iBroPrat 4-Set Trailer Hub Bearing Kit for 3,500 lb Spindles — L68149/L44649, 32-Piece with Seals & Dust Caps

The iBroPrat 4 Sets 3500 LB L68149 L44649 Boat Trailer Axle Bearing Kits is a complete 32-piece hub bearing kit designed to service four 3,500 lb trailer hubs with seals, caps, plugs and hardware for a single, cost-effective repair.

If you tow a boat or utility trailer with standard 3,500 lb #84 spindles, this kit collects everything needed to refresh bearings on four wheels in one purchase. Instead of sourcing individual bearings, races and seals from multiple suppliers, this set bundles L68149 and L44649 inner/outer bearings, corresponding races, grease seals, dust caps, cotter pins and rubber plugs to simplify maintenance and reduce downtime.

What exactly is included in the 32-piece iBroPrat kit?

The kit contains four complete bearing assemblies and spare hardware to service four hubs. All parts are matched for compatibility with 1-1/16" to 1-3/8" trailer axles using a 3,500 lb spindle.

• 4 × L68149 inner bearings
• 4 × L68111 inner races
• 4 × L44649 outer bearings
• 4 × L44610 outer races
• 4 × grease seals (171255TB, 1.719" I.D.)
• 4 × dust caps (1.98" diameter)
• 4 × cotter pins and 4 × rubber vent plugs

How does this kit save time and money compared with buying parts separately?

Buying a full four-hub kit reduces per-piece cost and removes guesswork about matching races and seals. You get complete sets for four wheels in one shipment, eliminating repeated ordering and minimizing shipping fees.

• Bulk pricing versus single-piece purchases
• All matching bearings and races to avoid compatibility issues
• Extra caps and seals included to replace worn or damaged components

Are these bearings and seals durable for boat trailer use?

Components are manufactured to industry tolerances and the seals use a double-lip design that helps retain grease and resist water intrusion. The bearings and races are precision-made to reduce noise and promote long service life when installed and maintained properly.

• Precision bearing manufacturing for smooth rotation
• Double-lip grease seals to limit leaks and contamination
• Durable dust caps and rubber plugs to protect hub internals

How simple is installation for a DIY trailer owner?

Installing hub bearings and seals is a routine trailer maintenance task for anyone familiar with axle work and basic tools. The kit ships with all necessary replacement parts, but installers should have a hub puller, bearing packer or grease gun, torque wrench and service manual for correct procedures and torque specs.

• Fits standard 1-1/16" to 1-3/8" trailer axles with #84 spindle
• Includes caps and cotter pins so no extra hardware is required
• Pack bearings with quality grease and follow torque guidelines

Who is this for: The iBroPrat 4-sets kit is aimed at boat owners, RV and trailer enthusiasts, fleet operators, and DIY mechanics who need a reliable, cost-effective way to service four trailer hubs at once. It’s ideal for routine maintenance, pre-season inspections, or replacing worn bearings on trailers with 3,500 lb axles and #84 spindles. If you prefer a single, matched source for bearings, races, seals, caps and hardware to avoid mismatches and repeated shopping, this kit provides that convenience along with spare caps and plugs as backups. For professional shops, the bulk set reduces reorder frequency and streamlines common repairs.

If you have specific axle measurements or unusual hub components, confirm spindle and seal dimensions before installation. For any product concerns or assistance, iBroPrat offers warranty support and replacement options to ensure satisfaction.
