• Will Ultra-Fab 5th Wheel King Pin Shroud Fit Pin Box On 2012 Infinity 3750L Trailer
  I was unable to find the model for the pin box you have on your trailer from the numbers you provided either. I have attached a drawing of the dimensions of a Lippert 1621 5th Wheel Pin Box, part # LC1191191 you can check out. If the dimensions of your pin box match those on the LC1191191 then the pin box cover # LC301458 should work great for you.

• How to Adjust the Height of a 5th Wheel Trailer Pin Box
  When adjusting the height of a pin box such as # LC1191191 it is important to support the pin box when removing the bolts. I recommend 2 or 3 buddies to give you a hand and make sure no one is beneath the pin box while raising or lowering it. With the pin box supported unbolt it, raise or lower it as needed, and then put the bolts back in and tighten them down. According to Lippert use the following torque specs: Torque 1/2” bolts a minimum of 110 ft-lb. Torque 5/8” bolts a minimum of...

• Recommended Longest Extended Pin Box for a Lippert 1621 Bolt Pattern
  Hey Mike. I have a solution for you but what your asking isn't going to work. The Lippert 1716 5th Wheel Pin Box item # LC1324791 you referenced fits a 1716 bolt pattern, which is not compatible with your trailer's 1621 pin box. The closest comparable pin box that fits a 1621 bolt pattern is the Lippert 1621 5th Wheel Pin Box item # LC1191191. It's quite a bit shorter the center of the king pin on it sits 25-5/8" from the back mounting bolts and 17-3/4" from the front ones. The longest...

• 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.

• Picking Out Lube Plate for Fifth Wheel Hitch Connected to Lippert 1621 Pin Box
  Typically the size lube plate to use is recommended by the fifth wheel hitch manufacturer. Normally you want to match the size of the lube plate with about the same diameter of the hitch head's top plate. The 10 inch size is definitely the most common like the # RP83002 but for some of the Curt hitches they recommend a 12 inch plate like the part # C16722. Let me know what hitch you have and I'll see what is recommended.

• Replacement Pin Box Needed to Tow a 2018 Reflection 337RLS with a PullRite SuperLite
  I spoke with someone over at PullRite who said that they have heard from customers that a standard pin box that doesn't have any cushion actually tows better with the PullRite SuperLite 4P 20,000lb hitch that you are using. Since the hitch comes with an adapter for the king pin all that we need to know is the model number of your current pin box. This can actually be found on the pin box itself. There should be a sticker that has a series of numbers on it. It should reflect one of the...

• Easy Way to Tell Difference Between Lippert 1621 and 1716 Pin Boxes
  Easiest way it to measure vertically between the mounting holes of the pin box. If they are 2 inches apart up and down then you have a 1621. If that distance is instead 2-1/2 inches then you have a 1716. The part # LC1191191 that you referenced is for a 1621 pin box. For a 1716 instead you would need the part # LC1324791 for a similar style replacement.

• 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...

I've also shown the bolt hole spacing so you can compare it to your existing pin box.

The Trailair uses a rubber compound in the head assembly as well as an air bag and shock...
