FJ Lift options
My first post here as I spend most time on the Rover boards (they need more work on them). I have a 2007 FJ/auto that I purchased new and I have already gone through what you are contemplating.
Stock suspension is great if you want a Corolla... otherwise it needs serious upgrading to be off-road worthy.
Stock shocks and tires are not suitable. I used 285/70 -17 BFG KM2's. I have 33K on them now and they are 1/2 worn. Tracking is great (more on that later) and o/a performance is excellent on and off road. Work well in the snow too! Bit noisy as they get about 20K on them , but it's a mud tire...
I originally used Toytec Bilstein 5100's f&r for about a year w/OME med. springs all around. This provided about a 2.5" lift. Personally, I thought it was a tremendous improvement over stock for about a year - but anything is better than stock. After a year I got tired of the pitching and did a radical change as follows:
All-Pro 2" Fox shocks w/8 way comp. adj. and external reservoirs all around. Kept the OME springs in the rear.
Total Chaos UCA AND stock length LCA's (I thought this might be overkill until I realized how flimsy the stock control arms really are - it'll scare you...)
Man-A-Fre control arms top and bottom in the rear
All Pro has an exclusive valving for their Fox 2.0 shocks so I wouldn't recommend you get those from anyone else - otherwise go 2.5 if you plan on a big bumper/winch. ( I have Lucrum mount w/Warn 9.o rc winch which is light weight).
I also added the All Pro steering kit and sway bar links. I'm not totally pleased with the Steering heim joints as I have one going out now - but the setup is way stouter than stock.
Suspension dialed in perfectly, tracks beautifully and the pitching is totally gone. This so dramatically changed the suspension dynamics that I now fully justify the price - and it's a chunk of change!
I also installed the TRD S/c with the APR X-1 kit. I added the 7th injector, overdrive pulley, JBA shorty headers, URD Y pipe and TRD S/S exh system.
I don't know how much HP (maybe 350-370??) but I can outrun a BMW M series Z1 in any gear anytime I want - by a huge margin! In fact, now I'm going to have to upgrade the valve body in the trans because I'll burn up the trans otherwise ( although I've gotten over having to step up to every race challenge that comes along - but sometimes it's hard not to...)
As I hope you understand - this is NOT an expo vehicle (my 1967 109 Land Rover serves that duty). But as a DD where I can get the best gas available these mods have turned the FJ into a vertiable sports car - I'd say performance wise (handling and engine performance) is almost in the same league as a Porsche Cayenne and that's a very long way away from where it all started.
Ck the Toyota boards and Pirate and read all you can - you can profit from other's mistakes/misgivings. That's what I did and I am very pleased with my results so far. Now I'd like to investigate/invest in changing out the transfer case to a lefty gear drive unit as I am not fond of chain drive units. Yeah, once you start there's no end to it but I really enjoy modding my machines anyway!
Good luck and hope this helps
Cheers!
