The best electric drum to hydraulic disc brake conversion kit we offer for a trailer with tandem 7,000 lb axles is the HydraStar Disc Brake Kit with Actuator for Tandem Axle Trailers part # HSE7K-T1. This is a complete kit that has everything you need so no extra trips to the store or waiting for things to arrive online. It comes with the hub/rotors, calipers, mounting brackets, brake lines, actuator, and other other hardware and fittings needed. Just add brake fluid and you're done.

do 7k and 8k used the same axle spindle, just different bearings?

@BradS There are similarities and important differences between the bearings/spindle setups used for a 7 and 8K axle. Both use the same 25580 inner bearing, but the 8K uses a bearing that has a slightly larger OD. Also, the 7K spindles can use two different grease seals depending on the diameter of the spindle surface where the seal rides, one with a 2.125 ID, the other uses a seal with a 2.25 ID seal. The 8K uses a 2.25 ID seal. So, the short answer is maybe yes, maybe no. Hope that helps explain it for you!

Hey Randy! The #DE66AR has 1/2" wheel bolts and the #DE68AR has 5/8" wheel bolts. Are you looking for a complete kit with a specific wheel bolt size? What is your axle capacity? The #DE66AR is also for 7k axles and the #DE68AR is for 8k.

The springs of the Roadmaster Comfort Ride System part #RM-2460-2570 are the standard 1-3/4 inch width and will work great with the 7k ales you have installed on your 2018 Northwood Arctic Fox 32-5M that has a 35 inch wheelbase.

Answer 12

The Roadmaster Comfort Ride systems do not add height to the trailer if that is what you are asking about. You also can't use them without the shock kits. What diameter axles do you have and what capacity?
