I'm pretty sure I'm just gonna give it a shot and find out. I'm tempted to just do the RS9000's and a spacer, but seems like the Quicklift may be a better option (warranty/durability). I had 1.5" lift before and that was plenty for what I needed, so even if I do get less it'll be fine. I've got to call Rancho and clarify their promotion, then will probably place the order. I'm just trying to decide if the Quicklift is worth the extra money, really thinking I'll go that route right now though.
I just got the Quicklift's (front) and RS9000's (rear) installed on my '04 4R sport last week. They ride soooooo much better then the old factory shocks. The Quicklifts gave my front a 1-3/4" lift, plus the adjustable ride option is great. The range of adjustability is actually much bigger than I thought, and you can quickly tell the difference. The one thing that I would recommend is getting the spacer for the rear RS9000's. You don't need much. Right now my ride is completetly level, but for some reason it looks like the front is slightly higher (but it isn't). Paid $625 for all four, but I'm getting $200 rebate + $100 Rancho gift card coming back. Let me know if you want to see some pictures of before and after.
