How much travel is gained from going stock to Kings 2.5 Ext coilovers?

Pretty much what the title says; how much travel is gained from going stock factory shocks to kings 2.5 ext coilovers? I read some old threads saying that stock front suspensions gives about 8" of travel. According to Accutune, the extended length of the kings is 22.60", but I'm sure that length is of the shock itself, not the travel that it can provide.

All helpful support would be greatly appreciated, thanks.

 

2nd/3rd gen trucks can, at best, do about 9" up front on stock length arms. CV bind is the component that provides the hard limit first.
