Frequently Asked Questions
What is the HDRamDS-390x36?The HDRamDS-390x36 is a complete front big-brake kit for the 2011-2019 Ram 1500 featuring a 390x36mm two-piece floating rotor and RG608 6-piston monoblock caliper from Rotora's HD Challenge series.
Will the HDRamDS-390x36 fit my 2011-2019 Ram 1500?Yes. The HDRamDS-390x36 is engineered as a direct-fit replacement for the Ram 1500 DS platform spanning model years 2011 through 2019. No cutting, welding, or custom fabrication is required.
Does the HDRamDS-390x36 include stainless steel brake lines?Yes. Stainless steel braided brake lines are included with every HDRamDS-390x36 front kit to ensure optimum pedal feel and compatibility with the larger caliper.
What caliper colors are available for the HDRamDS-390x36?The HDRamDS-390x36 is available in ten caliper colors: Zinc (standard, no upcharge), Red, White, Yellow, Orange, Green, Light Blue, Blue, Silver, and Black. All non-Zinc colors carry a color upcharge per axle.
What is the difference between Slotted and Cross-Drilled on the HDRamDS-390x36?Slotted rotors channel heat and gas for consistent fade resistance under hard braking. Cross-Drilled rotors add additional surface area cooling and are popular for street-track applications. Both patterns are available on the HDRamDS-390x36.
Is the HDRamDS-390x36 suitable for towing?Yes. The oversized 390x36mm rotor and 6-piston caliper of the HDRamDS-390x36 significantly increase thermal mass and clamping force, making it well-suited for trucks used in towing and hauling applications.
What wheel clearance does the HDRamDS-390x36 require?The HDRamDS-390x36 requires a minimum 20-inch wheel. Confirm clearance with your specific wheel and tire combination before ordering.
Does the HDRamDS-390x36 require any special break-in procedure?Yes. Rotora recommends a standard bedding procedure after installing the HDRamDS-390x36 to properly seat the brake pads to the rotor surface and achieve optimal braking performance.
