Put them on (2" Billit aluminum) a few years ago.Noticeable improvement in cornering and ride. Also eliminated people from telling me I was offtracking when they were following.
One of the best improvements for the money I have done for the truck. I retorqued them once and have never had a problem. Hope this is helpful.
