Question:

Are the rotors in the HSE7K-TR1kit Stainless Steel or some other material? Is the HSE7K-TR1kit a verified fit for DEX 7658660 7000# axles? 2019 Grand Design Momentum 398M Triple Axle Toy Hauler. Thank you

The hub as well as rotors are cast iron for the disc brake kit from HydraStar you asked about:

- HydraStar Disc Brake Kit w/ Actuator for Triple Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K # HSE7K-TR1

They are dacromet-coated as well to help ensure corrosion resistance. I can verify for you that the HydraStar Kit # HSE7K-TR1 does in fact fit Dexter 7,000 lb axles, as they have the correct bearings (25580 and 14125A) and grease seal (GS-2250DL) for that axle.
