$20 it is! The guy seems chill and is fairly local so it makes it easier anyway. Now just need 5100s to become available.

Has anyone tried using Fox 2.0 shocks instead of 5100s?

If you haven't pulled the trigger yet, I'm glad I went with the 1.75 setting over the .85. No issues with UCAs or alignment, just some minor fender lining rub in the front. Easy fix w/ a heat gun. Also removed mud flaps and running boards. Picked up some General Grabber ATX 265/70/17 last week and love the look and results. MPG is down slightly but still averaging about 18-19 MPG per tank. The only thing I would have done differently is a 1.5" rear spacer instead of a 1".

I recently picked up springs from a 2010 FJ. The fronts were still assembled so I rented a spring compressor and took them them apart today. It appears one of the front springs (left) has more coils than the other (right). I count 8 coils versus 7. I assume the longer sprint helps correct the drivers side lean. Does this mean I won’t need a spacer? My trucks a V8. Thanks!

Yup, got that. Wondering if with the heavier V8 if I’ll still need a spacer to correct drivers side lean?

You have to figure that the extra weight will effect both sides equally. IIRC the driver-side spring has a slightly higher rate then the passenger side. I think you'll just see a lower amount of total lift then if you had a v6. I could be wrong though but I wouldn't add a spacer just to the driver side.
Ugh, I really need to get off my ass and get this done. Have had the FJ springs sitting in the garage for close to 8 months now. Going to do 5100s and planning on getting new tires for the winter.
Pretty torn on 265/70/17 vs 285/70/17. Really sucks that the 285 doesn't fit in the spare spot. If I were to go with 285s I'd keep the stock spare and just have to shuffle it to one of the front wheels in case of a flat.
Right now leaning toward FJ+5100 all around, 1" or 1.5" spacers for the rear to maintain the rake and 265/70/17 KO2s.

My FJ suspension were 08/09 Trail Team coil & Shocks. These were direct bolt on. No modifications what so ever. I got them new. You can read about it on my thread. It’s pretty pedestrian compare to the amazing members here.

I've been toying with the idea of going up a setting on my 5100s, from 'stock' to the .85" setting. I have front FJ springs already (gained about an inch of lift) but I wanted to see if other members w/ FJ springs set to the .85" setting needed aftermarket UCA or a diff drop...? Also, any current ground-to-fender or hub-to-fender measurements would be great.

I did the FJ springs set at .85 with no diff drop or UCA and everything is good. The CV angles are pretty much level now. Not sure on measurements though. Tires are 265/70/17s as well.

Cool thanks for the reply. Is your 4Runner a V6 or V8?
Looks just about where I'd like to be.

Mines a V8. I was actually expecting a bit more height on the front but I think the extra weight of the V8 is bringing it down a bit.

Gotcha - Yea, I'm thinking since mine is a V6, I might have to add rear FJ springs for a little extra bump if I jump to the .85" setting. Right now my rear springs are stock, I just swapped out the shocks.

You can run any coils you like if the look and ride is to your satisfaction. For example, I have 2015 Tacoma TRD Offroad coils on the front and FJ coils on the rear. See the suspension post linked in my sig to see a side-by-side pic of the FJ rear springs vs. stock and you'll see why many people swap them out.
Personally, I think many people overlook the need to change out the stock springs period regardless of what they're replaced with. They're made of stout metal, but the youngest 4th gen is 11 years old now and likely has 100+K miles. So no matter how stout, I think it's safe to assume that metal which has hauled around a 4500 lb. SUV for that long and that far probably isn't performing as well as it once did. People always go on about shocks, and they're important, but springs are just as important if not more so.

Curious as to why FJ springs are being used in the front of 4th gen Runners especially with V-8's and 5100's. The 5100's will allow you to raise ride height, and the FJ are all V-6's so wouldn't those springs have less load rating than the factory 4Runner V-8 Springs?
Are the rear FJ springs load rated higher or just generally longer than stock 4runner springs? Thanks

From my understanding the FJ springs have a higher spring rating. I did the 5100/FJ swap (leaving the perch on the bottom setting) and netted exactly 1" of lift with my v6. I plan on moving the perch up one spot to the .85" setting in the near future however.
