Video Transcript for Hellwig Pro Series Helper Springs Review

Hi everyone. Aiden here at Etrailer. Today we're gonna be taking a look at the line of Hellwig Pro Series Helper Springs. This is gonna be a great solution to help enhance your suspension and help protect the factory suspension on your truck. Let's check it out. Now, the first thing to know is that these come in a variety of different shapes and sizes.

The ones in my hand are not the exact same as the ones installed on the truck behind me. So what you wanna do is take your vehicle information and plug it into our fit guide. Your year, make, model, will have a set of these that work for it, and that's the one you wanna pick up. So you can find the right one for you and your truck and they all install about the same way. I mean, it's the same idea where you've got U-bolts attaching this to your leaf springs, and for the most part, they will function the exact same way too.

So the idea behind these springs is that they become a maintenance free enhancement for your suspension, allowing you to get more support on maybe some bumpier, heavier loads and still let your truck ride at a normal ride height and bring it back to that factory ride height quicker. Rather than maybe hitting a big bump with a heavy trailer and your truck and trailer taking a long time to correct before again, you've just hit another bump. So it's gonna smooth out the ride quality, hopefully bring you out a little bit more level and do things like align your headlights and improve the contact that your front tires are making on the ground because we're sagging less. Now because these work in tandem with your factory leaf springs, it's also going to help reduce the stress on those, helping your factory suspension components last a little bit longer and not having them flex near as much because they have those helper springs, helping them out and reducing the amount that they have to work. And they are somewhat adjustable.

And what I mean by that is during the initial install process, there's gonna be some outer U-bolts that you tighten down a certain amount, tighten them down more, and you're gonna apply more preload, essentially causing these to engage a bit quicker and helping out with those heavier loads a bit quicker. Don't thread them in as much and you're not gonna feel it as much. It's gonna be more true to factory ride quality and better for the lighter loads. We've got ours set right in the middle right now, so after continued use we can re-evaluate and see what we need to do, but chances are you're gonna set it and maybe change it once to fit your needs a bit better after towing with it for a little bit and probably just leave it there. This isn't like an airbag where you've got that on demand filling or letting out air pressure to accommodate for a wide range of different trailers.

This is for your one trailer and truck combination that you can set and really dial it in because with an option like a sumo spring or a timber in, you're stuck with just that one setting. And if it doesn't quite work for your truck and trailer combination, you're gonna find yourself in a pinch where it just doesn't work super well. Whereas with this, if it doesn't work out of the gate as we want it, we can adjust it a bit and fine tune it from there. And that'll do it for our look at the line of Hellwig Pro Series Helper Springs. Thanks for watching.

Easy enough to install but the kit needs locknuts! Also a better example of how to adjust properly!



by:

Directions not the best got very confused putting it on watched a lot of you tube videos they were not that good either. I did have problems with my nuts stripping on the foward u-bolts on both sides fwd of the axle. I did torque the nuts with a calibrated torque wrench. Not sure if it was caused by me or the poor directions. Reached out to the manufacturer he said never heard of that before and said he would send new hardware. I am out of state in a rv park will see what happens when I reinstall. Oh had to cut it off in a Safeway parking lot on my way to TX
