ACDelco Silver 18A1428A rear brake rotor (GM 19261757) is a single, mill-balanced replacement rotor engineered to restore braking performance on select Chrysler, Dodge, Ram and other compatible vehicles.

Built with a multi-alloy construction and optimized internal vanes, this ACDelco Silver rotor improves heat dispersion and maintains even pad contact to help preserve pad life and reduce noise. Offered as a cost-conscious option backed by GM, the 18A1428A is designed to meet OEM-style fit and function for model years covering a broad range from 2002 to 2025, depending on vehicle application. Each listing supplies one rear rotor; verify your vehicle using the Confirmed Fit tool or your VIN before ordering.

Which vehicles does this rotor fit?

The ACDelco Silver 18A1428A corresponds to GM part number 19261757 and fits a variety of late-model vehicles across multiple brands. Compatibility varies by year, trim, axle and brake package, so always confirm with your VIN or the product fitment tool. Common fits include select Chrysler Aspen, Dodge Durango, Ram 1500 and other models that share the rear brake configuration specified by the part.

• Matches GM 19261757 for cross-reference.
• Fits numerous 2002–2025 models when specified in fitment tool.
• Sold individually as one rear rotor per order.
• Confirm fit with VIN in three steps using Confirmed Fit.

How does this rotor manage heat and wear?

ACDelco engineered the rotor with an optimized vane pattern and multi-alloy material to promote airflow through the rotor center, lowering operating temperatures under repeated braking. Reduced heat buildup helps slow rotor warping and can extend brake pad life by maintaining more consistent friction surfaces.

• Optimized vane configuration for improved airflow.
• Multi-alloy construction for balanced heat transfer.
• Mill-balanced to minimize runout and vibration.
• Non-directional finish to encourage even pad contact.

Will this rotor make my brakes quieter or reduce vibration?

The non-directional finish and mill-balanced manufacturing reduce the likelihood of uneven pad wear, brake judder and many common sources of brake noise. While rotor finish and balance can help, overall noise performance also depends on pad compound, caliper condition and installation quality.

• Non-directional finish minimizes localized contact inconsistencies.
• Mill-balanced to avoid extra weights and lower vibration.
• Works best with properly matched pads and correct installation.
• Regular inspection of calipers and hardware recommended for best results.

What should I know about ordering and installation?

This product is sold as a single rear rotor; purchasing two or four is recommended when replacing rotors on both wheels or an axle to maintain even braking. Professional installation is recommended to ensure proper torque, bedding of pads and to check related components such as calipers, hardware and wheel bearings.

• Sold individually—verify quantity needed before checkout.
• Check VIN compatibility using Confirmed Fit to ensure correct part.
• Have rotors installed and torqued by a qualified technician.
• Inspect pads, calipers and hardware during replacement to avoid rework.

Who is this for? The ACDelco Silver 18A1428A rear rotor is ideal for cost-conscious owners and independent shops looking for a GM-backed replacement that balances value and performance. It suits drivers of compatible Chrysler, Dodge and Ram vehicles who want an OEM-style rotor with improved heat management and reduced noise potential, without the premium cost of specialty or performance rotors.
