Blue Ox has an easy system for determining the weight capacity of your spring bars, whereas other companies may use measurements or printed capacity to assist. With Blue Ox, there is a 5 dimple system: No dimples means it is rated for up to 350 lbs total tongue weight. One dimple means it is rated for up to 550 lbs. Two dimples indicates up to 750 lbs. Three dimples indicates up to 1,000 lbs. Four dimples indicates up to 1,500 lbs tongue weight. Five dimples indicates up to 2,000 lbs total tongue weight.

I've attached videos of a couple of these sizes so you can see these dimples/notches.

350 to 550 lbs # BXW4005
550-750 lbs # BXW4006
750 to 1,000 lbs # BXW4007
1,000 to 1,500 lbs # BXW4008
1,500 to 2,000 lbs # BXW4014

I would recommend that Blue Ox TrackPro #BLU77FR simply because it does not have lift chains like the SwayPro #BXW1006. Both will do a great job but the TrackPro will have a little less movement because of the absence of drop chains. Blue Ox is a…

Answer 12

There isn't an exact science to this since each trailer is different. Most applications need about five links showing, but this isn't a set rule. For a greater load weight, use more links; for a smaller load weight, use fewer links.…
