Smarty Jr Vs Sr
#31
Smarty SR.
I been reading all yall have is the auto trans. What about the standard trans. I am in an 08 6.7 with 6 speed standard 4X4. I am thinking of going with the smarty sr and doing the stealth delete. My guess is I will need to update the clutch If I get on it to hard? I just use my truck for towing 5th wheels and travel trailers.
