Question:

I have a 2019 Big Country 3360SS fifth wheel and it has to Dexter 065904 7000 lb axles and want to change to disc brakes with slip over rotors but I need to know the kit and idle rotors I would need to do the job I prefer the DeeMax. Thanks Darrell

Hey Darrel, since you like the DeeMax 7k slip on kit the part number you'd need is the # DE46AR which comes with the slip on rotors and the needed actuator and lines.

So for an idler hub what you'd want is the part # 8-231-50UC1 and you'd be set.

Thanks and which kit would have the disc hubs included with the kit? It seems that would be the better option.

@Darrell The part number for that would instead be # DE66AR.

Jameson, I was getting ready to buy the brakes but i looked at my wheels and i HAVE 9/16 18 Lug bolts. The kit and hub you suggested is 1/2" lugs. My axle is a Dexter 065904 7000# SN 132147803. What will I need to order to get the 9/16"-18 lug bolts? Thanks, Darrell

@DarrellM For a hub instead you'd want the part # AKIHUB-865-7-1-EZ-K and then for the rotor kit part # DE49YR and then for an actuator # DE75KR and then for tandem brake line kit # DE57SR and you'd be set.
