Will this drum kit fit my 5200–6000 lb trailer axle?

Yes — the kit is built specifically for 5200–6000 lb axles using a 6-on-5.5" bolt pattern. Confirming fit requires matching a few key measurements and thread types.

• Bolt pattern: 6 on 5.5" (6 × 1/2"-20 studs preinstalled).
• Brake size: 12" x 2" electric or hydraulic brakes (brakes not included).
• Compatible OEM references: replaces part numbers like 008-201-09 and 42656-22003K.
• Fits common Dexter-style hub applications rated 5200–6000 lbs.

What components are included and why does that matter?

The kit arrives with the hub/drum assembly plus the bearing and seal hardware needed to service one axle end. Including these components saves time and helps ensure proper installation and wheel-end function.

• One 12" x 2" hub/drum with 6-on-5.5" bolt pattern and nuts installed.
• Grease seal sized 2.25" x 3.371" for secure lubrication retention.
• Inner and outer cone bearings: 25580/25520 inner, 15123/15245 outer (with races installed).
• EZ-lube grease cap included for easy hub lubrication access.

How do I install this hub/drum on my trailer axle?

Installation follows the standard hub-end rebuild procedure: remove the old hub, press or seat bearing races if needed, pack bearings with grease, install the hub over the spindle, secure with the nut and cap, and adjust endplay per the axle manufacturer's spec. If you are unfamiliar with wheel-end service, a professional installation is recommended to ensure safe operation.

• Inspect spindle and clean before installing new bearings and races.
• Pack bearings thoroughly with high-quality wheel bearing grease.
• Torque wheel studs/nuts and set bearing preload per axle instructions.
• Verify brake shoe alignment and clearance with 12" x 2" brakes (sold separately).

Who this is for: This JDMSPEED drum kit is aimed at trailer owners, fleet maintenance technicians, and DIY mechanics who need a reliable replacement hub/drum for 5200–6000 lb axles. It’s ideal when you need a direct-fit swap for worn or damaged hubs, when rebuilding wheel-ends during routine maintenance, or when upgrading to a complete replacement assembly that includes bearings, seals, races and an EZ-lube cap for quicker servicing. Always confirm axle capacity, bolt pattern and brake size before ordering to ensure compatibility and safe towing performance.
