I just got my 881's and 891's in the mail. Prior to this i installed Monroe shocks in the rear. I now have about 500 miles on them and they are about 2 weeks old. I am going try to get $30 for them from a local Toyota nut. I was told that these shocks would work but certain situations on the dirt would put strain on them. I ended up (after scouring the web) getting a pair of skyjacker nitro. these were $98 with S&H. the front will get a pair of bilsteins but not sure which yet.
I ended up with the coils, front spacer (1.75in), diff drop (do it), skyjackers on the way. I will find out about extending my brake lines but i have heard its unneccessary. i think its a case by case basis.
