Our take on the Redline 5.2K Bearing Kit w/2.125in Seal | BK3-310 Redneck Trailer

A per-wheel bearing kit for 5,200 lb trailer axles. It bundles the inner bearing and race (25580/25520), the outer bearing and race (LM67048/LM67010), a 2.125 in double-lip seal and a cotter pin, so one kit covers one wheel. It suits owners repacking or replacing bearings on a 5.2K axle who want all the wear parts in one box. Buying the parts individually works too, but a matched kit removes the guesswork on part numbers.

Questions and answers

What does the kit include?
Inner bearing 25580 and race 25520, outer bearing LM67048 and race LM67010, a 10-10 double-lip seal with 2.125 in ID, and a 165649 cotter pin.
How many kits do I need?
One kit per wheel. A single-axle trailer needs two kits; a tandem axle needs four.
Will it fit my 5.2K axle?
It is built for 5.2K axles. Check that your hub takes a 2.125 in seal and that the bearing IDs match your spindle before ordering.
Do I need to pack the bearings with grease?
Yes. The kit ships without grease, so pack the bearings and add grease to the hub before assembly.
Is the seal a double-lip type?
Yes, the 10-10 seal is double-lip, which helps keep grease in and water and dirt out.
Where is the Redline 5.2K Bearing Kit w/2.125in Seal | BK3-310 Redneck Trailer cheapest?
