Suspension lift vs suspension travel?

This may sound like a complete noobish and silly question ... but here goes.

Is there a rule of thumb to figure out how much more suspension travel a lift gives you? I'm talking proper suspension lift, obviously, no body lift, BB or blocks.

Are all lift kits designed with this in mind? Let's say I get a 4", I'll get the longer springs (duh), but are the shocks designed to use the extra height as travel? What I wouldn't want, would be to stand 4" taller, with no more suspension travel. That would suck.

Hope this wasn't too messy of a question ....

Short answer... yes. There's a lot of factors that come into play though. If you buy a 4" spring lift, and it comes with 3" (just an example) longer bumpstops, you may have only gained 1" of Upward travel, but you still get the benefits of ~4" of Downward travel. And yes, when you buy shocks for a 4" lift, they shouldn't limit you at all.

Of course, there's always exceptions to this theory. Different lift manufacturers, shock manufacturers, etc.

The primary reason for lifting is usually to get larger tires under the truck. Larger tires are the only way to "lift" the differentials, the lowest point under your Jeep. Spring/suspension lifts raise the whole chassis which helps breakover.

Now the bumpstops control upward travel and all the kits I have seen use them. The shocks limit the downward travel, unless running straps. Good lifts use longer shocks and give you some additional travel. Consider though that for the most part you have moved the stock amount of travel downward by virtue of the longer bumpstops. To really get long travel you need longer suspension arms, and really long travel shocks or coil overs. Hope that makes some sense.
