The springs aren't really bouncy but we hit several bumps in the road and it made me cringe each time. It felt really bad for the jeep not to mention us.

 

Simply measure it. Measure the lower bumps to the upper OE upper bumps cone (the steal cone, not the foam pad) distance, then measure the remainder shock distance of up travel. You will soon know how much bump stop you need to prevent the shocks from collapsing to far. You can always add a 1 or 1.5" hockey puck bumps top on the lower axle side, and remove the TF 2.5" one.

 

I like this idea. I was think the same thing just didn't think of the Puck part.

 

This is true. Unless you are running larger diameter tires than stock, you really don't need to add any bumps stops unless your shocks are too short or you have an amazing amount of flex. The larger the tires, the more bump stop you will need to keep them from stuffing into your fenders.
