this offset ball has helped towing my fifth wheel, keeping it away from the truck cab when turning or backing tight. I would highly recommend this. 938336

Top notch customer service and fast shipping. Have been ordering from etrailer for years and will continue to do so. 910225

I use this device to provide more clearance for the pin box on my 5th wheel toy hauler in conjunction with an Andersen hitch. It has eliminated the pin box hitting the rails of the pickup bed but enables me to keep the 5th wheel 4” further back from the cab—the cab would be 4” closer if I just reversed the Andersen mount. 904146

I have a plastic bed liner in my truck and I was afraid it might affect the way it fit but it worked perfect. I haven't had a chance to pull the trailer with it yet but seems to fit great. 902881

I have used the B & W 4" offset ball extention for about one year. It does what I needed it to do - move the fifth wheel back a little in order to stand behind an opened tailgate on my pickup while hooked up. I considered it a necessity with the Reese Goosebox I installed on my 2017 Chevy Silverado 3500. PROs: Fit very well in the bed of the truck. Moved the fifth wheel back a little so I could access the back of the truck with the tailgate open. Also raised the fifth wheel up just a little to provide more clearance from the bed rails to the bottom of the fifth wheel overhang. This extention is really heavy duty and is made out of thick steel. CONs: It is heavy, which is to be expected. The paint almost immediately came off the welded on hitch ball. I grease the ball with every usage and paint chips still come off the hitch ball and in to the receiver tube of the Reese Goosebox. I would buy this again, as it seems to be the only product on the market to extend the hitch back on the B & W hitches. 900962

4” offset puts my trailers back enough to keep them out of the back glass. Very happy with it. 880961

This extended ball was perfect it fit perfectly in the locking mechanism. I was informed when it shipped and had a follow up e-mail when it arrived. This is going to extent the ball in my truck back 4 inches and also lifts the ball up one inch which will allow me to back my truck up to our trailer with the tail gate down!!! Before I had to have it down then jump out and bring it up for final hook up which was a hassle. Thanks !!!!!!!!! 850715

Product was received in excellent condition. Ordered on Fri. but due to price matching and the weekend, the item was on hold till Mon am. At that time released and received on Wed. Excellent service, EXCEPT, in order to talk with a rep. takes a minimum of 30 min. on hold. Of course thats blamed on covid, kinda convenient, huh. Mr. Satisfied. 825821

We recently set up a dealer account with etrailer after having months of on going issues with our main vendor and we couldn't be more satisfied. The process was fast and easy. The customer service is beyond excellent and exceeded what we were hoping for. To sum up this review; I highly recommend etrailer for any and everyone! 826227

Wow. Does the trick. Even though it’s a small change to the pivot point of the gooseneck, it makes all the difference on my F250 short bed. No more contact with the headache rack. 818068

Works great to keep your tool box from getting smacked during a tight turn. It will also help save your tail gate. We pull a 28' living quarters horse trailer. The propane tanks, batteries and the spare hangs in front and limits your clearance when hooking up the trailer. This hitch gives you just enough extra room to back in during hitching with out crunching the gate. 816960

Product is exactly as described. Use it on my 2003 GMC 2500HD crew cab short bed to pull my 5th wheel toy hauler with a Reese Goosebox. The extra offset is great and helps with sharper turns. 762437

I'm lovin it, it matches my color scheme on my truck, I'm sure it's going to be great for use which I will be doing this weekend, I will send pictures when I get to use it 756751

I have a short bed pickup and we have one enclosed trailer with a full front. Gives me extra room for tight turns when pulling it. Don't have to worry as much for the cab striking the trailer. 735339

Fast shipping... The B&W 4in extension hitch ball is really good. I have used it a couple of times works great wish I had gotten one sooner. Problem I had was in a newer 2500hd the gooseneck was to close to toolbox and really close to rear window. With this extender ball problem is solved... 728082
