Daily-Drivable Ceramic Front Braking for the Highest-Output Mopar SUVs
The Rotora RP.21520.1 H2 Ceramic front brake pad brings low-dust, low-noise street performance to the factory front calipers of the Dodge Durango SRT Hellcat and Jeep Grand Cherokee Trackhawk. Engineered for the larger 6-piston front caliper fitted to these supercharged SUV platforms, the RP.21520.1 is a direct-fit OEM caliper replacement that requires no bracket or hardware modification. The H2 Ceramic compound is Rotora's reformulated street formula, delivering clean initial bite, reduced dust on wheels, and quiet operation across all weather conditions. For Durango SRT Hellcat and Trackhawk owners who demand confidence on daily commutes without compromising the stopping authority their vehicle requires, the RP.21520.1 is the correct front pad upgrade. Rotora applies the same materials science standards used in its full brake kit program to every direct-fit pad compound, ensuring RP.21520.1 owners receive the same quality foundation as a full Rotora big brake build in a pad that works with their existing calipers.

Frequently Asked Questions
What vehicles does the Rotora RP.21520.1 fit?The RP.21520.1 fits the 2021 Dodge Durango SRT Hellcat, the 2023 to 2025 Dodge Durango SRT Hellcat, and the 2018 to 2021 Jeep Grand Cherokee Trackhawk. These vehicles share a larger 6-piston OEM front caliper that is different from the caliper used on the Durango SRT 392 and Grand Cherokee SRT, which require the RP.14051 series pads.
Is the Durango SRT Hellcat caliper the same as the Durango SRT 392?No. The Durango SRT Hellcat uses a larger 6-piston front caliper than the Durango SRT 392. The RP.21520.1 is designed specifically for the Hellcat caliper. The Durango SRT 392 requires the RP.14051 series pads. Installing the wrong pad set can cause fitment problems and unsafe braking.
Is the Grand Cherokee Trackhawk caliper the same as the Grand Cherokee SRT?No. The Grand Cherokee Trackhawk uses a different, larger 6-piston front caliper than the Grand Cherokee SRT. The Trackhawk requires the RP.21520 series. The Grand Cherokee SRT uses the RP.14051 series. These pads are not interchangeable between the two variants.
Will the H2 compound provide enough stopping power for a 710-hp Durango SRT Hellcat?Yes for street use. The H2 Ceramic is engineered for the Hellcat caliper's clamping geometry and provides confident initial bite and modulation during normal and spirited street driving. If you take your Durango SRT Hellcat to track days, the H6 or H8 compound is a more appropriate upgrade due to their higher temperature ceilings.
Does the RP.21520.1 reduce wheel dust compared to stock pads?Yes. One of the primary advantages of the H2 Ceramic compound is significantly reduced brake dust on wheels compared to the semi-metallic factory pads. This is one of the most noticeable improvements owners experience after switching to the RP.21520.1.
Is bedding-in required?Yes. Rotora recommends performing 8 to 10 moderate stops from 60 mph down to 10 mph with cooling intervals between each stop, followed by 4 to 6 progressively firmer stops. Allow the brakes to fully cool before normal driving. This transfers an even layer of pad material onto the rotor surface and ensures optimal friction from the H2 compound.
Does the 2022 Durango SRT Hellcat fit the RP.21520.1?No. Dodge did not produce a Durango SRT Hellcat for the 2022 model year. The SRT Hellcat variant was offered in 2021 only, then returned for 2023 through 2025. The RP.21520.1 covers the correct production years: 2021 and 2023 to 2025.
Does this pad fit the standard Durango SRT or R/T?No. The RP.21520.1 is specific to the Durango SRT Hellcat caliper. The Durango SRT 392 uses a different front caliper (RP.14051 series), and the standard Durango R/T uses a different caliper system entirely. Always verify your vehicle's caliper type before ordering.
Installation Instructions
- Safely lift and support the vehicle on jack stands and remove the front wheels.
- Remove the brake caliper retaining bolts and carefully slide the caliper off the rotor. Suspend the caliper with a wire hook to avoid stressing the brake hose.
- Remove the old brake pads and any hardware clips or shims from the caliper bracket.
- Clean all bracket contact surfaces and sliding pins with brake parts cleaner.
- Using a piston retraction tool, carefully compress all caliper pistons evenly back into the bore.
- Install the new RP.21520.1 pads into the bracket, ensuring all hardware clips are fully seated.
- Reinstall the caliper and torque all bolts to factory specification.
- Reinstall the wheel and torque lug nuts to specification.
- Pump the brake pedal firmly until full pedal feel is restored before moving the vehicle.
- Top off brake fluid as needed and perform the recommended bedding procedure before normal use.
