To the OP.
I have a 15 Denali sierra crew cab. Just put the RC front level kit 2.5". It's actually makes it 2 3/8" higher on front. Ride is tighter. Had to of course get the alignment.
As for the critics.
It's his truck , his choice.
Why does anybody buy a truck then mod it.
The funniest mod is the CAI.
I'll get one though.
Oh yeah and I have a set of 24" rims going on my denali also.
Cause I can not because it looks cool.
