I love it. But also be aware of my post on FOX's page regarding the maintenance.

Not only was it a birthday gift
Birthday gift for a Raptor owner?, but I had it installed Friday night at the TRR earlier this year. Friday, my friends and I drove the course with the truck stock. Saturday we drove it with the stage 4. Unbelievable! I noticed an instant difference just on the ride back to camp on the ranch road. The suspension really sucks up everything in the road.
As you know, the rear shocks are adjustable and you can easily adjust them yourself with an allen wrench and a 9/16" box end wrench. Just a 1/2 turn and you can feel a difference. On the rear, there are three tuning bypass ports. Two for upward travel and one for rebound. You only have to adjust two of them to set it how you like it. Corey can recommend a tuning based on what you hold in your truck bed and what kind of driver you are. I have mine set up for road / highway travel for now. But can change it for some off road fun if I need to. Or just set it and forget it. I never thought I'd jump my raptor, but with the stage 4, there is no worries and it really gives you the confidence to put the foot on the pedal and have a bit of fun.
Are you thinking of also going with the Tie rods and UCA? Do you have stock wheels or aftermarket? Larger tires? If you keep going, you will eventually be changing out your front drive shafts too...
Also, waiting for Hock to chime in. He has considered these upgrades too and has a very knowlegeable stand point.
