Simple Shock question

[XJLI]

That's what i figured the answer was, but i can't see it having a ton of impact. If you are cruising at 40mph and hit a pothole, the forces going up and down aren't going to be astronomically different between a d60 and a d30.

The only place where you are going to see a ton of compression and extension of shocks is wheeling, and most of the time you are going so slow i don't think it makes a hell of a lot of difference.

the pothole thing doesnt make a difference- what does is when your going fast over over uneven terrain. a D30 with alloys and 33x10.5s is a lot lighter and has MUCH less momentum than a D60 with steel beadlocks and 37" bias rubber.

So getting a shock valved for a ZJ in my 2.5L TJ should be fine, or no?

any shock that is made for a lifted jeep will be fine. the 4.0 and 2.5 are pretty close in weight.
