It is different then stock but not what I want for my power levels. I will get the steel 2 piece. Helps eliminate vibration, fully adjustable for lowering or lift, smaller diameter, and more then handle the power.
A company out of Cali called Performance Driveline makes 2 peice set-ups, but recommended 5" dia x .125 aluminum wall for my application, if if will fit. Getting tranny and rear end rebuilt soon, cam and heads right after. I'm told I will likely be at the limit for my motor at that point.
I'm running a 2/4 that measured out 3/5, hope that helps . I think the black wheel well trim can throw off the drop visually too, so mine are painted. One other thing I considered, I'm 6'5", so I didn't want to feel like I was crawling up to get out of the truck.
I did both a couple of years ago and it was like night and day. I can't wait to get my truck back after dropping it, I'm expecting even better handling.
