Braked Trailer Couplings

Braked Trailer Couplings — Override Hydraulic Systems

Override couplings activate your trailer's brakes automatically when you brake in the tow vehicle. The trailer's momentum pushes forward on the coupling, which actuates the hydraulic brake system — no electrical connection required.

Coupling Range

Standard Override 2500 kg 50mm / 1⅞" $299
Duofit Override 2500 kg 50mm / 1⅞" $350
TC40 Override 2500 kg 50mm / 1⅞" $430
TC40 Snap Lock 2500 kg 1⅞" $562
