  • Best 5th Wheel Hitch for Sidewinder on 2020 Ford F-350 Short Bed With Factory Prep Package Pucks
  • Let's go ahead and start with the best 5th wheel hitch for your 2020 Ford F-350 short bed with the factory prep package to use with a Sidewinder, which is the B&W Companion OEM 5th-Wheel Hitch for Ford Super Duty Prep Package # BWRVK3300. This hitch - which has a 20,000 lb capacity - is considered by most to be the best 5th wheel hitch on the market because of its immense jaws and cushioned bushings, which combine to give you the most comfortable and quiet towing experience possible....

  • Are Replacement Parts Available for the Trailair Air Ride 5th Wheel Pin Boxes
  • The reason that you cannot find the replacement shaft is because Lippert does not offer this separately. If the shaft is worn or damaged then it is time to replace the pin box. There are only very minimal replacement parts for these pin boxes (valve part # LC156740, shock part # LC177223, airbag part # LC432404) and this is intentional to discourage home repairs on such a critical component. That said, this might be a good to time to upgrade from the Trailair Air Ride 5th Wheel Pin...

  • Does Reese Goose Box Move Trailer Closer to Truck
  • A Reese Goose Box is not going to move your trailer closer to your Dodge Ram 2500. For example, as you can see by the accompanying photos the Reese Goose Box # RP94720 measures about 18-1/2 inches from the first bolt holes to the center where the ball attaches while the pin box it replaces, the Lippert 1621 # LC1191191 pin box it replaces measures a very similar 17-3/4 inches from the first bolt holes to the center of the king pin. To determine what the correct Reese Goose Box is for...

  • Replacing a SPB72-1621LD Pin Box with a Rota-Flex or a MORryde Pin Box with Chucking in Mind
  • If you're comparing the Tailair Rota-Flex that replaces a 1621 or 1621HD Lippert pin box, part # LC328330, with the MORryde equivalent (part # MR64VR for 5th-wheel trailers with up to 11,500-lb GVWR, and part # MR84VR for 5th-wheel trailers with 14,001 to 18,000-lb GVWR), then I recommend going with the Trailair. The Rota-Flex is built with chucking and road shock in mind, so it utilizes a pivoting head with a built-in rubber compound. The pivoting head allows for controlled movement...

  • Replacement Trailair Flex Air Pin Box for 2021 Keystone Montana 3120RL
  • In order to choose the correct Trailair Flex Air pin box like the # LC328492, or any other pin box for that matter, is by checking the spec sticker on the current pin box for a model number. We don't have a database that tells us what pin box is on specific trailers, so you would need to either find the number on the sticker/plate or you can take some measurements of the bolt patterns to determine which one you've got. I've linked a brief article that explains this process. The Trailair...

  • Cushioned Sidewinder Recommendation for Grand Design Solitude Fifth Wheel

  • Trail Air Flex Air Replacement for Lippert 1621 OEM 5th Wheel Pin Box
  • The pin box shown in the photo you provided (thanks for that, by the way!) does indeed show a Lippert 1621 OEM pin box. The Lippert # LC369535 Flex Air you'd looked at is the correct replacement for a Lippert 1621 OEM pin box. However, since your OEM pin box only has a 15.5K capacity, there's really no reason to spend more for the 21K version. I'd recommend saving a few bucks and going with the 18K version, part # LC328492 which would still work perfectly for you. I've linked to a...

  • Will the Reese Sidewinder 5th Wheel King Pin Work With a 2020 Ford F-150 5-1/2' Bed
  • Yes, the Reese Sidewinder 5th Wheel King Pins will work with a 2020 Ford F-150 with 5-1/2' bed. In fact, it is one of the only options which will allow for full ninety degree turns. Please note, in order to choose the correct one you need to know the pin box type (Lippert 1621, 1716, 1116, etc). If you have a 1621 then use part # RP34FR or if you have a 1716/1116 then use part # RP77FR. If you don't already have a 5th wheel hitch picked out, I recommend the B&W Patriot 5th Wheel Trailer...

  • Towing a 2018 Keystone Fuzion 424 Toy Hauler with a 2015 Ram 3500 Short Bed
  • Using a Reese Sidewinder with a B and W Companion hitch is the perfect setup for towing your 2018 Keystone Fuzion 424 Toy Hauler with your 2015 Ram 3500. Though you have a short bed (6-1/2 foot), I recommend the Companion without the sliding feature, part # BWRVK3600. The reason you can use this one is because the Sidewinder has enough clearance to make up for the hitch not sliding. I've included a link to a video installation of this hitch. If, however, you decide to go with a pin...

  • Comparison Between Trailair Flex Air and Gen-Y Executive Replacement Pin Boxes
  • Because it's lighter, less expensive, has fewer moving parts and is mechanically less complicated I'd recommend going with the Gen-Y # 325-GH-8040 shock absorbing pin box versus a Trailair Flex Air like part # LC328492. The Trailair features a pin box that cushions most of the bouncing and jarring forces. Over time, air bags can become brittle and puncture while the Gen-Y uses technology that's similar to torsion axles, using internal bumpers that limit bounce and help to isolate the...

  • Can I Use the Mopar M20 5th Wheel Hitch with a Reese Sidewinder?
  • Unfortunately the Mopar M20 hitch you have is the same hitch as the Curt Q20 # C16130 hitch, which has a spherical axial bearing to improve the pivoting of the hitch head; because of this 360-degree pivot, it is not compatible with a pivoting pin box like the Reese Sidewinder # RP34FR. It is not possible to lock out the head with any type of wedge, so there would be two pivot points in the towing setup, which would not work. Because of the shorter bed in your 2019 Ram 3500, you do need...

I'd recommend part # RP77FR which would be compatible with the B&W Companion for Ford Pucks, like part # BWRVK3300. You'll also need a B&W specific wedge, part # SWW-06 to prevent the king pin from rotating in the hitch jaws. I've linked to some videos that you might find helpful.

  • Is There an 18K Trailair Air Ride Pin Box for the Lippert 1621HD on a Forest River Vengeance 295A18
  • The Lippert 1621 and Lippert 1621HD Pin Boxes are very similar and can be used in place of one another if you drill out the lower front hole on each side of the trailer wings which is very easy to do. The difference between the two has to do with the mounting holes and weigh ratings. Therefore, if you do the above you can use the Trailair Flex Air 5th Wheel Pin Box part # LC328492 which is rated for 18,000 lbs or you can just use the Trailair Air Ride 5th Wheel Pin Box part # LC158778 as...

There are a couple of solutions. Once would be to replace your existing legs with # C16022 and a slider unit, part # C16570. This would eliminate the need for a Sidewinder.

  • Recommended Sidewinder Pin Box For A 2017 Jayco Fifth Wheel And 2021 Ram Short Bed With Ram Boxes

This will push the pivot point back back 22" allowing for better turning clearance and prevent the pin box moving side to side and striking the Ram Boxes. Since your current pin box has a Lippert 1621 bolt pattern you'll be able to use the 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret - 16,000lbs # RP61422 or The Reese Sidewinder 5th Wheel King Pin...

  • Ride Quality Of Reese Goosebox Versus Lippert Trail Air Rota-Flex and B&W Companion 5th Wheel Hitch
  • Given the choice between the Reese Goose Box and the Trail Air Rotaflex like the # LC328330 you'd looked at, I'd recommend the Goose Box for better ride quality. The Rota-Flex offers a pivoting foot plate that provides resistance against chucking, but it lacks an airbag, so any bouncing the front end of your fifth wheel does will be transferred directly to the truck. The Goose Box features dual shock absorbers to prevent chucking as well as an adjustable air bag to absorb the shock from...

Instead, you'll want to use either the # LC328330 (trailer with GVWR of less than 18000-lbs) or the # LC328329 (trailer of GVWR less than 21000-lbs).

The Sidewinder will replace your 5th wheel trailer's factory pin box, moving the pivot point back to the turret (instead of the hitch), which allows for enough clearance so your trailer doesn't contact your Ram truck.

  • Will Lippert LC328492 Trail Air Flex Air Pin Box Raise Front of 5th Wheel Higher Than OEM Pin Box
  • The 1621 and 1621HD OEM pin box both have the same bolt pattern, so since your 5th wheel will max out at 14K, you can certainly use the 18K Trail Air Flex Air, part # LC328492. According to Lippert, when the Trail Air Flex Air is fully inflated, the top of the pin box will sit about 2 inches higher than the stock 1621. That would make for a very firm ride, so it's unlikely you'd want to run that much pressure in the bag, Lippert estimates that at half full (which is where most folks...
