Anybody have any pics or info on what stock springs should look like in terms of arc? Truck is totally stock. Ride feels pretty good, but I could just be used to it.
 
The stock height of a FJ60 is 69.5" according to this thread.

If the are the orginally springs, mostly likely they do not have near the arch they did when they were new.

It just depends if you want to spend the money and what you use the truck to do. But a new set of lifted springs is a big improvement.

What point on the truck is height measured at? The very top of the roof?
 
Presumably the highest point in the roof, makes it damned hard to accurately measure. Anyone have a more practical point to measure and what that height should be? It would be nice (maybe not) to know how much sag we're dealing with.
 
it says you have 20+ year old springs and they've given their all to the party.

that's to say, it's not that they will just break any minute. the ride and handling just gets worse and worse. upgrading will help bring the vehicle into originally designed tolerances for these things.

i'm going with new suspension this spring when i've payed off some other debt. can't wait either.
