coil spring question

ALWAYS HAD LEAFS SO I'M LEARNING. DONT FLAME ME TOO BADLY.

FROM WHAT I HAVE READ, THIS IS UPSIDE DOWN CORRECT? IM TALKING ABOUT THE PLASTIC COLLAR BETWEEN UPPER AND LOWER COIL. HERE IS A PICTURE

Also, WHAT IS THE METAL COLLAR FOR? SOME TYPE OF "BUMP STOP"??.

Re: coilover question

Meant Coilover Not spring

The thing between the two springs is a dual rate slider. Lot of folks say to turn them upside down like they are in that picture, that they are stronger. This is ok to do if your lower spring is as long or longer than the shock travel. I left it right side up on my shocks, just because I don't ever think I'll have an issue out of it like that, if I do, I'll be the guinnea pig and post about it.

The metal collar is a dual rate stop ring. It's designed to catch the dual rate slider on uptravel so the lower (heavier) spring kicks in, slowing the rate and providing stability. General rule of thumb from what I've gathered on an average crawler is to set your dual rate stop ring roughly between 1-2" above your dual rate slider, at static ride height. When you hear static ride height, that means when the rig is sitting level on all fours. There will be different opinions on that, I'm sure. But it all comes down to personal preference. I would start by setting it like that, try it, if it's too stiff over bumps or doesn't allow enough up travel, play with it some adjusting it up a little higher. Also for that rule of thumb to play, your spring rates should be right for the rig, before trying to dial in the dual rate slider stop ring.

You need to spend the time and read all you can through the Coilover Bible on Pirate (links below). Best source of info on the web for learing coilover tech. Takes a while to read through, but you should be able to answer just about any question you have by referring to those write-ups. If not, report back and we'll try and help you.

Also note, the orientation of the dual rate slider depends on how far down you have to run your dual rate slider stop ring. It's "longer" one way than it is the other.

Those look like some really heavy springs, are you aware of their spring rates? And what are the specs of the rig they are going on?

THANKS FOR INFO AND LINKS.

THEY ARE ON A 1 TON YJ REAR. 42"Tires. No IDEA ON RATE. I HAVE WHEELED ONCE WITH THEM AND I THOUGHT THEY WERE AMAZING. BUT, I COME FROM LEAFS SO ANYTHING SEEMS ALOT DIFFERENT.

SAME ONES (ATLEAST APPEARANCE WISE) ON THE FRONT. REMOTE RES IS THE MAIN DIFFERENCE.

I HAD A "POPPING" NOISE THAT PROMPTED ME TO REMOVE THESE. NOTICED THE FRONT ONES HAVE THE SLIDER FACING UPWARDS AND ASSUMED THAT WAS THE NOISE. WHEN TAKING THEM OFF I NOTICED THE NOISE IS FROM THEM HITTING FRAME RAIL AT MAX FLEX. THE ARE ANGLED SLIGHTLY INWARD SO MAYBE MOVING THEM OUT A LITTLE WILL CURE IT. THEY ONLY HIT SOMETIMES AND THEN I GET THE POP.

Re:

Good, if you were satisfied with them from the run you've already made on them, I wouldn't change a thing until you are not satisfied with them.
