I was scared with 265s the wheel well would look too empty. But your truck looks good! Now to see if Dobinson's can make me something similar to your setup with their struts instead of the 5100s...

It's more than 2" up front. More like 2.5".

I've had my setup for about 3,000 miles so far and I can't say enough good things about these springs. They ride amazing. Feels stock confortability-wise.

Has anyone done the C59-300 / C59-325 setup with Dobinson struts/shocks?

I'm looking for a very mild lift and keeping the ride as close to stock as possible. I am otherwise totally stock and don't ever carry any extra weight. Since the frame is nearly level as it the truck comes from the factory (around 0.25" forward rake) I'd like to keep it as close as possible.

What I don't want is *more* rake than OEM to the front and the Dobinson parts list 1.75" front and 1.75-2" rear.

Does anyone know the spring rates of the coils and increase in spring rate vs stock coils? The PDF spec sheet only suggests coils for application (i.e. if you are adding weight) which is also very beneficial but I like data and numbers!

I'm curious to see how the stock front and rear compare with the Dobinsons mild lift options

Front Coils: C59505 or C59-300
Rear Coils: C59-325

edit:spring rates on first page of this thread...thanks sn_85

Fronts I'm looking at upgrading shocks to 5100's, and either setting front to 1.75" or at 0 and getting Dobinsons coils but want to get rid of the nose dive and improve on/off road handling ($ a bit of a factor here).

Rears I'm looking at the 5100s and was looking at either 1" spacers (not too keen given I've read they might produce undesirable riding characteristics) or Wheelers T13 coil option (12% increase spring rate over stock) but stumbled upon this thread and am now intrigued by the Dobinsons offerings with 35mm (just over 1") or 50mm (just under 2").

I do want to maintain some positive rake similar to factory look as this is loaded on weekends (kids and gear) and occasional towing of utility/camper trailer but don't want to sacrifice ride quality driving around town unloaded.

All this said, I would like to find a setup that is slightly stiffer to eliminate nose dive and improve handling (read: slightly less body bobbing) and be able to drive around town during week without feeling harsh but without compromising the 4Runner's handling while loaded...the latter being more important due to safety considerations with more weight and occupants on highway and backroads.

Sounds like I might be asking too much...?

Dude, spring rates are listed in the very first post...

Yikes, they sure are. Thanks. Not sure how I missed that...

Everyone using either our struts or the 5100's so far has reported back a considerable difference in nose dive, so I think this will solve your problem. I'd only suggest the struts at the 0 setting unless you're specifically looking for a lot of front lift. With everyone running 5100's and our coils, I suggest the 0 setting at first, so that they don't overlift the front end and end up not happy with it. A little too low is better than too high in my opinion on the front end.

I'm running the C59-300/C59-325 w/ their GS59-574/GS59-701. This puts my lift at about 2.75" front (because of the LT front struts that have a perch that sits 1" higher) / 2" rear. I would say my 4runner sits pretty level w/o much rake. (There is a picture in the previous posts). I can't really give you an accurate ride feel contrast between stock and post lift because I'm running some e-load k02s. However, I would say the ride is just a tad bit stiffer than stock.

I am looking for basically the same results from a lift as you – mild overall lift and have a little less than factory rake. I was considering the Dobinson C59-325 coils because I didn't want to lift the rear a whole lot more than 1 inch and I didn't really want to go with spacers. I was told that they were currently not in stock and probably wouldn't get here for quite a while. I ended up ordering a set of the wheelers T-13 coils because I saw a number of posts mentioning that they got around a 1 inch of lift with these coils. Started doing some additional research after ordering them and found even more posts indicating that they got closer to 1.75 in the rear with the T13s. I hope I didn't make the wrong choice on rear coils because I really only wanted to set my front 5100s at 1.75 on the stock coils… I haven't been able to find any pictures of a truck lifted 1.75 in the front on stock coils and the T13's in the rear....

Thanks Mike.

For Mike and the rest of the members, for the rears, if I went with C59-599 rear coils (20mm/0.79" lift) or C59-505 rear coils (35mm/1.38" lift) is it absolutely necessary to get rear shocks? I believe I've seen rigs on the forum running the 1" Cornfed or 1.5" Daystars with stock rear shocks. Or is it a whole other animal with the coil stretching out the shock limiting its ability to function as designed? I'm on tight budget so was thinking if I could upgrade the rears later but get a small lift out of coils for now that would be ideal.

For the fronts, the C59-238 (0.75"-1") option in theory would be a nice compliment if doing the mild 0.79" lift C59-599 in the rear and would essentially be a front/rear lift ratio of 1:1 to maintain factory rake that I'm hoping to keep.

Front coils would likely be paired with 5100's (set at 0) or Dobinsons. Perhaps a novice question, but could I eventually set the Billies at 0.85" with the 0.75"-1" Dobinson front coils to achieve a slightly higher lift...understanding that I would be preloading the spring?

Your rear shocks will pretty much be topped out. Can you do it and have others done it? Sure. It's not ideal and the truck will ride terrible.


I'd personally save up and do it right, the first time. Preloading springs is not ideal either. Lots do it but isn't ideal either.

It's not much of a stretch to buy coils and shocks/struts for well under a grand total from Mike. Skip the coffees for a a few months and save up!

You can check the shock length yourself. Jack the truck up from the hitch and measure the extra couple of inches new coils would lift, then you'll see the lack of length. When shocks top out, it pulls the shocks apart pretty quick, so they won't last as long as usual. But if you were just going to pull them off and throw them away anyway, you could run them for a little while.

People are running 5100's at higher setting with stock coils all the time. Yeah, you can do it, it's just more ideal to use a longer coil if possible. We have a longer travel struts, GS59-574, and it has a coil seat taller than stock, but then because it's also a longer strut, it doesn't preload the coil as much. It's essentially the same as putting the 5100's at 0.85 and gaining a bit more lift. I still recommend the lowest clip setting and the tallest/longest coil possible for the best ride. That's why the C59-448 coils are considered 3" comfort, long coils with a soft spring rate.

starbucks is a great place to see heavily modded 4runners......

Hey

I am also quite intrigued by system but also look to the ARB BP51.
I would like to throw the question in the round if the ARB system is that much better to justify a more than double price.
Main activities would be overlanding, no heavy offroading or racing, but still fast driving through/over bumpy roads.

thx
