Hi Jody, thanks for including your CAT scale pin weight. That makes it much easier to point you in the right direction. Based on your loaded pin weight of 2,550 pounds, you need the CURT Helux Shock Absorbing 5th Wheel Pin Box, part # C85MJ. It's designed for loaded pin weights between 2,378 and 2,722 pounds, which puts your trailer right in the sweet spot. It's the best option for your 2024 Forest River Arctic Wolf 3770 with the factory Lippert Rhino pin box because your loaded pin weight falls right in the middle of its recommended operating range.

One of the things I really like about the Helux is that it's completely maintenance free. The internal coil spring does a great job of soaking up road shock and reducing chucking without having to worry about airbags, bearings, or bushings. It's also approved for Lippert frames, so you don't have to worry about affecting your trailer's frame warranty. Overall, it's a really nice upgrade if you're looking for a smoother towing experience.

What kind of trips do you and your Arctic Wolf enjoy the most? Are you mostly taking shorter weekend trips, or do you get out on longer adventures?
