As for SPOA lifts you must first start with the most important item in the kit, the spring perch. Only use spring perches that are welded all the way around on the axle housing to distrubute spots and it will eventually collapse the thin Samurai axle tubing. Here are pic's of the perches Trail Tough and Aftermarket4X4 [img]images/graemlins/grin.gif[/img] sell.
Stay away from "bolt-on" SPOA kits and perches that weld only to the lower perches and those that weld on top of the U-bolt retainers on the front axle.
The next most important item is steering components. The best byfar is the crossover steering systems, but are very pricey so alot of people go with the 3" drop pittman arm (since there is no core charge) or the 5" drop Z-LINK:
Next you need to use 20" - 24" long RUBBER brake hoses. Stainless steel braided lines look nice, but I have had people snap them on the trails since they do not stretch like the rubber. Loss of brakes is BAD!
You should also use either 1 inch driveshaft spacers (one front and one rear), or 1" extended slip yokes, or 1" extended driveshafts.
For shocks I highly recommend the Doeschtech's for a really nice ride and excellent performance off-road....as well as for the built-in bump stops. If you are building a vehicle for maximum flex then I recommend installing new upper and lower shock mounts so longer shocks can be used properly.
The BEST piece of information is to buy a COMPLETE KIT (don't piece it together from several different manufacturers sice quality lift kits are designed to work as a system) from a company that is 100% there for their customer at the time of the sale and willing to answer your questions in a second after the sale.
