Detailed Description

PowerStop S4920 is engineered as a performance-grade rear caliper assembly for Ford F-250 Super Duty and Ford F-350 Super Duty trucks. The remanufactured caliper and bracket assembly is finished in high-temperature red powder coating and built to bolt directly in place of the original unit. The design uses new internal service components, including pistons, seals, dust boots, bleeder screws, and stainless steel pad abutment clips, to support consistent brake operation.

This part number, S4920, is intended for buyers looking for a rear brake caliper replacement that matches the original mounting style while adding a corrosion-resistant finish. The PowerStop S4920 also cross-references Monroe Shocks & Struts 172286 and 182286 for the same application.

What It Helps Solve

• Leaking or worn rear caliper assemblies
• Corrosion on the caliper housing and bracket
• Sticky or inconsistent piston movement
• Brake service needs on rear Super Duty brake systems
• Replacement of a damaged caliper with a direct-fit unit

Installation Notes
