Bulldog 1289050300 Details

The result of generations of design expertise and field experience, Bulldog’s BX1 gooseneck couplers offer flexible mounting options with the Next Generation locking plate coupler locking mechanism.  The BX1 makes hooking up, adjusting vertical height, and disconnecting quick and easy.  The new ball pocket design provides contact on both sides of the ball for substantially improved pull out strength - the only sliding-plate design that transfers part of the load to the top locking plate rather than only the bottom locking plate.

  • Maintains smooth operation over time with grease fittings for every important operating part
  • Protects against wear with enclosed locking pin mechanism
  • Guides ball into socket more easily—letting you miss by more than an inch—with bottom locking plate 50% larger than competitors
  • Allows shorter retracted length and less wasted length for trucks with high bed height via low-profile locking mechanism
  • Operates easily with one hand thanks to new locking handle design
  • Provides continuous tight ball fit with ever-increasing cam tightening locking mechanism
  • Resists theft with integrated feature to allow pad-locking the coupler to the ball (lock not included)
  • Lengthens life of locking mechanism with oil-impregnated bushings
  • Fits ball better and reduces jarring through contour-formed edge on bottom locking plate
