Re: Just got my 4" lift kit
Sounds like he has mixed up YJ and CJ springs.
CJ springs are 2". YJ springs are 2.5".
They are 'not' interchangeable without a lot of metal fabbing and
changing perches, shackles, etc...
They also have a totally different flex rate and should not be mixed
together. The Jeep will be all over the road with mixed up springs.
You also have to have shackles on both springs or the springs will go
ridged and not flex. When they springs flex, they get longer and
shorter so a shackle is needed for this movement.
Front springs have front shackles, rear springs have rear shackles.

Re: Just got my 4" lift kit
My '81 CJ has two different size springs, it is a safe assumption that
William's '83 also has two different size springs. The real test is to hold
the new springs up to the existing springs and see if they match.

That is strange, I just checked mine and the fronts are 2" and the rears
