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…

I am sorry Ira but it will not. The Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box item #GY48GR is currently the only replacement available for the Turning Point pin box. Unfortunately, there is not a normal king pin pin box that will…

Hello Randall. I had the folks at Lippert run the serial number of your pin box. Your pin box uses the 1621 bolt pattern which is quite common. If you are looking for a shock absorbing pin box replacement, you can use the Curt Air Ride 5th Wheel Pin…

Hi David; thank you for providing that information and the pictures. It looks like your Blackthorn 3101RL-OK has a GVWR of 14,040 lbs. That means the best choice for a MORryde Cushioned Pin Box is the #MR83QR. This is designed to fit a Lippert Rhino…

Hey Donald, thanks for reaching out! I recommend using the MORryde Cushioned Pin Box #MR84VR over the Curt Rota-Flex #LC328330 any day because it has better cushioning technology. Back in the day when the Rota-Flex was first released it was…

Thanks for the photo, David! The pin box on your 2022 Salem Hemisphere 369BL is a 1621 model with a 15.5K weight rating. To replace this with a Rota-Flex you need the part #LC328330. This is rated for 18K, but the extra bit of capacity won't be…

Hello Stephen. The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks #RM-2460-2580 will work great on your 2024 Brinkley Z3110 5th wheel since it has 3" diameter axles. The Comfort Ride kit will make huge improvements in ride quality…

Hey Jay. It sounds like you are on the right track here because a sidewinder pin box will be your only option for pulling your 5th wheel since you have a short bed truck with the Rambox. That said, you are right that the Reese Sidewinder cannot be…

Great question, Jeff! When the Rota-Flex first came out it renovated what a pin box could do and be, but at this point in time that technology is a little more dated and the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box #325-GH-8040 is the "new…

Thanks for the photos and information - that always makes things easier on our end! We do have a handful of replacement pin boxes that fit in place of your Lippert Rhino Pin Box. Since you don't think you'll want/need the air bag kit I…

Hey Pat, The Rhino box definitely is shorter than what most Rver's were hoping for so we get this question all the time. Switching to a MORryde Cushioned pin box designed with a Rhino box bolt pattern unfortunately won't give you extra…

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…
