5th Wheel Pin Box - Fabex 770

I spoke with my contact at Trailair and from your serial number we were able to determine that your trailer came with a 1621 HD pin box which is a long pin box style. I was unable to obtain the exact part number for your Trailair pin box but from the…

Hi Cody; the #LC328484 is a Trailair Flex Air with a Lippert 0719 bolt pattern. Assuming that is what you have, the correct Sidewinder is the Reese Sidewinder 5th Wheel King Pin with Rotating Turret #RP34FR. What 2022 Ram model do you have? Do you…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Hi Michael; I'm sure there is a Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box that will fit your 2017 Grand Design Momentum. However, we need to identify your pin box to find the right one. Can you send me a picture of the sticker on your pin…

No, I am sorry it does not. I just spoke with Lippert and none of the Curt Helux Shock-Absorbing 5th Wheel Pin Box like item #C73RJ are compatible with gooseneck adapters like the Anderson Ultimate 5th Wheel Hitch. You would need to use a standard…

Hey Jim, When it comes to chucking I'd have to say that the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box #325-GH-8040 is going to be the better option over the Lippert/Curt Flex Air Pin Box #LC369535. The Gen-Y has a rubber torsion spring design…

The difference between the 1621 and the 1621SHD is weight capacity and how many bolts is required to mount it. The 1621 uses 4 bolts for mounting. The 1621SHD requires all 6 bolts to be used.

There should be a sticker or plate on the pin box itself that lists the manufacturer and model of the pin box. If it is not present then there are some measurements you can take to determine the model of the pin box. I have included a link that…

Alan - yes, the MORryde GooseTech #MR97MV is designed precisely for trailers using the Lippert 1621 pin box in the 14-18,000 lb GTW range. Good call verifying ahead of time. For installation you’ll want to check that the existing pin-box…

Thank you so much for the pictures! That is exactly what I need. Your 2023 Solitude 2930RL has what's called a Lippert Rhino pin box. The Rhino Box, like the Lippert 1621 you mentioned, is a specific bolt pattern and to replace it with a MORryde…

Choosing the right height setting for your 5th wheel hitch is a combination of a few different variables. First of all you want your towing setup to be as level as possible. With your Montana High Country 340BH level you will want to measure from the…

Hey Lorenzo. Your 2024 Chevrolet Silverado 3500 has what's called Pulse Wave Modulation, which will not provide the wireless cameras with the correct power it needs to run when connected. This is a power saving feature in newer trucks. To fix…
