Most Common Bearing Kit for 6K Trailer Axle  


Dexter 6K EZ LUBE axle with 8 studs, is this the right bearing kit


Helpful Expert Reply:

The most common bearings on a 6K axle are inner bearing part # 25580 and outer bearing part # 15123, along with either grease seal # GS-2250DL (2.250-inches inside diameter) or # GS-2125DL (2.125-inches inside diameter). Please refer to the linked article for more on trailer bearings and kits.

We have bearing kits with these parts combinations. Kit # BK3-100 has the larger seal and kit # BK3-110 has the smaller seal. Kit # BK3-200 that you referenced is typically used for 7K axles and has a different inner bearing.
