Proforged and Moog front steering parts. The best stuff money can buy. Everything you need to completely rebuild the suspension on a 4x4 GMT400. I pieced this kit together but ended up selling my truck, need to get rid of this stuff as it's taking up space.
FYI - if you're not familiar with...
You are misinformed. They do make a full line of products for the GMT 400

Proforged makes some real quality steering components. I ran their stuff on my 96 impala SS with great success, the owner of the company was really active on that forum.
I really like the solid tie-rod end sleeves they make...
meh, I had my transmission flushed at 160k, almost at 185k now with no issues. Original trans according to the previous owner (I bought it with 147k miles).
