I just have the 2" Calmini on the front of my Pro4X. I ran that alone and it perfectly levels the frame of the truck. The space in the wheel wells will be different though which can make the truck look slightly front high (very, very slight - hardly noticeable except to obsessive compulsive people like myself..LOL). I tow a medium size toy hauler, so I ended up adding air bags to level the truck while towing. So now I just level it with the bags until I get it to look like I want it to look.
But to my original point, I believe the rake on an SV is a little more than the Pro4x and if you just go with the 2" only front blocks, I believe your truck will be very close to level in the wheel wells yet still have a very slight rake. So with the SV, why not just go with the 2" Calmini block set up only as opposed to a 1" level kit?
