Rebuild the rear brakes in one box with the Dynamic Friction Company Disc Brake Kit 4512-40157 — a complete rear-axle package of GEOSPEC-coated rotors, DFC 5000 ceramic pads, and matching hardware. 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 fitment).

  • GEOSPEC coated rotors: Cast from a G3000/G11H18 cast iron specification and coated to a durable silver-gray finish that DFC states fights rust better than conventional paint or zinc coatings. Shipped dry and ready to install with no pre-degreasing.
  • DFC 5000 ceramic pads: 100% asbestos-free, post-cured and scorched to minimize break-in, and built with Rubber-Steel-Rubber shims for improved noise, vibration, and harshness characteristics during everyday driving.
  • Hardware included: Stainless steel hardware with PTFE coating, vulcanized rubber, and rubber-coated abutment clips, chamfered and slotted where applicable to reduce noise.
  • Non-directional finish: Machined to promote faster pad bed-in and smoother, quieter stops.

Rotors are 100% precision cut and mill-balanced. Every rotor carries a 12-month warranty against defects in material and workmanship.

Frequently Asked Questions

What comes in this kit?

This is a complete rear-axle kit: DFC GEOSPEC coated rotors, DFC 5000 ceramic brake pads, and the disc brake hardware kit — everything needed to service the rear brakes.

Which vehicles does it fit?

It's a direct-fit replacement for the 2008-2010 Dodge Ram 4500/5500, 2011-2026 Ram 4500/5500, and 2008-2010 Sterling Truck Bullet 45/55. See the Buyer's Guide tab for engine-level fitment.

Do I need to clean the rotors before installing?

No. DFC GEOSPEC rotors are processed dry and shipped dry, ready to install without additional degreasing. The coating is safely swept away by the friction material during use.

What are the benefits of the ceramic pads?

The DFC 5000 ceramic pads are asbestos-free and use Rubber-Steel-Rubber shims for improved noise, vibration, and harshness characteristics, delivering smooth, consistent pedal feel during everyday street driving.

Is the mounting hardware included?

Yes. The kit includes a DFC hardware kit with stainless steel components, PTFE coating, vulcanized rubber, and rubber-coated abutment clips, chamfered and slotted where applicable to reduce noise.
