Key Features

• Complete 40-piece kit: Includes bearings, races, grease seals, nuts, washers, cotter pins, dust caps and rubber plugs to service four hubs without buying extras.
• Fits 3500 lb spindles: Designed for 1-1/16 in to 1-3/8 in trailer axles with spindle #84 and EZ-Lube style axles for broad compatibility.
• Durable bearing steel: High quality chrome steel bearings provide rugged service life and tend to run with lower noise when installed correctly.
• Double-lip grease seals: Seals are built to resist leakage and keep grease in the hub under normal towing conditions.

Who It's For

This kit is best for trailer owners, do-it-yourself mechanics, and small fleet operators who have 3500 lb Dexter-style axles or equivalent using spindle #84 and want a single purchase to service four hubs. It suits users who prefer to have spare parts on hand for routine maintenance or emergency repairs while on the road.

It may not be ideal for someone who needs a single replacement component or who has nonstandard or exact-fit diameter preferences, since a few customers reported the dust caps and certain parts run slightly larger by design and require persuasion to seat properly.

Pros & Cons

Pros

• Comprehensive kit contents remove the need to buy separate bearings and seals for four hubs.
• Quality chrome steel bearings and double-lip seals give good durability and low noise in normal use.
• Well packed for shipping, reducing the chance of bent or damaged parts on arrival.

Cons

• Dust caps are intentionally slightly larger, requiring a wood block and hammer or rubber mallet to fit, which some users found inconvenient.
• There are mixed reports about long-term durability for a small number of users, so heavy-duty commercial users may prefer OEM-specific parts.
