Ram 2500 & 3500 HD Brake Kits
Heavy Duty Towing Needs Heavy Duty Braking
The Ram 2500 and 3500 HD are the towing platforms for owners who have genuinely heavy loads: commercial fifth-wheels, gooseneck trailers, livestock haulers, and construction equipment. The Ram 3500 dually is rated to tow up to 37,090 lbs — more than most competitors — and the Cummins 6.7L diesel delivers the torque to pull those loads. Stopping them is the other half of the equation.
Ram builds HD brakes to a commercial fleet durability standard, but those brakes still face a real thermal limit under sustained heavy towing. Ghost Rotors G11H18 drilled and slotted rotors and carbon ceramic pads close the gap between what OEM HD hardware can handle and what Cummins-powered heavy towing actually demands.
G11H18 Metallurgy: Built for Cummins Diesel Towing Loads
A Ram 3500 dually at GCWR can exceed 25,000 lbs combined vehicle and trailer weight. On a mountain grade with a loaded gooseneck, sustained braking over several miles generates thermal loads that push any brake rotor toward its limits. OEM Ram HD rotors are heavy-duty spec — but they're still single-piece castings made to a fleet cost standard, not to the ceiling of what the platform can tow.
Ghost Rotors G11H18 high-carbon iron rotor rings are cast to a premium metallurgy standard above G3000 zinc-coated OEM castings. G11H18 metallurgy provides better heat dissipation, stronger vibration damping, and superior resistance to the surface cracking and dimensional variation that develops in OEM rotors under repeated heavy-tow heat cycles. The result is a rotor that maintains consistent geometry across thousands of hard towing cycles — no pedal pulsation, no steering shimmer.
Diamond-slotted venting further evacuates heat from the pad face during extended braking — preventing the temperature spikes that drive rotor wear and pad glazing.
Carbon Ceramic Pads for Long Mountain Descents
The hardest braking scenario for any HD truck is a loaded descent — 7% grade, trailer pushing from behind, brakes on continuously for four or five miles. OEM semi-metallic pads handle the first descent confidently; by the third or fourth on a long trip, friction coefficients have degraded and the pedal travel has increased.
Ghost Rotors carbon ceramic pads maintain stable friction coefficients at the temperatures sustained downhill towing generates — above the fade threshold of OEM pads under continuous load. For Ram HD owners running commercial towing routes regularly, that consistency across repeated descents is the most important upgrade benefit.
Carbon ceramic pads last 3–5× longer than OEM semi-metallic pads under equivalent use — a significant service interval advantage for a truck that accumulates high commercial miles.
Ram 2500 and Ram 3500 HD Fitment Guide
Ghost Rotors Ram HD brake kits cover the Ram 2500 (3/4 ton) and Ram 3500 (1 ton) across current and recent generations (2019+). Front rotor diameter differs between SRW and DRW configurations; the kit is matched to your axle spec.
- Ram 2500 Tradesman / Big Horn / Laramie: Direct-fit upgrade — primary benefit is sustained fade resistance under repeated towing cycles
- Ram 2500 Power Wagon: Off-road oriented with front solid axle; confirm front rotor spec using vehicle finder — the Power Wagon uses a different front brake configuration
- Ram 3500 SRW (Single Rear Wheel): Fifth-wheel and gooseneck spec — most demanding thermal use case, greatest benefit from G11H18 metallurgy
- Ram 3500 DRW Dually: Max tow rating 37,090 lbs — front kit confirmed by year and axle; dually rear brakes are separate

Lifetime Warranty on Every HD Kit
Every Ghost Rotors Ram HD kit is backed by a lifetime warranty against manufacturing defects and structural failures. Ram HD brake replacement through dealers — especially the larger front rotor and pad spec — carries a significant cost premium. Ghost Rotors delivers premium G11H18 brake performance at a competitive aftermarket price with lifetime coverage that no dealer shelf product can match.
Free shipping within the continental US on every order. Direct bolt-on installation for all covered Ram HD configurations. Break-in procedure takes 20 minutes on any road.
