Trailer owners, this JDMSPEED hub kit is exactly what you need for those wheel bearing replacements! This set includes 2 complete idler hub kits designed for 2000 lb trailer axles with 1-1/16 inch straight spindles (important note - these are for straight spindles, not tapered ones!). The bolt pattern is 5 on 4.5 inches, which is super common for many utility and boat trailers. Each kit comes packed with everything you need: L44649 outer cone bearings (4 total), 1-1/16 inch grease seals, EZ lube grease caps with rubber plugs, and 10 cone wheel nuts with 1/2-20 thread. The bearing races and studs are already installed, saving you time and hassle. The easy lube system makes maintenance a breeze - just pop out the rubber plug and add grease when needed. These are direct replacements for most 2000 lb hubs out there, so if you're dealing with worn bearings, noisy wheels, or just doing preventative maintenance, this kit has you covered. The quality is solid, and having both hubs means you can do both sides at once for balanced performance. Whether you're fixing up an old trailer or maintaining your workhorse utility trailer, having the right hub kit makes the job so much easier. No more mixing and matching parts or worrying about compatibility - this complete kit gets you back on the road safely.
