Refresh your rear brakes in one box with the Dynamic Friction Company Disc Brake Kit 4212-40157 (also written 421240157). This rear kit pairs a DFC GEOSPEC coated rotor with a heavy-duty brake pad and the hardware needed for the job. It's a direct-fit replacement for the 2008-2010 Dodge Ram 4500 and Ram 5500, the 2011-2026 Ram 4500 and Ram 5500, and the 2008-2010 Sterling Truck Bullet 45 and Bullet 55 — see the Buyer's Guide tab for engine-level details.
GEOSPEC coated rotor: the rotor carries a GEOSPEC coating for corrosion resistance.
HD brake pad: a heavy-duty friction pad to handle the demands of these medium-duty trucks.
Hardware included: the kit supplies the mounting hardware to complete the rear installation.
Position: cataloged for the REAR axle on the listed applications.
When your rear rotor and pad show signs of wear — pulsation through the pedal, reduced braking, squeal, or scoring — this kit replaces those components together. For even, balanced braking, service both sides of the axle as a matched set. Always confirm fitment for your vehicle before ordering.
