Care information

To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:

  • Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
  • Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
  • For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
  • Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
  • Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
  • After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
  • If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

This brake assembly fits most standard 7,000 lb trailer axles that use 12" × 2" electric brakes with a 5-bolt mounting flange. Please verify your axle rating and brake dimensions before ordering. If you're unsure, send us your axle tag or hub information and we'll help confirm compatibility.
Yes. It is compatible with many standard Dexter, Lippert, Rockwell American, AL-KO, and other 7,000 lb trailer axles that use a standard 12" × 2" brake assembly. Always verify your axle specifications before purchasing.
Yes. This is a self-adjusting electric brake assembly, which automatically maintains proper brake shoe clearance during normal operation. This reduces maintenance and helps provide consistent braking performance.

Product Overview: 

Replace or service your 3,500 lb trailer axle hub with the Dexter K08-248-1G 3.5K Pre-Greased Idler Hub Kit. Designed for compatible 3.5K trailer axle applications using a #84 spindle, this complete hub assembly features a 5 on 4.5" wheel bolt pattern and 1/2"-20 wheel studs. Dexter identifies the K08-248-1G specifically with this 3.5K, #84 spindle configuration. 

The kit uses an L68149 inner bearing and L44649 outer bearing with a 1.72" double-lip grease seal. Dexter's pre-greased hub kits are supplied with the bearings and seal installed and pre-greased, allowing the hub to be installed directly from the box with less bearing preparation and cleanup. 

The K08-248-1G includes both standard and E-Z Lube® grease caps, an E-Z Lube® rubber plug, five 60-degree cone wheel nuts, and spindle retention hardware including a retainer nut, hex nut, slotted nut, D-washer, washer, and cotter pin. This retail-packaged kit provides the components required for compatible standard grease-lube and E-Z Lube® hub installations.
