping maintain braking power under extended use without relying on exotic coatings or treatments.

• Multi-alloy construction for improved thermal conductivity
• Optimized vane configuration to encourage airflow through the rotor
• Rounded radius edges improve structural integrity at high temperature

Will this rotor be quieter and prolong pad life?

The rotor’s non-directional ground finish reduces surface irregularities that cause vibration and squeal, resulting in a calmer pedal feel and fewer NVH issues. A smoother contact area also helps brake pads wear more evenly, which can extend pad life compared with uneven or rough rotors.

• Non-directional finish reduces noise and vibration
• Smooth surface minimizes thickness variation for even pad wear
• Balanced casting reduces harshness under braking

Is this rotor a direct replacement and how do I confirm fitment?

This rotor is designed as a vehicle-specific rear replacement that fits a number of Jeep Wrangler and related models; it corresponds to GM part number 19255506. Confirm fitment quickly by entering your vehicle VIN into the Confirmed Fit tool on the product page to ensure proper fit before purchase.

• Matches factory dimensions and mounting points for listed models
• Sold as a single rear rotor—purchase quantity accordingly
• VIN-based Confirmed Fit tool validates compatibility in three steps

What are the maintenance and pairing recommendations?

For best results replace rotors in pairs or sets per axle and inspect pads, calipers, and hardware during service. Pairing ACDelco rotors with ACDelco brake pads and properly torqued fasteners helps maintain performance and avoids premature wear.

• Replace with matching ACDelco rear pads for optimized performance
• Check caliper slides, hardware, and fluid during installation
• Follow factory torque specs and bedding procedures after install

Who this is for: Drivers and DIY technicians who need a dependable, budget-conscious rear rotor that meets OEM-style tolerances for select Jeep Wrangler and similar vehicles. This ACDelco Silver rotor is suited to everyday street use and periodic towing or trail driving where reliable cooling, quiet operation, and predictable pad wear are priorities. If you want an affordable, GM-backed replacement that’s straightforward to install and easy to confirm with your VIN, this rotor is a practical choice.
