DEEPDREAM Trailer Bearing Kit 4-Set for 3500 lb Axles (#84 spindles) — L68149/L44649 Bearings, 171255TB Seals

DEEPDREAM 4-set trailer bearing kit supplies the bearings, races, seals, nuts, washers, cotter pins, dust caps and plugs needed to service four 3500 lb trailer hubs with #84 spindles.

If you maintain boat or utility trailers rated up to 3,500 lb, this comprehensive kit groups the common bearing sizes L68149/L68111 (1-3/8") and L44649/L44610 (1-1/16") with matching 171255TB grease seals and all hardware required for four hubs. The kit is intended for axles using spindle #84 and is built from chrome steel bearings and double-lip grease seals to resist wear and help retain lubricant under normal towing conditions. It’s sold as a value pack for routine maintenance, axle rebuilds, or replacing worn bearing sets before a trip.

How do these bearings fit my trailer axle?

This kit includes the two most common bearing/race sizes used on 3,500 lb axles: L68149 with L68111 (1-3/8") and L44649 with L44610 (1-1/16"). Each set matches a #84 spindle application so you can identify compatibility by spindle diameter and bearing number. Bearings and races are paired to seat properly and reduce wobble when tightened to specifications.

• Includes 4x L68149 bearings and 4x L68111 races (1-3/8").
• Includes 4x L44649 bearings and 4x L44610 races (1-1/16").
• Designed for spindles stamped #84 commonly found on 3,500 lb trailers.
• Check your axle spindle diameter and OEM bearing codes before installation.

What hardware and seal sizes are included?

The package supplies every small part needed to rebuild four hubs, avoiding multiple orders. Seals, dust caps, cotter pins and nuts match the included bearings and races so you get a complete axle servicing kit in one shipment.

• Four 171255TB grease seals (1.72" ID, 2.56" OD) for secure grease retention.
• Four dust caps (1.98") and four rubber plugs (1.18") to protect bearings and bearings seats.
• Four spindle nuts (1"), four shaft washers (1"), and four cotter pins (2.4") for safe assembly.
• Total pack: 40 pieces covering four hubs.

How durable and reliable are these components?

Bearings in the kit are manufactured from chrome steel, a material commonly used for wheel bearings due to its hardness and resistance to fatigue. The seals use a double-lip design to limit grease loss and help keep contaminants out; however, proper Grease, bearing adjustment, and periodic inspection are essential for long service life.

• Chrome steel bearings for strength and wear resistance under normal towing loads.
• Double-lip grease seals help reduce leakage and contamination entry.
• Components are pre-tested for fit and rotation; follow torque and adjustment guidelines.
• Regular repacking and scheduled maintenance extend life and safety.

Who is this for: This kit is aimed at DIY trailer owners, trailer service shops, and boaters who need a full replacement set for four hubs on 3,500 lb axles with #84 spindles. It’s useful for pre-season maintenance, replacing worn or damaged bearings and seals, or preparing trailers for heavy use. If your vehicle uses different bearing numbers or a different spindle size, confirm measurements before ordering.
