Do these two kits fit the same hub?

Yes. Both use the L44649 inner bearing, L44610 outer bearing and 12192-size seal, so they swap directly on the same 1.063 in spindle.

Which kit is better for a boat trailer?

The Dexter kit, mainly for the reinforced seal and included dust caps. Neither is a true marine setup, so repack and inspect seals each season.

Is the Dexter kit worth the extra money?

Usually yes if you need pins and caps. If you already stock them, the Redline kit does the same bearing job for less.

What does the 7,200 lb rating mean?

It is Dexter's stated dynamic load capacity for the kit. Your trailer's axle rating and tire rating still set the real limit.

Can I use these on an RV or camper?

Dexter lists RV and camper fitment. Redline lists trailers only, though the bearing dimensions are the same.

How often should I repack these bearings?

About every 12,000 miles or once a year, and after any water submersion. Replace the seal every time you repack.

Redline Trailer Wheel Bearing Kit L44649 L44610 12192 Seal vs Dexter Trailer Wheel Bearing Kit L44649 L44610 with 12192 Seal

Both kits use the same L44649/L44610 bearing pair and 12192 seal, so fit is identical. The Dexter kit is the better buy for most people: it adds cotter pins and dust caps, lists a 7,200 lb dynamic load rating, ISO 9001 certification and US origin. The Redline kit is the leaner option if you already have pins and caps on hand. No prices were provided for either kit, so compare live store prices before ordering.
