Redants 2-Set 4-Lug Trailer Hub Kit for 1 in BT9 Straight Axle, 2,000 lb, Pre-lubricated

Redants 2-set 4-lug trailer hub kit is a ready-to-install, pre-lubricated replacement hub assembly designed for 1" BT9 straight axles rated to 2,000 lbs.

This pair of 4-on-4 trailer hubs arrives pre-assembled with L44643 bearings and grease seals so you can mount them directly to a 1" diameter straight spindle (BT9/EZ-Lube style). Built from durable steel with a black corrosion-resistant finish, the hubs are specified for boat trailers, utility trailers, and other small trailers using a straight axle — not compatible with tapered spindles. The kit includes all fasteners and dust caps required for installation.

Will these hubs fit my trailer’s axle and bearings?

These hubs are engineered to fit 1" diameter straight spindles (BT9/EZ-Lube) and accept L44643 inner/outer bearings. They will not fit tapered spindles or axles of other diameters.

• Fits 1" straight spindle (BT9/EZ-Lube) only.
• Pre-installed L44643 bearings (inner and outer) sized for 1" I.D.
• Dust caps O.D: 1.98", grease seal O.D: 1.98" I.D: 1.25".
• Not compatible with tapered spindles or different bearing models.

What comes in the package and what tools will I need?

The kit contains everything required to mount two hubs: the hubs themselves with preinstalled bearings and grease seals, lug nuts, castle nuts, washers, cotter pins, and dust caps. Basic hand tools and a torque wrench are recommended for safe installation.

• Included: 2 hub assemblies, 8 lug nuts (1/2"-20), 2 castle nuts, 2 washers, 2 dust caps, 2 cotter pins.
• Prelubricated bearings and pre-installed grease seals save time during install.
• Recommended tools: socket set, torque wrench, bearing packer or shop rag, and pliers for cotter pins.
• Typical install time: one to two hours per side for experienced DIYers.

How durable are these hubs and how do they resist corrosion?

Manufactured from high-strength steel and fitted with rubberized seals, these hubs are coated with a black anti-corrosion finish to withstand road and marine environments. Prelubricated bearings reduce initial wear and help maintain smooth rotation out of the box.

• Black coated hub surface for improved corrosion resistance and aesthetics.
• High bearing accuracy lowers friction and noise during towing.
• Rubber grease seals keep moisture and contaminants out of the bearing cavity.
• Prelubrication minimizes break-in wear and speeds installation.

Are there any important installation or safety notes I should know?

Install only on straight spindles of the correct diameter and torque the lug and axle nuts to manufacturer specifications. Inspect seals and bearings periodically, and replace any damaged components before towing. This kit is rated for 2,000 lbs per axle application when properly installed and maintained.

• Confirm spindle is 1" straight (BT9/EZ-Lube) before purchase.
• Torque lug nuts and castle nut to your trailer manufacturer’s specs.
• Check dust cap seating and cotter pin alignment after installation.
• Regularly inspect for wear, seal damage, or excessive play in bearings.

Who is this for? If you own a small boat, utility, or landscape trailer with a 1" straight spindle and need a quick, complete replacement, this Redants dual-hub kit is suited for DIYers and professionals who want preassembled, prelubricated hubs that reduce install time. It’s ideal for routine maintenance, axle rebuilds, or upgrading worn hubs — provided the axle is the correct straight-spindle type.
