Our take on the RGP 7,000 lb Trailer Axle Bearing Kit for Grease Hubs – 25580 & 14125A Bearings

This is a hub rebuild kit for 7,000 lb trailer axles with #42 spindles and grease-lubricated hubs. It bundles the inner bearing (25580), outer bearing (14125A), their matching races, double-lip grease seals, a dust cap with an extra plug, a tang washer, a cotter pin and a castle nut. The lube-style cap lets you add grease through the plug instead of pulling the hub, which is the main convenience over a bare bearings-and-seals kit. It suits owners doing their own bearing service or a roadside hub repair; buyers wanting pre-packed oil-bath parts or a full hub assembly should look elsewhere.

Questions and answers

Will this fit my 7,000 lb trailer axle?
It is built for 7,000 lb axles with standard #42 spindles and grease hubs. Measure your spindle and old bearing numbers before ordering, since other axle ratings use different bearings.
Does one kit do both sides of the axle?
No. One kit covers a single hub. Choose the pair option to service both sides of the axle at once.
Can I use this on oil-bath hubs?
No. The seals and lube-style dust cap are set up for grease-packed hubs. Oil-bath axles need different seals and caps.
Do I need to pack the bearings with grease?
Yes. The bearings come dry, so pack them with wheel bearing grease and add grease through the cap plug after assembly.
What bearings are in the kit?
The inner bearing is a 25580 with a 25520 race, and the outer is a 14125A with a 14276 race. The seal is a 10-36 double-lip, and the cap is a 2.5-inch OD #42.
Is a castle nut and cotter pin included?
Yes. Each kit includes a castle nut, a metal tang washer and a cotter pin so the spindle nut can be locked correctly.
