Would the Ultra-Fab Trail Air Pin Box part # LC158778 Replace a 1621HD Pin Box  


Will this pin box work to replace a 1621 HD? My trailer is Heartland Cyclone 4000. Max wt. 18000 with stock 1621 HD


Expert Reply:

The 1621 and the 1621HD are the same dimensionally. The only difference is the weight capacities. The HD has a higher capacity.

If your trailer is within the capacity of the # LC158778 it would work fine for you. This pin box has a 21,000 lb weight capacity. Which if when your trailer is loaded and it weighs less than that you would be fine.
