For the front you would use the 5100 series. The back is a little trickier, have you lifted the truck at all? If not, the 5100 will be the best bet because they are a bolt in swap. If you have lifted the truck, you will need the 5125's in the rear because they are longer. The issue with the 5125 series is diameter of the mounting eyes on either end are to big for the frontier bolts. You'll have to make a spacer to step them down to match the diamtere of the stock bolts. I hope that makes sense. If not let me know.

thanks for replying guys. i actually found the part numbers on the prg site.
yes the 5125s bushings are different front the stock one but they can be changed.
i got hold of the 5125 series today and was supposed to match it with my 2''AALs but upon inspection, they are firmer than the stock ones. my question now is will these really ride better than my stock shocks with deavers ? am running 285s by the way.
