That's cool Pro Comp has a lift for the FJ
With the Nissan Titan many owners had issues with the Pro Comp coilovers though, (that came with the stage 2). Can't say they are the same design or not, but I personally wouldn't buy their coilovers.
So most buy the Pro Comp level 1 lift and install either Radflo or DRE coilovers. Don't know if Radflo makes a model for the FJ but ... just peaked at the Donahoe Racing site, and yes

there are DRE coilovers for the 2007 FJ (fits both the 2wd and 4x4 models)... here's a link

These are good up to a 3.5" front lift and are off-road race-quality 2.5" diameter, internal reservoir design.

I run this same basic design on my '04 Titan and I highly recommend the DRE for on-road and off-road use too. They will lift w/o a drop bracket kit, just not as high.
Here's a link to some other DRE products for the FJ.
