Bulldog BX1 Couplers


  • 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

Hydraulic Trailer Jacks


The PJ Trailers self-contained hydraulic Monster Jacks™ make raising and lowering your trailer as simple as pressing a button.

This option is becoming more popular due to the amount of energy it takes to raise and lower the trailer. Not only do Monster Jacks™ save your back, they also save you time by reducing 1-2 minutes required to raise a trailer to around 5-10 seconds. You also will no longer need to bend over to raise & lower the jack foot after the trailer has been hitched to the truck.

25,000 lbs Rigid Mount Bumper-pull 2 5/16" Coupler


If you need the 25,000 lbs bumper pull rating but don't like tow rings or pintle hooks, the 25,000 lbs 2 5/16" rigid mount coupler is a great alternative. This multi-position coupler mounts to the nose plate with four (4) 5/8" bolts.

  • 25,000 lbs rating
  • Three vertical positions available
  • Mounting bolt holes are 4.5" apart

Pintle Ring Couplers


Pintle/Tow/Lunette rings give you full range of motion across uneven terrain that might cause a ball coupler to bind or break. Tow rings are typically more common on our higher GVWR trailers (14,000 - 30,000 lbs) and are the coupler of choice for most dump trucks.

Almost every PJ Trailer can be ordered with a pintle/tow ring.

Trailers built with 12" I-beam frame receive the face mount ring that rates at 36,000 lbs. Trailers built with 6-8" channel or I-beam receive a channel mount tow ring that rates at 20,000 lbs.
