Matched Rear Braking for the 2011-2019 Ram 1500: Rotora HDRamDS-355x32 HD Challenge Rear Brake System
The HDRamDS-355x32 HD Challenge Rear Brake System delivers purpose-built rear axle braking for the 2011-2019 Ram 1500 Classic (DS platform). A 355x32mm two-piece floating rotor and RG403 4-piston monoblock caliper provide the rear stopping force to properly balance a front big-brake upgrade or stand alone as a significant improvement over the factory rear brakes. The HDRamDS-355x32 is the rear axle counterpart in Rotora's Ram DS HD Challenge series.

Frequently Asked Questions
What is the HDRamDS-355x32?The HDRamDS-355x32 is a complete rear big-brake kit for the 2011-2019 Ram 1500 featuring a 355x32mm two-piece floating rotor and RG403 4-piston monoblock caliper from Rotora's HD Challenge series.
Does the HDRamDS-355x32 include stainless steel brake lines?No. The HDRamDS-355x32 rear kit retains the OEM brake lines. Stainless lines are included with the front kit (HDRamDS-390x36) but not the rear kit due to the rear hard-line configuration on the DS platform.
Is the HDRamDS-355x32 a direct fit for my 2011-2019 Ram 1500?Yes. The HDRamDS-355x32 is engineered as a direct-fit rear brake kit for the Ram 1500 DS platform (2011-2019). No cutting, welding, or custom fabrication is required.
What caliper colors are available on the HDRamDS-355x32?Ten colors are available: Zinc (standard, no upcharge), Red, White, Yellow, Orange, Green, Light Blue, Blue, Silver, and Black. Color upgrades carry a per-axle upcharge.
Can I use the HDRamDS-355x32 without upgrading the front brakes?Yes, but for optimal braking balance Rotora recommends pairing the HDRamDS-355x32 rear kit with the HDRamDS-390x36 front kit for a complete HD Challenge axle-to-axle upgrade.
What is the difference between Slotted and Cross-Drilled on the HDRamDS-355x32?Slotted rotors offer consistent fade resistance and are preferred for track use. Cross-Drilled rotors provide additional surface cooling and are popular for street-track builds. Both patterns are available.
Is the HDRamDS-355x32 suitable for trucks used for towing?Yes. The increased rotor mass and 4-piston caliper of the HDRamDS-355x32 significantly improve rear braking capacity over factory brakes, making it well-suited for towing applications.
What wheel size is required to clear the HDRamDS-355x32?A minimum 20-inch wheel is recommended for the HDRamDS-355x32. Verify clearance with your specific wheel and tire setup before purchasing.
