Ok so here is te deal, I have everything to do the RUF swap, hi steer, boomerang shacks,drop hanger,etc, and the lift that my truck had on it was a pro comp 4 in lift with block in the rear, but I took my front leafs off and they match up with my front leafs eye to eye, but obviously the mount point is different. But my question is that my rear leafs have the numbers R-35340-a, I know the (R) means right but are these stock rear leafs or are these aftermarket rear leafs. Does anybody else's have numbers on them?

 

They probably aren't stock leaves. They could be stock replacements.

 

i know this a old thread but mine are the same i would like to know also
