Contact Greg at PRG (and have some patience, he recently celebrated the birth of his first child, but was working through some complications at the hospital), he offers an excellent variety of Xterra specific parts that are high quality and install well.

He is also very good with his customer service and follow up. I installed (solo) one of his spacer and shackle lifts that enabled me to run 285's and enjoy a wider footprint. I have used this lift for about 7 months with no issues, and am now looking to upgrade to the 3" coilovers, UCA's, and probably and Alcan leaf pack for the rear. I really wanted to increase the X's ground clearance inexpensively, but now realize that my off road passion has expanded and I need a little more lift and flex to support the weight of the future.
One of the things I learned from this site also was to consider the weight of your protection (front and rear bumper upgrades, and skid plates and sliders) which will need to factored into the spring rates for both front and rear.
You can also go to Clubxterra.org and go to the generation one forums (click here>>>>
http://first.thexterra.org/forum/? for more input and advice on suspension components.
Good luck and happy modding!
