How do I fix the nose-dive?

I'd like to rectify the nose-lifting on acceleration, and nose-diving on braking on my SR5.

What's the best way to do this?

I do not off-road, I do not want to lift, or level, or change tires ... nuttin' but simply fix the stupid hobby-horsing.

Thoughts?

Yea, unless you overhaul the suspension, you're going to just have to deal with it. You can fix body roll w/ stiffer swaybars, but there isn't anything for pitch... maybe Xreas?

I took my SR5 up a rough-as-**** dirt road that is around 9 miles long up to dolly sods over the weekend. I was soooo grateful for the nice plush suspension for that drive. :)

The only place the pitching really bothers me is when I'm fitting the 4Runner in my slightly tight garage.
 
I would just add a spacer or get some better springs up front. With the stock setup, the springs will sooner or later become weaker, and the issues you have will be worse I think. I would check out the Eibach springs Toytec has, will raise the front 1.6". The rear of the 4runner's is usually around 2" so the front should still be a little lower. After a while the springs will start to sag I'm sure and the amount of lift will be less then 1.6". Just call up Toytec or Wheelersoffroad and see what they can offer you.

Icon coilovers.
 
Wait and see how the Bilstein 5100 adjustable shocks work out for the people that said they were gonna try 'em on their T4R's.

Who knows, you just might like what you hear and see!

I went with the Bilstein 5100's... They certainly helped the dive, but didnt get rid of it.

It doesnt sound like you want to go through the trouble of installing new suspension, but I doubt there is any other way to help the problem.

lol, yea. he wants to change the suspension without changing the suspension.:shrug:

I want my 4r to be faster. I don't wanna have to buy anything, just make it faster. I just want to run high 9's low 10's in the quarter. Any suggestions?

Thanks!

Well, find a nice Cat. 5 hurricane, and go WITH the wind :) This will only solve the problem short term :moon:
 
well here is what harper said about the icon suspension

"I finally installed my Icon suspension yesterday .Rides like a dream as I just drove it a couple of hundred miles today.I couldn't imagine it to feel any better.Hard to describe,it just floats thru bumps but is still firm on handling. No more brake dive or front end lifting up when flooring it from a standstill like before."


have asked him if it handles better on road compared to xreas...still awaiting his answer...sounds like it does

An expensive fix for a minor annoyance, IMO.* I'd love the Icon suspension, but it is a lot of cash.

*This is assuming you have no other want/need for an upgraded suspension.

Dang Philsey! .......You don't have alot of choices since"I do not off-road, I do not want to lift, or level, or change tires" There is no magic button and there are no suspension gods to pray to that I know of.:roadkill:

You can have custom springs made that give the same ride height but are stiffer and buy some Bilstein shocks to go with them. This will cost you alot of money to have the springs made.

You can put in the suspension from a TE or X-Reas susp.from a Limited. They are or will be going dirt cheap when people upgrade to aftermarket and they are an upgrade to the SR5.

The X-Reas suspension and stiffer sidewalled tires would make a big improvement.I had those 265/70/17 Bridgestone Duelers on my truck for a week when I first got it and to me they seemed real bouncy compared to the stiffer 20's that my Limited came with. Like when going over bridges,first thing I noticed about them.

And for T4Funs question ,the Icon handles better on and offroad then X-Reas hands down but nothing like a BMW or G37 that you mentioned. The Laws of physics and the design of the truck vs. the design of a sports car are at work there. It handles pretty darn good for a +5000lb full framed truck with almost a foot of clearance that it is though.

Lift it or level it Phil!! The Toytec Ultimate kits get great reviews and would be a huge improvement over stock and are cheaper then Icons . Overland Warehouse has just come out with a new 2.0 suspension that uses highly rated Radflo shocks that look real sweet.These are designed by people who know 4Runner suspensions and drive them.
 
Now that's what I'm lookin' for!!

Harper, thanks for the considerate and well thought-out suggestions. In my mind I'm thinking/hoping some kind of shock upgrade would be the answer.

Easy...






Just start stripping the vehicle of everything you don't need to make it go, and I mean everything!
 
new to this ballgame on suspensions. but are all suspensions that expensive as the icon stage 5? Over $4k! come on, who could afford that? Is it really all that compared to xreas? I want more of a sport tuned suspension. any kits out there for 4runner?

Not all suspensions are that expensive...but good coilovers for any application are going to be pricey. There are a ton of machining hours that go in to them, along with all the regular suspension bits (valves, springs, oil, bolts, etc). Xreas is a cheaper solution, with more parts, trying to accomplish the same thing as a decent coilover system. If you cost in the stock suspension plus all the Xreas parts from Toyota guaranteed it will be the same if not more than a good coilover suspension. The other good thing about an Icon (or similar) setup is the weight savings over stock steel suspension...you may only be saving a few pounds, but all of them count.

I went ahead with it...wasn't that much of a cost to improve the ride and capability. This is where I would spend my money first, above other mods. I find that most people who get into truck suspension start with spacers and learn that it isn't all that. Then they improve springs and shocks and notice a diference. A coilover system takes it one step further...closer to buttery stiffness and pure fun!
