PowerStop L5172 Disc Brake Caliper - Front Right

PowerStop L5172 is a front right disc brake caliper built as an OE stock replacement for select Ram and Dodge Ram trucks. It is a direct bolt-in caliper for front-right applications, with remanufactured construction and a gray cast iron body for stock-style service and fit.

PowerStop’s Autospecialty OE Replacement Brake Calipers line focuses on restoring factory brake function with remanufactured calipers and brackets assembled in Chicago, IL. The L5172 uses a 2-piston floating design with a 59.94 mm piston diameter, phenolic piston material, and a supplied mounting bracket for the listed applications.

Detailed Description

PowerStop L5172 is engineered as a stock replacement caliper for front right brake service on 2011-2018 Ram 2500 and Ram 3500, plus 2009-2010 Dodge Ram 2500 and Ram 3500, and 2012 Ram 1500 with 8 lugs. It is remanufactured and pressure tested to verify piston operation and check for leaks before installation. The caliper is assembled with new seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel brake pad abutment clips to support consistent brake operation.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are replacing a worn front right caliper on a Ram 2500 or Ram 3500, L5172 provides an OE-style service part that matches the listed fitment and hardware configuration.
