Hey Vinh! The difference is in the axles they're designed for. The DeeMaxx Disc Brakes # DE53AR are designed for your standard 8k axle. The # DE63AR is specifically designed for the old ALKO 8k axles. Unless you have an ALKO axle on your trailer, you will want the # DE53AR.

What kind of trailer do you have?

Hi Robin! I have a 2023 Grand Design Momentum that I am upgrading the suspension and axles. Thank you for the clarification on the differences. I will be upgrading to a 8k dexter axle, so # DE53AR sounds like the right one for my application then. thank you!

@Vinh you're welcome! The # DE53AR is the correct kit for an 8k Dexter axle assuming you want 9/16" wheel bolts. If you need 5/8" wheel bolts that would be # DE88AR. If you're getting new hubs to go with the axles just make sure they match up.
