Question:

I have a Blueox sway pro I need to get the 1500-2000 spring bars. I’ve been reading that I may have to buy a new style head to make the new spring bars work. I currently have the old style head that has the small pins the hold the bars into the head. Is there an aftermarket bar that fits the old style heads? If not can I just by a new style head and the bars I need?

Hey, Scott.

We have been getting some feedback from customer where you can't mix and match the old head/bars with the newer head/bars. It would be best to go ahead and get a new the new head and spring bars.

The Blue Ox head is part # BXW4011 and the Blue Ox spring bars for the weight range you are looking for is part # BXW4014.

I did notice that the 20k system, part # BXW2000, comes with a 2-1/2" shank. What size hitch does your truck currently have?

Hey Scott, did you end up going with the new Blue Ox head and 2,000‑lb spring bars for your SwayPro setup? Your results could really help others trying to upgrade from the older style head.
