Interested in your finding, i changed out the lower and have been been putting off the upper, until a tuneInstalling the 600lb top spring today. Will update when complete.
I thought the tender spring is supposed to be compressed. It’s sole job is to apply pressure on the main spring to prevent it from coming loose when it unloads. At least that’s how King explained it to me.
That really doesn’t make sense to me. That tender spring needs to have some available compression or why even have it. There is no way that main spring will be loose when the shock unloads. That spring is always under compression or it would be loose with no load on it. King couldn’t give me a straight answer when I called them with this issue. They recommended changing out the main spring and said it was not a big deal if the tender was fully compressed. I just don’t buy that.
I changed the main spring from stock 350lb to 450lb previously but the stock 500lb tender was still fully compressed. So, that is why I changed to the 600lb tender spring.
Really curious for photos of your front end. Did you run any tuning on your Kings from the business you purchased from? Mine rides like a brick and shops aren’t very helpful and I’m running out of time before Moab. Steering also feels loose after lifting, even with an alignment.
Do you have a part number for the 600lb top spring? Thanks man
i did the same for the lower
I just measured my fronts per your video and I measure about 5-1/2” as well. I have not noticed any roughness or loose feeling you are describing. I am at 15 clicks from soft. I attached a couple pics of how mine are set and how my Bronco is now sitting with the new 450/600lb spring setup with all my stuff in the back.
Side note - Looks like maybe your Resi hose is taking a beating on the control arm
I have had the new 600lb tender springs for a while now. After changing out the main spring I just didn't have the motivation to take them out again and add the new tender. But, I had a free Saturday and finally got it done. The biggest pain in the butt is taking out the wheel liner. I only take out enough of the fasteners to where I can bend it back and get to the top bolts. But that freakin 7mm that is underneath, where the factory slider gets in the way is a royal pain. I have a million ratching box wrenches but I did not have a 7mm so I had to use pliers to get that one bolt out. I just order a 7mm so next time, I will be good to go. Anyway, once you past the liner, the rest is fairly straight forward. I also took the opportunity to install my Borne Off-Road rear shock protectors. I actually had some scrapes on the bottom of my shocks so I wish I would have added those protectors earlier.
Yea, it was rubbing a bit but I ended up just lightly hammering in that angle piece at the top of the shock with a plastic hammer and it moved it out of the way. It is not rubbing any longer. The other side is actually worse! But both are good now.
