I just installed my kit last week. I have the all pro
standard leaf pack and have extended icon
shocks. Here is what it looks like all installed. From my leaf pack to frame, I had just a little over 7 inches.
The flip kit plate is .5"
The Timbren bumpstop is 4.75".
That left me with exactly 2" of room before it hits the stops. They aren't super hard, I could squeeze them just a little bit with my hands. From what I have read they do compress down under load. If I had to guess, they are probably going to compress down around 1.5". Which ends up making them about 3.25 when compress, plus the .5" flip plate kit. Overall .75" taller than stock if I had to guess. Which is just a little taller than stock. I haven't noticed any issue with them at all, but I haven't loaded the bed down with weight since I put them on either. This is just my estimates from reading and seeing them in place, etc... I think they are going to be perfect for my setup.
