i , and most people will know that KONI and BILSTEIN are the ducks nuts!
they don't stick em under big boeings 747 and rally/racecars for nothing!
like you said conditions,usage,car plays a big role in choosing the right shock.
PERSONALLY i have fitted many,many TJM XGS kits and never ever did we have a comeback due to a failing shock!
same with the dobinsons, eversince i have the 4-6 " suspension kit from BIGO4X4 wich has the dobinson springs and shock i cannot fault them! works bloody awesome both on and off the tarmac.
just my 2 cents worth.....
everyone has it's own set up that he likes but like i said, i have seen many fail when it comes to durabilaty.
and for bilstein... i would never use a monotube shock on a 4B!!
and yeah. if you can afford to stick the big KONI'S on it , YES they are the best! and fully rebuildable...
