Lippert Tandem‑Axle 12″ Electric Brake & Oil‑Bath Drum‑Hub Kit – 7K Standard / 8K Hybrid Axles – Fits Dexter • Alko • Rockwell
Model: LP686HBALippert 12″ Electric Brake & Oil-Bath Drum-Hub Bundle for Tandem 7K-8K Axles
This all-in-one kit pairs Lippert’s proven 12″ manual-adjust electric brake assemblies with heavy-duty, oil-bath drum hubs. The brakes are engineered for axles up to 7,000 lbs. Lippert and Dexter “8K Hybrid” axles reach 8,000 lbs by combining these same 7K-rated brakes with larger 5/8″-stud hubs, thicker bearings and oil-bath lubrication. This bundle mirrors that factory configuration—so you can service standard 7K axles or 8K hybrid axles with confidence.
