Which kit fits my 1" trailer spindle?

The Redline kit is built for 1" spindles using L44649/L44610 bearings and a 12192TB seal. The Fultyme kit is listed for 1" axles but does not name its bearing, so check the number stamped on your old bearing before buying.

Do I need one kit or two per axle?

One Redline kit covers both wheel ends on an axle. The Fultyme kit has only one seal and one cotter pin, so you need two kits to do both sides.

Neither maker publishes a service life. The Redline kit gives you rated loads (7,200 lbs dynamic) and a double-lip seal, which helps if you tow near capacity or launch into water. Proper bearing packing and seal condition matter more than the brand.

Is the Redline kit worth it over the Fultyme kit?

Yes for a full hub service. It costs less at the latest prices and includes two seals, two dust caps and four cotter pins. The Fultyme kit only makes sense as a single-bearing spare.

Can I use these on a boat trailer?

The Redline seal is a double-lip rubber seal with steel reinforcement, which is the type used on boat trailers. Neither kit is advertised as a full marine kit, so inspect and repack bearings after water contact.

What else do I need for the job?

Grease, a seal driver or socket, and a torque wrench for the spindle nut. The Redline kit already includes dust caps and cotter pins; the Fultyme kit does not include caps.

Redline L44649/L44610 Trailer Bearing Kit vs Fultyme RV Trailer Wheel Bearing Kit

Buy the Redline kit if you want a complete, clearly specified 1" trailer hub kit with two bearings, two seals, two dust caps and cotter pins. Buy the Fultyme RV kit only if you need a single-bearing, single-seal spare and can confirm the bearing numbers match your spindle. On latest prices, the Redline kit is the better value: $14.49 to $17.52 versus $18.04 at Explosive Powersports as of November 8, 2026.
