My own Gen1 '85 T4R currently sits with a moderate lift, yet neither the front nor the rear seems to actually be sagging much:



But all four of the leaf spring packs seem to be pretty much bottomed out and are basically sitting flat on their respective overload springs (during daylight hours tomorrow I will take additional photographs depicting this)...

So even though my '85 T4R does not currently seem to really exhibit any sag, should I nevertheless consider the ZUK mod due to the relatively flat leaf spring packs bottomed out on the overload springs (and for the potentially smoother ride)?

Does anyone ever do the ZUK mod in the front? or only in the rear?

What, if any, are other potential considerations for my moderately lifted '85 T4R with respect to the ZUK mod (versus a stock, non-lifted T4R)?

Finally, I presume I would use the 14" coil spring - but which weight do you recommend?

Thanks in advance!
