Hey Rich,
Get the 808 shocks.. (You will be happy)
(4) rear one's.. should cost you about $100 new or I've got some to sell you off my XT8, I had to go back the stock ones, my 808's just couldn’t handle the weight of the Battle truck.. Just a thought..
Happy shopping..
Check out my TX8 build, I explain the how’s and what for’s need for the adjustments.
