  • 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. If you take a look at the attached photo and help article that should then make things a bit more clear. The only way this extended/long style will move the kingpin further out is if you were using...

  • How to Determine Correct Replacement Fifth Wheel Pin Box
    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,...

  • 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...

  • Recommended Gooseneck Hitch to 5th Wheel King Pin for Horse Trailer and Short Bed Truck
    For your 2003 Silverado 2500 with 6 foot bed and gooseneck hitch, I recommend the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter w/ Offset - 12" to 16" Tall # CAB-C5GX1216. 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. The Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter - Single Jaw - 21,000 lbs # DM8550045 is a great option if you only need...

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.

  • 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...
