Man, you guys all sound like me... Let me clear some things up.

The CALMINI kit does offer increased travel up front.

Think about it. It is physically impossible to make a 3" upper control arm lift kit without creating additional travel.

Try raising the front of a stock Xterra 3 inches by adjusting the torsion bars. You can't, you run out of room before you get the front 3 inches higher.

With the CALMINI kit, the truck sits 3 inches higher than stock, and yet still has an 3/4 - 1 inch of clearance between the droop stop and upper arm.

As for total travel, the SLR lift kit wins, since the Bilstein shocks offer the longest amount of extended travel.

This picture shows that Rancho shocks don't offer enough travel at full droop, it's 3/4" shorter than the Bilstein.
