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.
