I think a bunch of people just read your post and thought, oh boy, that person is going to be sorry they asked.
To answer your first question I purchased the helper bags from a place in Michigan online and installed them myself.
Truck Parts & Trailer Parts - Pickup Truck & Trailer to Semi Truck The store was very helpful and very communicative while the item was on backorder. Here's what it looks like on my Telluride:
Towing package They advertise providing additional support within the spring for up to 1,000 lbs. I don't know about 1,000 lbs but in my experience I haven't experienced the squat/sag that I use to when loaded up.
So onto the part you might regret for asking. I can't tell if you are teasing me or maybe you haven't see the nearly 300 posts on the topic of towing that I've made to this forum.
So I'll just assume that you haven't seen my previous posts.
So here are the basics for my answer:
#1 - Please read this:
If you purchased the Tow Package please read this . . .
#2 - To answer your second question, I wouldn't if I were you. If you are asking me this question then I'm worried you don't know what Kia sold you in that package or your shocks are failing when you are expecting them to work. I don't think that's your fault, I think its Kia's problem for not explaining things correctly. You have softer springs and mechanically adjusted shocks. In other countries that sell the Telluride these are not part of a towing package and even on the
Palisade these are part of the comfort and convenience options that adjust ride height while driving and not called a towing package. In order for these shocks to work you need the springs to be softer so that the shocks can pump up. If you add something that will stiffen the spring then the shocks won't move as freely and then you either risk them failing prematurely or perhaps some other problem getting introduced because you are trying to counteract the very purpose of their existence.
I think this suspension has a very specific benefit to towing in a situation when you already have a mostly balanced and level load it might adjust if things become uneven and start to sway, then it might adjust your ride height. But in all cases when towing you need proper weight management and a level load, these shocks will not address what should be addressed for safety reasons with a weight distribution system, a level hitch and proper cargo management. If I were building a towing package for the Telluride for close to 5,000 lbs, I would look for stiffer springs and shocks not softer ones that might be more expensive replace if used heavily. (I'd also add a proper tow driving mode, but that's a whole other discussion.)
If you have squat or sag when parked with the self-leveling suspension, I'm afraid short of getting rid of the components and replacing them with the standard or finding aftermarket, you won't be able to fix this since that's part of the design when the shocks have had a chance to rest. As far as if the sag goes away when you start driving, I guess that is still up for debate when towing in all situations. If you have passengers and cargo in the rear seats then it may be effective at adjusting ride height for up to so many pounds but you still can't exceed the rear axle weight rating.
