Thank you Ovrrdrive. I think he said it right. It is perfectly safe!!!!

All I know is that I would not trust this set up at all. I wouldn't trust the upper bumpstop to hold the spring, its not very beefy at all, not to mention your rotted frame makes those welds even weaker. And a piece of rubber holding the bottom part of the spring in? Come on.... And I would not spot anyone running this setup on the trail, I like my body the way it is, not broken.

This is the proper way to do this modification for anyone that wants to do this (note the coil buckets):

Thank you!

I'll agree, I wouldn't trust the rubber bumpstop, either. Mine have all gone over the years from bottoming the springs out. So, I had a 2" piece of 2" diameter pipe welded in place of the rubber bumpstop and wound the top of the coil around the upper stop like MattK. Still, dead serious.....you guys are making a mountain out of a mole hill with the compressed spring issue. I've had ridiculous amounts of weight in the back of my 4rnr and twisted, compressed, drooped, and bounced the suspension in every conceivable way in the countryside I live in. Even with rubber stops, the springs are going nowhere. If the rubber stop pops off, it's hooked on to the upper stop......it's not going anywhere. And, the rust? Mine's atleast that rusted. It would take far more repeated force than those springs could apply to knock that metal off.

Thanks for all the support guys. As for the guys who think its unsafe. All I can say is WHATEVER!!!!

I hope, for the sake of God, that when that spring pops out no one is injured. It'll be a lesson learned, just hopefully not a deadly one for you or anyone else.

Ignorance is not bliss, my friend.

Take a coil spring out of a ballpoint pen, compress it between your fingers and let it slip out. See how, when the potential energy of a compressed spring is suddenly released in an uncontrolled manner, the spring shoots off in an unpredictable direction?

That's only a small scale.

The coil spring on a vehicle is designed to hold up the car, or atleast it's portion. Imagine all the stored energy that one of these houses.

Ignorance is not bliss.

DudeBud

i think its scary also and your frame is scary too. you might want to patch it up with some galvanized sign posts to go along with those coils.

I think you made your point about compressed springs and the danger, but I'm telling you you're overly concerned here. I don't know why I'm even engaging the argument. Maybe I just need a good one to vent some pent up energy.

"When" the spring pops out? Ignorance is not bliss? What you don't seem to grock is that it's your ignorance since you seem to be ignoring what the experienced testimonies say. NOT ONE CASE OF ANY INCIDENTS HAS OCCURRED with this mod. Why????? Because IT'S NOT GOING TO!

For your information, in order to even get the coil in between the axle and frame the suspension has to be spread beyond it's normal range which it will never see in any offroad situation. And, look at it and how it's put on. The pig tail is twisted onto to the upper stop. I don't know about MattK or anyone else, but it was not easy getting the coil on there. The only way it will come off the stop is if twists off......which is NOT going to happen.

Sorry, brother, but you have no experience with this modification and therefore no base in which to call ignorance. You're only speculating.

And the hockey puck body lift!

I'll concede the rust issue....and the rubber stop, again. Stop the rust so it doesn't get any worse, but I don't see a problem with it for the moment.

This kind of load, rather the way it's loaded, is not typical for me, but the amount of weight is. I have used the vehicle in this capacity for as long as I've had the coils/Zuk mod. It will be two summers/two years coming. No problems whatsoever. Not one sign of stress fracturing on the frame or coil mounts. I check it on regular basis.

Do you you all know what the word conjecture means?

89silverpu

Yes but this is not math this is logic. You may have had good luck with this so far but I can guarantee that in the long run this set up will fail. I give up. You can do as you wish with your vehicles. Good luck.

Guess I'm wrong then. I must be an idiot or something.

This is like welding new centers onto a rotor for a Rockwell pinion brake setup. It works, for the moment, but.. welding to cast is difficult. (I want to say impossible, but there will be a self proclaimed genious who has a brother who knows someone's friend that has done that with no issues.)

It works for the moment. I say best of luck to you when it fails.

mattk

Your right. They were not easy to install. I had to use a bottle jack between the leafs and the frame and jack it apart as far as I could to get the coils in there. To be honest it was more dangerous spreading them apart to get the coils in there than the mod itself. Also the frame is in great shape. No rust through in this frame. What you see in the pictures is the old undercoating peeling off. That frame is solid. One of the more solid frames than I have seen on most of these trucks. Thanks to all you guys backing me up on this mod!!!!! This mod is not going to fail!!!!

conjecture n. Inference or judgment based on inconclusive or incomplete evidence ; guesswork. A statement, opinion, or conclusion based on guesswork

Obviously the definition has escaped you. The definition and what the word encompasses is not exclusive to mathematics, but also to logic.....incomplete logic in which you are basing your argument on. Experience should tell you that logic often falls short in light of speculation and hard evidence. Where is the evidence that this will fail? I, and others, have plenty of evidence it will not. If were going to, it would have done so by now, I can assure you. As well, you are ignoring mathematical physics that has been explained because of your opinion and bias.

You give up because you cannot sway opinion with arrogance.........what you think you know. I guess I will see you in ten years when this "contraption" is still fully operational.........and still very safe.

thook

You're completely comparing apples to oranges in this situation. Weak. The physics are completely different. And, to you....I say again, where is your evidence?

thook

And, there was silence.....

Finding it difficult to argue? Nice.

mattk

There is no evidence that this will. There are plenty of us with the mod and no failures. Thats all that needs to be said.
