  • Is It Hard To Install a Pin Box On Your Own
    It is not hard per say to replace a pin box like the Lippert 1621 5th Wheel Pin Box part # LC1387883 on a trailer as it is just nuts and bolts but the pin boxes are pretty heavy (+/- 150 lbs). I am not sure why you are having trouble finding a service center that will do this for you as it's pretty standard practice but it is doable yourself. If you don't have a forklift which is what most will use you can call a few friends over to hold the pin box while one person unthreads the bolts...

  • Using Air Ride 5th Wheel Hitch Together With Air Ride Pin Box
    I've seen the Trailer Saver before, it looks like a great hitch but we don't have any personal experience with it. I've done some research though, and I can certainly see how a flexible linkage between the hitch and vehicle (air bags on the hitch) and a flexible linkage between the king pin and the fifth wheel (air bag in the pin box) could tend to amplify the chucking. I did some searching around, and really the only online opinions I can find pretty much mirror what Trailer Saver's...

  • Replacement For Lippert 1621 Pin Box For 16,000 lb Trailer
    We do have the right replacement for you, though for your 16,000 lb trailer you would actually need something different than the ones you mentioned. That's because the 18k pin box you mentioned is a replacement for the 1621HD, which has different wings than the 1621, and the 15.5k # LC1191191 isn't rated high enough for the 16,000 lb gross weight of your trailer. The correct replacement that is an exact fit for your 1621 and has the right capacity is the following: - Lippert 1621 5th...

  • Replacement of King Pin Box
    The Lippert 1716 5th Wheel Pin Box, # LC1324791 is is 12.5" in width. The Lippert 1621, # LC1387883 and the Lippert 1621HD 5th Wheel Pin Box, # LC1191151 are both 12" in width.

These are both typically located on a sticker on the pin box or on the king pin itself. This pin box number will usually be 3-4 numbers long and can have letters attached to it. Some very common...

  • Can B&W Companion 5th Wheel Hitch Be Used with Reese Sidewinder
    The B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter part # BWRVK3500 is not compatible with rotating pin boxes even if you lock out the turret. The reason for this has to do with the the excess torque on the single connection point and its inability to withstand this. Therefore, your best option would be to remove the rotating pin box and replace it with a standard pin box. For this, we have the Lippert 1621 5th Wheel Pin Box part # LC1191191 which is rated for 15,500 lbs and...

  • Is the Lippert 1621 an Extended Pin Box
    The extended notation you have mentioned for the Lippert 1621 5th Wheel Pin Box part # LC1387883 is in regards to the style. This is also know as the "long" style and there are several other pin boxes with this style that have similar dimensions but they are not designed to move the king pin.

The only way this extended/long style will move the kingpin further out is if you were using...

    Thanks for the photos and number, although because there are a large number of pin box manufacturers, without knowing who made it, identifying yours is only going to be possible through some measurements. Thankfully, this is a pretty simple task and will allow you to know exactly what pin box you have to get the proper replacement. I have added a link to a help article which shows you exactly how to do this, which I'll summarize for you. First, you'll need to select your pin box style,...

  • Alternate to the Andersen Ultimate 5th Wheel Trailer Hitch System on a 2021 Chevrolet Silverado 2500
    The Andersen Ultimate Connection 5th Wheel Trailer Hitch System with Adapter, # AM3200 definitely has its value in certain applications. It also, unfortunately, has its drawbacks. For your 2021 Chevrolet Silverado 2500 short bed with the OEM Prep Package I think the best option is the B&W Companion OEM 5th Wheel Hitch w/ Slider, # BWRVK3775 for 20K hitch which is more than suited for the Toy Hauler you listed. Just an FYI, the # BWRVK3715 is available too for a 25K hitch rating. This...

  • Will Lippert 1621 5th Wheel Pin Box Fit a 2016 Crossroads Reserve 27BH
    If your 2016 Crossroads Reserve 27BH has a 1621 pin box then yes, the Lippert 1621 5th Wheel Pin Box # LC1191191 will fit your application. If you have a different number (which can be found on the pin box sticker) or are unsure just let me know and I can help you find out what you have. Unfortunately when I have spoken with trailer manufacturers in the past they required detailed information about the trailer that only the owner has access to for them to confirm the pin box number.

  • Best Solution For Adding A 5TH Wheel To Gooseneck Adapter to Montana For Towing With Short Bed F-350
    The length from the center of the goose ball connection to the center of the front mounting bolts on the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94720 is the same as the length of the Lippert 1621 Pin Box # LC1387883 on your 2020 Montana High Country 294RL. At 17-3/4" you will continue to have the same amount of clearance that you have currently with your slider hitch in the towing position.

  • 5th Wheel Hitch and Pin Box for 2016 Nissan Titan XD
    If I understand correctly, you have a Curt E16 5th Wheel Trailer Hitch, # C16115 mounted in the back of a 2016 Nissan Titan XD (6.5 foot bed?). You have a Lippert 1621 Pin Box, # LC1387883, on your 5th wheel but not enough clearance for the cab. I get the impression that you have the hitch mounted on Base Rails such as # C16200. If you have a short bed truck you need, at minimum, the Curt E16 Hitch # C16115, mounted on the Curt R16 Round Tube Slider for E16 Hitches, # C16560. Another...

  • Recommended Gooseneck Hitch to 5th Wheel King Pin for Horse Trailer and Short Bed Truck

There unfortunately isn't a better option for the offset you need for best turning clearance and you may still have some restrictions based on the placement of that king pin.
