Hello Merle, thanks for reaching out. The Hydrastar Disc Brake Kit # HSE7K-T1 you were looking at is for a standard 7K axle. The hubs use the # 25580 inner bearing, # 14125A outer bearing and # GS-2250DL (2.25" ID, 3.376" OD) seal. Most 6K axles use the same bearing and seal sizes, but they are not universal so you will want to pull one of your hubs, remove the bearings and check the numbers to be sure. As long as your axle uses the same bearing combination, seal size and hub bolt pattern, the # HSE7K-T1 kit will work great.

If your axle uses different bearings, just let me know in the comments below and I am happy to look into it.

I am looking at DeeMaxx Disc Brake Kit - 12" Rotor - 6 on 5-1/2 - Maxx Coating - 6,000 lbs since I have dual axle is the 1600 psi actuator strong enough to run two. Also I was wondering which option is better a grease hub or a oil hub? Thanks Merle Perkins

@MerleP Yes, a 1,600 PSI actuator is strong enough for running 2 braking axles. The DeeMaxx Disc Brake Kit - 12" Hub/Rotor - 6 on 5-1/2 - Maxx Coating - 6,000 lbs # DE28YR you mentioned is intended to be used with grease so I recommend sticking with that.
