Question: Can anyone tell me the distance from the back of the top receiver to the pin hole on the bottom. I need to find one over 5.5" to clear my acadia bumpe
Document: The good: it is as described. Dual 2&#34; receiver. Top one can be used for my Yakima bike rack; bottom one to pull boat, utility trailer, or other.The bad: it is so long that my trailers' safety chains are too short to reach the tow vehicle's receiver chain holes.Over all quality is excellent. I downrated it solely because it is so much longer than I can use.
Top hole not centered. Wortless for tightening no rattle bike rack pin. Contacted seller, received one email. Then no response. Cheap yes, quality no. Would not purchase again because of poor workmanship of product.
I love this thing! Perfect fit! I would recommend this to anyone who need a height adjustment. Not recommended , if you dont need a height adjustment.
This is a solid unit at a great price, but be warned that these are often imperfectly milled and may come warped. I read other people complain about this after purchasing the various versions out there, I just purchased one, and sure enough it's just a tad warped where I cannot fully insert a towbar into it. The top bike-rack mount is fine, but the main receiver is just that much bent where the only possible way I could get the towbar inserted into it would be using a sledgehammer and I'm not going to ruin my towbar.
The purchase price was great, I am not giving it 5 stars because the part that goes into your vehicles receiver was not exactly straight. The welding was not exactly straight when manufactured causing the entire bike rack to be skewed. It works as intended but has a slight variation, being off a couple degrees.
Every once and a while, something so obviously simple comes along, and it works exactly as it should. This Hitch Extension is one of those items. The user should follow the instructions that come with the unit and mount it "right side up" as it is pictured if it will be used as a double-hitch, with the piggy-back hitch riding above the main hitch. This is so that the main hitch is positioned to pull a heavy trailer, and the piggy-back hitch can then accommodate a lighter bike rack.
the hitch works as described/ the fit and finish leaves a little to be desired. Top and bottom reciever were not excactly parallel and the weld inside the reciever needed to be filed down a bit so the hitch would fit in to it.
Needed to carry 5 bikes on Suburban and tow a boat. With 2 rocket boxes on the roof, I exactly what this product provided, the ability to create 2 trailer hitch recievers. This unit is very heavy duty and I had no issues with 5 bikes and a boat loading it across country.
With a 2" drop ball mount I have to completely remove my bike rack before I can hook up/remove the trailer.2. The ball is moved about 10" back - meaning a lot more leverage. Even with my relatively light trailer (~1000 lbs loaded) there's significantly more rear axle sag when I'm using this.3. I had to get an extension for my wiring, and get longer safety chains.
Note, however, that I found an excellent alternative way to use this product. I install mine "upside down" and I ONLY use the piggy-back hitch for my bike rack. (DO NOT DO THIS IF YOU WILL ALSO TOW SOMETHING, as I do not think the piggy-back was intended for towing heavy trailers. )I do this on my Jeep Wrangler because it solves two problems. First--it positions the bike rack further aft of the rear of the vehicle, allowing my bike rack to be installed behind my (over sized) spare tire.
Answer: no
