  • Does Using an Offset Gooseneck Ball Change where the Pin Weight is Carried in the Truck Bed
    If you were to use the 4 inch offset ball # BWGNXA4085 the pin weight on the ball will not be changed. What will change is where the weight is carried on the truck. Using the offset ball will put more weight 4 inches back from the center of the gooseneck ball hole in the truck bed. This may or may not affect the truck. Some things that could happen include reduced steering and braking and headlights angled upward. If the weight is far enough behind the rear axle it can lift the front...

  • Comparing Reese Goose Box Pin Box to Andersen Ultimate for Ram 3500 Short Bed Turning Clearances
    The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94720 for Lippert 1621, 1621HD, and 0719 pin boxes will not increase your turning clearances by itself beyond the Andersen Ultimate hitch you have. The distance from the center of the hitch ball coupler to the center of the first row of bolt holes is 17-3/4 inches. The biggest benefit is the air ride suspension along with one less moving part. The only way to increase this is to use an offset hitch ball like the...

  • Compatibility of B&W Gooseneck Hitch and Offset Ball with Andersen Ultimate Hitch on 2018 F-150 5.5
    For your 2018 Ford F-150 with 5.5 foot bed, the B&W Turnoverball Underbed Gooseneck Trailer Hitch w/ Custom Installation Kit # BW77FR is the correct fit. You will want to use the 4 inch offset ball # BWGNXA4085 because the bed is shorter than 6 feet. This offset ball will work with the Andersen Ultimate Hitch but you will still need to be careful with turning clearances due to the short bed and Super Crew Cab. The Andersen hitch will require the shorter 3237 coupler tube in place of the...

  • Can a B and W Extend a Goose Goosneck Coupler be Used with a 4 inch Offset Gooseneck Ball
    I spoke with my contact at B and W and was told that the Extend a Goose # BWTEXA4200 and the 4 inch offset ball # BWGNXA4085 can be used together. However, the pivot point of the trailer will still only be 4 inches back from its original position meaning that you will get 4 inches of true offset, not 14.

  • Correct 4" Offset Ball for a B&W Turnoverball Hitch on a 2013 Ford F-150
    No, you'll need a longer one since you have a Ford truck. The correct 4" Offset Ball for B&W Turnoverball on a 2013 Ford F-150 is item # BWGNXA4085. The 4" Offset Ball for B&W Turnoverball Gooseneck Trailer Hitch for Dodge Ram 1500 item # BWGNXA4685 has a significantly shorter tube so it won't reach the locking pin.

  • Gooseneck Hitch Fit for 2019 Ram 1500 With 5-1/2 Foot Bed
    There is only one gooseneck hitch that is confirmed to fit your 2019 Ram 1500 with a 5-1/2 foot bed (as of July 2019), the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1319. The cut out of the instructions show where the hitch ball will be when installing this. Since you have a 5-1/2 foot bed you will need the B&W Extend-A-Goose Gooseneck Coupler # BWTEXA4200 which has a 10" offset, in order to give you a way to make a turn with a gooseneck hitch installed. This coupler will...

  • Offset Gooseneck Ball for 2021 Ram 3500 With OEM In Bed Prep
    The Curt Above-Bed Gooseneck Trailer Hitch for Fifth Wheel Rails # 16055 can be used with a set of in bed rails. This will give you a 3" offset. The other option would involve putting an offset adapter on to your gooseneck trailer. Something like the B&W Extend-A-Goose Gooseneck Coupler # BWTEXA4200. If you decide that this is the best option for you let me know what tube size you have on your gooseneck trailer and I will recommend a option for you.

  • Underbed Gooseneck Hitch For 2020 Ford F-150 Short Bed
    Hi James; is the 36-gallon tank a factory part and not aftermarket? If so there is an option but for aftermarket tanks I wouldn't be able to verify if there would be interference or not. So as long as your tank is a standard tank on your 2020 Ford F-150, the underbed gooseneck hitch that fits your short bed truck is the following: - B&W Turnoverball Underbed Gooseneck Trailer Hitch # BW77FR I also wanted to mention that since you have a short bed, an offset ball is highly recommended...

  • Is Removal Of The Bed Necessary To Install B&W Turnover Ball Gooseneck on 02 Ram 2500 or 09 Ram 3500
    Installation of both the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1394 for your 2002 Ram 2500 and # BWGNRK1308 for your 2009 Ram 3500 Mega Cab short bed will not require the bed to be lifted or disconnected in any way. The instructions for both do mention a lifting device is recommended but this is only for holding the center hitch section under the bed while you bolt it up to the cross rails. I recommend getting a Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring...

  • Gooseneck & 5TH Wheel Hitch Systems Compatible With Air Bag Springs On 2022 F-350 Single Rear Wheels
    Yes, you are able to use the different parts together on your 2022 Ford F-350. First you will start with the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1116. Since you have a short bed truck you may also want the 4" Offset Ball # BWGNXA4085 to gain you some additional turning clearance. While you are able to use the Demco 5th Wheel Base Rails Adapter # DM6140 with the Andersen Ultimate Connection 5th Wheel Trailer Hitch # AM3200 a better option is to use the B&W Companion...

  • Recommended Offset Gooseneck Ball for the Ram OEM Puck System
    I have a way to attach an offset gooseneck ball to the Ram OEM prep package but the 4" Offset Ball for B&W Gooseneck Hitches item # BWGNXA4085 will only fit in the square receivers for the Turnover Ball Systems. Since your 2018 Ram 2500 has the OEM prep package you will want the Gen-Y Hitch Gooseneck Trailer Hitch for Dodge Ram OEM Puck Systems item # GY83XR. This will give you a 5" offset and a 25,000 lbs capacity 2-5/16" hitch ball. It uses the pucks closest to your cab and the center...

    To add a gooseneck hitch to your 2024 GMC Sierra 2500 with a 6-3/4' bed, I recommend the B&W Custom Underbed Installation Kit item # BWGNRK1020. It has a massive 30,000 lbs capacity and fits both the 6-3/4' and 8' bed lengths. The B&W item # BWGNRK1020 includes all hardware necessary to complete installation on your truck.

    Yes, B&W does make a taller hitch ball. It is the 1" High-Rise Ball for B&W Turnoverball Gooseneck Trailer Hitch item # BWGNXA2050 which is 5-1/16" tall. The ball included with the item # BWGNRK1314 is 4-1/6 tall. This is measured from the bottom of the truck bed. No other manufacturer is compatible with B&W's hitches. You can also use the B&W Turnoverball with 4" Offset item # BWGNXA4085, which is right at 5-3/4" tall from the base of the truckbed to the top of the ball. This gooseneck...

  • Will The Gen-Y Hitch 5th Wheel to Gooseneck Pin Box Help With Clearance Issues on Short Bed Ram 3500
    The Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY38FR is not going to allow for any additional turning clearance than the 5th wheel king pin with a fixed point hitch. We have offset gooseneck ball options depending on what type of hitch you have. If your 2020 Ram 3500 has the factory puck system we do have the GEN-Y # GY83XR which will give you a 5" offset. If you have an aftermarket hitch like the B&W # BWGNRK1320 they do offer a 4" Offset Ball # BWGNXA4085 for additional...

The 4" Offset Ball # BWGNXA4085 you found is only for use in a B&W Turnoverball Gooseneck Trailer Hitch. You can combine the 5" offset of the Gen-Y above with the 7-1/2" offset of the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5GX1216 for a total offset of 12-1/2".

Instead you would want the Curt # C68ZV for a 4 inch offset option or the Gen-Y part # GY43XR for a 5 inch. These are only two options that fit.

    Congrats on the new hobby! A Reese Goose Box like item # RP85FR doesn't do much to help you with clearance and you will want all the help you can get with a short bed truck. You have two options to get more clearance when turning or backing in with your 2018 Ram 3500 with a 6-1/2' bed and I have listed them below: The first option, and the one I highly recommend if you don't already have a Reese Goosebox, is to not change out the king pin on your 2021 Alliance Paradigm 340RL and use a...

The 4" Offset Ball for B&W Turnoverball Gooseneck Trailer Hitch for Toyota Tundra part # BWGNXA4585 was for the previous generation Toyota Tundra which has a shallow hitch pin hole, it's not advised for the new generation.
