I got one and Im trying to find a suspionsion lift for it I've already checked out purenissan.com and they or any body else has one could I modify an Xtera kit  

The front IFS kist will be exactly the same for both the Frontier (any cab configeration) and the xterra. The only difference betwwen the 2 chassis is the rear leaf set up. 4x4 Frontiers employ a leaf over axle set up while Desert Runners (2wd) Frontiers and all xterras use a leaf under axle combo.

I would go with SLR because they built great product, it will take some time to get your order, but it's worthed

I do have a set of 3 inch lift arm for sale.
