Bulldog BX1 Couplers

BX1 Adjustable Couplers (25k & 30k)

The BX1 has several great improvements over the previous model. Please watch the video below for a comparison of what makes the BX1 the best gooseneck coupler in the industry.

Effective November 2012 all PJ Goosenecks ordered with a round coupler will receive a Bulldog BX1 standard.

  • Has dual grease fittings to grease the ball and locking plate for smooth operation
  • Bottom socket plate is 50% larger than competitors, making it much easier to position the ball under the socket
  • Can be operated easily with one hand and is extremely simple to lock and unlock
  • Moving the handle to the bottom of the coupler allows for more vertical adjustment since there is no longer handle assembly on the tube. A “shorty” version is available, which is especially useful for lifted trucks.
  • The BX1 is a direct replacement for our previous Bulldog Coupler
  • The ball fits better and reduces jarring by having an additional contact point
