As a lot of people experience with Blue OX is the ball mount is too short for propper fit and operation this fixes the issue. 786998

E/trailer is wonderful to work with, the reason I did not give 5 stars is I have not got to pull my trailer with it yet. I have measured and it seems to be just where I want the height of ball. 581153

Built like a tank! Looks like great build quality and finish. Can't wait to put it to the test. Phenomenal customer service!!! 571343

etrailer was excellent with their customer service, as always. With this order I had bought a Blue OX kit with a shank that was almost 15" long. Although my truck is lifted, it still scraped in the mountains and on my sidewalk. After calling etrailer I explained that I wanted to trade out the shank. Karen tried and tried but ultimately found that I was unable to do that as the Blue Ox kit I bought is a true kit and that the shank is not exchangeable. So, I had to buy a shorter (9" x 9 hole shank) shank, Karen was very receptive of my incurred costs. She spoke to her manager and got me a slight discount to help with the unintended purchase. Plus, the new shank was here in two days. All in all, etrailer is one of the best I have dealt with. To date I have bought a roof rack, trailer hitch rack, Swagman bike hitch rack, Weigh Safe hitch, and a Weight Distribution/Sway Control hitch from them. I will keep coming back because they are that helpful and their prices are awesome! 509521

I needed the extra drop of the 9-hole BXW4002. Perfect!! Problem solved. 373104

Ask the Experts about this Blue Ox Accessories and Parts

  • Advantage of Blue Ox Weight Distribution Shank with Longer Shank
    The longer 12 inch shank on the Blu Ox # BXW4003 is just going to push the trailer a few inches further back from the rear of your truck. Adding clearance between the truck and trailer connection can be beneficial to allow space for an accessory you might have mounted in between or to be able to lower the tailgate on the truck with the trailer still connected (if this provides enough space to do on your particular setup). Other than that there's no advantage in terms of strength or...

  • Recommended Shank or Over-Under Conversion for Level Towing with Blue Ox Weight Distribution System
    Since you have the Blue Ox SwayPro Weight Distribution Shank for 2" Hitches - 9" Long - 7 Hole Adjustment # BXW4000 and are still nose high, I would normally recommend the Blue Ox SwayPro Weight Distribution Shank for 2" Hitches - 9" Long - 9 Hole Adjustment # BXW4002 to give you a total 4-1/2 inch drop whether using round bars or trunnion bars. The issue is that shank is only rated for 1,500 lbs. The only shank rated higher is the Gen-Y Torsion Weight Distribution Shank - 2" Hitches...

  • Replacement Weight Distribution Shank for Use with Blue Ox Sway Pro
    You can use a weight distribution shank from another manufacturer with your Blue Ox Sway Pro system if necessary to provide the correct coupling height and sufficient ground clearance. Based on your measurements it appears you actually need about 6-inches of drop in the shank. (We do our measurements a bit differently). Reese shank # RP3215 provides up to 5-3/4-inches of drop with trunnion bars. Dimensions of this item are shown in the linked photo.

  • Availability of Drop Weight Distribution Shanks for Blue Ox Sway Pro
    It's hard to say if you'll need more drop than what the shank you have provides. Is the newer truck taller? If the truck sits at the same height you would be fine without needing additional drop. I attached a help article that details how to determine the amount of rise/drop you would need as well, but basically if the new truck is right at 2-1/2 inches taller then the 9 hole shank part # BXW4002 would be what you would need if your current shank was maxed out. I can't see any reason...

  • Will Blue Ox Weight Distribution Shank Fit Reese WD System
    Yes, the Blue Ox weight distribution shank part # BXW4002 that you referenced uses the same bolt pattern as the Reese weight distribution systems so this would work well for you.

  • Does Equalizer Weight Distribution Head Fit Blue Ox Weight Distribution Shank
    Yes, the weight distribution manufacturers thankfully designed the shanks to their systems to all be the same dimensions. That means a Blue Ox shank like part # BXW4002 will fit an Equalizer weight distribution head.

  • Weight Capacity of Blue Ox 12 Inch and 14 Inch Shanks
    Are you looking at the Blue Ox SwayPro weight distribution shanks, like part # BXW4002? If so, Blue Ox does not give these shanks a specific class rating. All of their shanks fit 2 inch trailer hitches and have a maximum towing capacity of 15,000 lbs and a maximum tongue weight capacity of 1,500 lbs. If you are looking at the 12 inch Blue Ox High-Low adapter, like part # BX88241 or # BX88235, they have a maximum towing capacity of 10,000 lbs. The high-low adapters are not given a tongue...

  • Weight Distribution Shank with Enough Drop to Level a Trailer with a 2020 Chevrolet Silverado 2500
    If you're looking for a weight distribution shank that will be able to make up for the height difference between your 2020 Chevrolet Silverado 2500 and your trailer, then the most important factor is the drop length of the shank. To determine how much of a drop you need, you have to measure how high your vehicle's hitch and your trailer's coupler are from the ground. Measure to the inside top of the receiver tube on your truck and to the bottom of the coupler on the trailer. The difference...

  • Heavy Duty Tow Hitch Recommendation for a 2008 Ford F-350
    Yes, the Curt Trailer Hitch Receiver part # C15810 which is a fit for your 2008 Ford F-350 will allow you to tow your 2000 Holiday Rambler Aluma Lite 30SKS without the use of a weight distribution system assuming the figures you provided on the trailer are correct. This hitch has a 20,000 lbs gross trailer weight (GTW) and 2,700 lb tongue weight (TW) rating with a 2-1/2" receiver tube opening. According to the instructions for this hitch, the professional installation time is 30 minutes...

  • Comparing the Blue Ox SwayPro Weight Distribution System BXW1500 and BXW1500-S
    The only difference between the Blue Ox SwayPro Weight Distribution System part # BXW1500 and the Blue Ox SwayPro Weight Distribution System part BXW1500-S (which we don't carry) is the shank that is included with either system. The standard system (BXW1500) comes with the Weight Distribution Shank part # BXW4000 which offers up to 2" of drop whereas the extended system (BXW1500-S) comes with the Weight Distribution Shank part # BXW4002 which offers up to 4-1/2" of drop. In order to...

  • Do I Need a Longer Shank for the Blue Ox SwayPro Weight Distribution If I Raise My Trailer
    The Blue Ox SwayPro Weight Distribution w/ Sway Control part # BXW1500 has a max rise of 8" and max drop of 2". If the distance from the ground to the top inside edge of the receiver tube opening is not within the range above when compared to the distance from the ground to the bottom of the trailer coupler while level then you will need a new shank. The lift kits we offer all provide more than 1-1/4" so it would indeed appear you need a shank with more rise/drop. The Blue Ox SwayPro Weight...

  • Recommended Blue Ox SwayPro Weight Distribution System For 30 Foot Trailer
    The Blue Ox SwayPro Weight Distribution w/ Sway Control - Clamp On - 15,000 lbs GTW, 1,500 lbs TW, # BXW1506, may be a good fit for the weights and dimensions you gave. The maximum gross towing weight is 15,000 lbs and the maximum tongue weight is 1500 lbs. You will also need a hitch ball that is either 2 inches like # 63840 or 2-5/16 inches like # C40008. This system will give you up to a 13 inch rise or a 7 inch drop which will accomodate your 2 inch need from shank to top of hitch...

  • Recommended Weight Distribution System For a 2019 Airstream Classic 33FB
    The weight distribution system I recommend for a 2019 Airstream Classic 33FB is the Equal-i-zer Weight Distribution System part # EQ64FR which is rated for up to 16,000 lbs. The Equal-i-zer Weight Distribution System will perform better than the Blue Ox SwayPro Weight Distribution System part# BXW2000 and is more appropriately rated for the weight of your trailer. Please note, the Airstream Classic 33FB has an overslung coupler hence part # BXW2000 and not part # BXW2003. If you still...

  • Blue Ox Sway Pro for Airstream Flying Cloud 28 and Ford F250 with Tongue Weight of 1,300 lbs
    For your tongue weight range the correct Blue Ox Sway Pro would be the # BXW1500 but you would need a drop ball mount shank to allow you the drop you need. For that you would need the part # BXW4002.

  • Recommended Blue Ox Weight Distribution System for 1,100 lb Tongue Weight
    Though we only carry the # BXW1500 and not the 1500S model, from what I could find the only difference was that that the 1500S came with a longer shank, which is simply # BXW4002. Using this shank rather than the standard shank that comes with the # BXW1500 will give you a vertical adjustment of 11-1/4" instead of 8-3/4". The Blue Ox SwayPro # BXW1500 has a tongue weight capacity between 1,000 lbs - 1,500 lbs and if your total tongue weight was 1,100 lbs it would work well for you....

  • Shank for Use with Blue Ox Sway Pro Weight Distribution BXW0550 for 4 inch Drop
    The max drop that the Blue Ox Weight distribution system you are considering part # BXW0550 can do is 2 inches so you need a shank that can provide 2 more inches of drop than that. So for that the correct shank is part # BXW4002 and you'd be set.

  • Drop Shank Recommendation for a Blue Ox Weight Distribution System
    The shank that came with your # BXW1000 should have 7 holes in it. For a shank that you could replace yours with that would give you an additional 2 holes you would want the part # BXW4002. This would allow your trailer to sit level.

  • Can you Use the Brophy Hitch Extender to Tow a Travel Trailer
    It looks like the Brophy Hitch Reducer and Extender, part # HR26, could work for your application based on the numbers. However, this isn't something I recommend for you since the addition of an extender not only reduces your towing capacity, it also adds more sway than you want with a 30-ft. trailer. Instead, it would be better to increase the length of your weight distribution's shank (or the length of your ball coupler if your WD hitch attaches with a coupler). A good one is the...
