Will the S5172 work with my factory Ram 2500 brake pads?
Yes. The Power Stop S5172 is designed to work with your factory OEM brake pads, keeping ongoing brake maintenance costs low. New brake pads can also be installed at the same time for optimal braking performance.
Do I need to replace my brake hoses when installing the S5172?
The factory brake hoses can typically be reused if they are in good condition. Inspect your brake hoses for cracking, swelling, or leaks before reinstalling.
Are the S5172 calipers sold as a pair or individually?
The S5172 is sold as a pair, including both the driver side and passenger side front calipers with mounting brackets for a complete front axle installation.
What years does the Power Stop S5172 fit?
The S5172 fits 2009-2010 Dodge Ram 2500 and Ram 3500, 2011-2018 Ram 2500, and 2011-2018 Ram 3500. Also fits 2012 Ram 1500 models (see full fitment list).
How much stopping improvement can I expect from the S5172?
Power Stop rates the S5172 at up to 20 percent greater stopping power compared to stock OEM calipers. This is achieved through improved caliper design and the high-quality powder-coat finish that also improves heat management.
Does the red powder coat on the S5172 hold up over time?
Yes. The electrostatic powder coat finish on the S5172 is both durable and corrosion-resistant, providing long-lasting color and protection against the elements, road salt, and brake dust.
How long does it take to install the S5172?
Installation typically takes 1 to 3 hours for both front calipers. The S5172 is a direct bolt-on replacement requiring no drilling or modifications.
Do I need to bleed the brakes after installing the S5172?
Yes. Brake bleeding is required after installing new calipers to remove air from the brake lines and ensure firm, consistent pedal feel. Always use fresh DOT-rated brake fluid and follow proper bleeding procedures.
