6K Conversion Kits
Upgrade your 6,000 lb axle trailer with a complete Hydrastar electric over hydraulic disc brake conversion kit. Each 6K kit is engineered for medium-duty trailers used in boat hauling, equipment transport, marine applications, and tandem axle utility configurations.
Every kit includes the 1,600 PSI Hydrastar EOH actuator, 6K axle-rated Dacromet-coated rotors and calipers, color-coded hydraulic brake lines, brake flange mounting hardware, breakaway switch and battery, wiring harness, and prewired 7-Way RV junction box. Bearings, seals, and grease caps are also included.
Hydrastar's 6K conversion kits come in both integral and slip-over configurations to accommodate different installation preferences. Marine-grade variants feature additional corrosion protection for boat trailer applications.
The actuator's sealed aluminum housing withstands harsh road and environmental conditions, and the included brake lines are triple annealed and eddy-current tested with walls 40% thicker than standard for kink-free routing. All kits comply with CFR-393 Federal Braking Requirements and meet SAE J1650 standards.
