The best way to determine whether or not a hub is going to fit your axle and spindle is to check the bearing dimensions on your current hub-since that will determine what fits on your spindle. The size/capacity of the axle is more secondary when compared the hub fitting on the spindle; you'll also want to make sure the bolt pattern works with your current wheels to avoid having to purchase new wheels.

If your current hub uses inner bearing # 25580 (1.75" inner diameter), outer bearing # 02475 (1.25" inner diameter), Inner race # 25520 and outer race # 02420, and the grease seal has the dimensions Inner diameter: 2.25" / Outer diameter: 3.376" (you'll need to measure with a digital caliper like # PTW80157 ), you will be able to use the Dexter Hub Assembly 008-399-90 , which has an 8 on 6-1/2" bolt pattern.

If your AL-KO axle has different bearings on it or a different wheel pattern, let me know what they are using and I can recommend a different hub that will work for you.

As an aside, AL-KO was purchased by Dexter several years back, so most of the stuff that's been made in the last 10 or so years is usually spot on as a replacement.

Yes, the number 42 spindle is the standard for Dexter 7k axles like what you have. For that we have the part #TRU57FR which does not have a brake flange or we have the part #TRU37FR which does have the brake flange.

The Kodiak Disc Brake Kit #K2HR712D will work with your 6k axles. Although your current outer bearing is probably a #15123, the #14125A used with this brake kit has the same inner diameter of 1.25" so it will fit your spindle. Everything else is…

The 42 spindle takes a 5,200 lb hub like part #AKHD-655-6-EZ-K and uses bearings #25580 and typically #15123. The hub kits do not include the spindle washer, lock nut, or stud nuts as those come with the spindle. Included are video resources for…

It is a good idea for both axles on a tandem axle trailer to have the same rating. Even if the 6,000 lb capacity of your axles is rated high enough for your trailer, if you have a load heavier than 2,500 lbs sitting over your 2,500 lb rated axle it…

Answer 10

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…
