Well add a leaf to the front or I think they have 1 inch block for the front wouldn't do anymore than that though depends on what the truck is used for could always lose a leaf in the rear
Dann I'm not making near the progress you are haha I still got headers fuel lines tranny lines radiator/fan
Brackets water pump and all the electrical looks good
As far as power no muffler or or a straight through muffler (baffle less) is the way to go but gonna be loud!
And h/x pipes do score a little more power than true duals I watch alot of engine masters love it all these tests have been done on the dyno
It should kick in whenever you are coasting you don't feel it but it should tell you in the gauge cluster gotta flip through where it says v8 it'll switch to v4 but nothing but problems probably where the oils going
Does it have dod if so thats the numb 1 cause of low oil pressure and oil burning delete the cylinder shutdown there are kits I'm gonna do it when we sell our 08 for a 2014 I refuse to go to the new bodystyle I love this gen
