Video Transcript for Review of Blue Ox Replacement 350 lbs TW SwayPro Spring Bars - BXW4015

Hi there. I'm Michael with Today, we're gonna take a quick look at these Blue Ox replacement spring bars for your SwayPro weight distribution system. Now this kit is going to include the two spring bars lift chains and necessary hardware needed to replace your SwayPro spring bars. Now, one of the really nice things about the SwayPro system is that you can simply switch out your spring bars. So if you get a lighter trailer or a heavier trailer make sure that your a ride is gonna be nice and smooth.

You can simply switch out the spring bars so that it's got the right weight capacity for you rather than having to get a whole new system. So we do have lots of different spring bar sets that will range from tongue weight of 200 pounds up to the tongue weight of 2000 pounds. So you just need to make sure that you're getting the right set for your setups tongue weight. The bars do all look very similar. They are going to have slight thickness differences but the easiest way to tell which bar set you have they use a dot system.

So the three, 350 pound bars are not gonna have a dot, your 550 pound max tongue weight is gonna have one dot like we have here. So these are our 550 pound max tongue weight. But then on that list there you can see those dots on the right side. So it goes up to five dots for your 2000 pound tongue weight rating. So just make sure you're getting the right one for your setup so that it's not gonna be too rigid and it's going to engage properly for you.

All these sets are going to work with both your older locking pin style pivot tubes. So they've got the divot there on the top. So your locking pin, we'll grab onto that to secure these into your head unit. And they are also going to work with your newer style through pin style locking tube so that you can get that pin passed all the way through there to secure that. So whether you have the older style or the newer this will work great for you.

These are made here in the USA, so you can trust, they're made to the high quality standards. We've come to know and trust for products that are made here in the US, but more than that, because they are a Blue Ox product you can trust the are gonna fit right into your SwayPro system. And you're not gonna have any issues with it. It's just going to accommodate for either replacing spring bars that you already have or adjusting your setup for that different tongue weight. So that completes our look for today again I'm Michael with Thanks for watching..

  • How to Determine Which Blue Ox Spring Bars I Have to Determine Their Tongue Weight Capacity
    There's a surprisingly easy way you can determine exactly what spring bars you have and therefore exactly what their tongue weight rating is. The bars are going to have dimples on them (see accompanying photo) which is going to tell you the bars you have and the corresponding tongue weight capacity. No Dimples = 200 lbs to 350 lbs Tongue Weight Capacity: Spring Bars for Blue Ox SwayPro # BXW4015 1 Dimple = 350 lbs to 550 lbs Tongue Weight Capacity: Spring Bars # BXW4005 2 Dimples = 550...

  • Recommended Spring Bar Replacements For My Blue OX Sway Pro
    When it comes to replacing your spring bars you need to first know what the tongue weight rating is for your current system.

  • Does the 750 lb Blue Ox SwayPro Weight Distribution System Come with Spring Bars for Other Weights
    The Blue Ox SwayPro Weight Distribution part # BXW0756 is designed for a trailer with a tongue weight between 550 lbs - 750 lbs. If you have a different tongue weight outside of this range, you'd need to purchase new spring bars for that weight which is the case for almost all weight distribution systems, they don't come with. I have attached these for you below. 2,000 lbs part # BXW4014 1,500 lbs part # BXW4008 1,000 lbs part # BXW4007 750 lbs part # BXW4006 (comes with above) 550 lbs...

  • Clamp-On Weight Distribution System Needed for a Variety of Trailer Sizes
    We do have a weight distribution (WD) system that will fit your various trailer size needs, but if your current trailer hitch/ball mount is already hitting the ground during some of the driveways you have to turn in to I'm not sure if adding a WD system to the mix is a good idea. The shank and head unit will hit the ground and if your driveways are steep enough I doubt the bars are meant to flex that much. If you still need the WD system then the Blue Ox SwayPro systems have clamp-on brackets...

  • Recommended Weight Distribution System for Towing Car Hauler with Alternating Loads
    Using the same weight distribution system with such a drastic difference in the amount of weight you're towing can be an issue. If your load is too heavy for the system then it won't be able to do its job, go too light and it will make your trailer ride rough. The Reese Steadi-Flex you mentioned, part # RP66560, is certainly too heavy when your trailer is on the light side and may not even be enough when fully loaded. Instead I recommend using a system that you can convert based on your...
