Tow pins are an item that should be given consideration. There are two basic types, fixed and removable. Each has its benefits and downsides.


Fixed pins are tied in o the front frame structure, and are singular, centered in the bumper. They are typically capable to 80,000 lbs. of direct pull. They are not removable, and as a permanent part of the truck, are included in overall length measurements.



Removable pins come in pairs and should be used accordingly. They tie into the end of each rail assembly and are rated at 40,000 lbs. direct pull per pin. Proper use for these includes a spreader bar to properly distribute the pulling force. Since they are removable, they do not contribute to the overall length measurement. The flexibility of being removable can also lead to their weakness. Since they are removable you will most likely want to store them in the cab when not in use. I have seen many trucks with missing pins where the owner assumed that the bumper position was a safe storage receptacle.


Below is a list of the overall length laws per state. Take this center pin hitch length into account when you decide on truck length. Based upon where the vehicle will be placed into service and operate make certain it adheres to the regulations. The 45 ft. states compromise most of the middle US. If you exceed 45 feet the list of states the vehicle can be used in becomes quite small, and aside from Montana, Wyoming, North Dakota… the states are regionally separate.


No limit: GA

60 ft: WY

55 ft: MT

50 ft: ND, OH

45 ft: TX, LA, OK, KS, MO, KY, IA, MN, CO, SD, ID, UT plus VT, NH, CT, ME, and AK, HI

42 ft: IL

41 ft: Canada

40 ft: 26 remaining states
