Easy to Install
The CRK 20 Air Ride Upper Coupler installs easily. It comes complete, ready to be bolted on to the trailer long members.
Smooth Loaded or Unloaded
The CRK 20 has a self-adjusting shock absorber, which stiffens on a loaded truck and softens on a light or empty truck, where most damage occurs. The driver feels the greatest ride improvement when running with an empty tank.
