Video Transcript for Review of CURT 5th Wheel Pin Box - Helux Shock Absorbing 5th Wheel Pin Box - C73RJ

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look together at this Curt Helux Shock-Absorbing Fifth Wheel Pin Box. The coil spring shock absorption system on this Helux pin box is designed to reduce chucking and jarring when towing your fifth wheel trailer. So if your current setup is giving you a rough ride, especially over bumps or dips, this upgrade can make a noticeable difference in your ride quality. Now this will fit Lippert Rhino Pin Box bolt patterns.

And this is approved for use on Lippard RV frames, which means you're gonna get a smoother ride without risking your trailer's warranty, like with some aftermarket pin boxes. I do want to point out that this is not going to be compatible with offset fifth wheel hitches, just so you're aware of that. And installation is going to be pretty straightforward. This does include mounting hardware, as you can see here. I have it loosely run through our bolt holes here.

So hardware is included. So even though this is gonna be a relatively simple installation, I do wanna make you aware of the fact that this is heavy. I needed help to get it up here on my tabletop. This weighs about 165 pounds, so you do wanna make sure that you have plenty of support when you are lifting this into place. So this does have a gross towing weight of 24,000 pounds, and a maximum pin weight of 5,400 pounds, and a minimum pin weight of 2,860 pounds.

So this is made for larger fifth wheel trailers. So if you are hauling something substantial, this pin box is definitely going to be up to that task. Now this is built for longevity, the Helux pin box boasts a virtually maintenance free design, as you can see. So you're not gonna have to worry about refilling airbags. Another plus is you're not gonna have to worry about a break-in period.

This is gonna be ready to go right out of the box. The automotive grade coil spring is going to give you consistent, reliable performance, while the rugged steel construction with this really great black powder coat finish is gonna do a great job of resisting wear and corrosion. I'm really impressed with the finish, actually. I think it's gonna really look great on your trailer. So if you tow a large fifth wheel trailer regularly and you want a smoother, quieter, more comfortable ride, reducing those forward and backward jolts, and at the same time you wanna reduce long-term stress on your RV or tow vehicle, this is really going to be a great option for you to consider. We do have other pin weight capacities, whether you're looking for a lower pin weight or higher pin weight, we do have those other capacities available from CURT here at etrailer.com. So if you are looking for something a little bit different with the pin weight, you can look for those options here. If you do decide though that this is going to be the one that's gonna work best for you, we would love to hear your experience regarding installation and the operation of this pin box. And you can do that a number of different ways. You can drop a comment on this product page, or you can also drop a review on this product page. And if you leave a review, you can send us some photos as well with this in operation with your towing setup. We'd love to see it. Well, I think that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

I received this curt helux pin box very quickly. I was impressed with how fast and how the shipment was handled. I've installed the pin box but haven't yet towed our 5th wheel yet. 1st camping trip later this month possibly. Maine weather needs to be a bit nicer. Anyway. So far very impressed with the product.
