2. 5th Wheel Pin Box

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…

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…

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…

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…

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…

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…

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…

Hello Mike, thanks for reaching out. The Curt Air Ride 5th Wheel Pin Box #LC158778 will fit your 2024 Grand Design Influence provided it is currently equipped with the Lippert 1621 or 1621HD pin box. There is no way to look up your camper to know…

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 MORryde Cushioned 5th Wheel Pin Box #MR84VR you were looking at has a total height of 11.35" (pictured below) so you wouldn't see much of a…

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…
