Looking at getting a 3" lift kit and came across the Rough Country setup. 3" Front and 2" back... and in the back they give you new "N3 Shocks". But no diff drop kit is included.

I tow a cargo trailer about 50 miles 1 time a week from spring to fall, about 2600lbs total up and down highway hills and I figure the stock rear shocks are going to pre-maturely wear out because of it. But will these N3 Shocks be equipped to handle that amount of towing without getting trashed?

I'm just looking to get the extra 3" for some 285/70 R17s, as the only "off-roading" that i do is in the grass around the yard to maneuver the trailer into position. So a fully blown aftermarket suspension kit is way overkill for what i'm just looking to get out of it.

Thoughts on the Rough Country kit? Maybe look into a different kit?
Thanks all!
