I hear others state upgrading to 5100s will help with nose dive but its still present.

Anyone know if the 6112 springs are stiffer than stock? I'm having trouble finding stiffer stock height front springs.

I purchased 2020 4Runner off-road premium with KDSS.I also did not like the nose dive and in-fact, I hated it. I upgraded my suspension to Bilstein 6112 (front) and Bilstein 5160 (rear). With this setup the nose dive appears to have reduced considerable compared to stock. I am happy with the ride quality and nose dive.

Of all the trims (including TRD PRO), I feel Limited trim has the least nose dive because of XREAS system.

I have 6112's up front set at the roughly equivalent stock height - there may be less than an inch of "lift" from them in my application.

Overall I feel the truck is more confident in braking with less nose dive. Sure, some is still present under heavy braking, however it's substantially better than it was stock.

It's a plus for me, but the ride is more firm now as a result of the Bilstein's front and rear. I find it a good compromise in terms of handling improvement vs ride quality change.

You have a 6 / 7 year old vehicle, that came with slightly "mushy" / "soft" suspension from the factory. Most of these posts are correct, the Bilstein 5100 will help, but... the rest of your suspension is still 6 / 7 years old.

The Eibach pro truck kit will give you a 1" lift on the rear and 2.75" lift in the front. It will firm up the ride reducing corner roll and brake dive WITHOUT making the ride overly harsh.

Read up on the differences between the Bilstein's and Eibach's (digressive vs progressive). The reader's digest version: Bilstein's are generally considered rougher around town (speed bumps / rough pavement) and better in off-roading extremes. Eibach's are generally considered slightly better around town (speed bumps / rough pavement) and not as good in off-roading extremes. Both work fine for general purpose off-roading.

Either solution is better then the 6 / 7 year old factory suspension if you a trying to firm up the ride.

Let's assume he found a solution, since he posted this in 2014.

I figured I'd revive an old thread than start a new one.

I picked up a 2021 TRD ORP this week and was curious how stiff the springs were in the 6112 kit.

Nose dive keeps my empty seats free of debris and all the stuff in the cargo area neatly stacked against the back seats.

You can order them pre-assembled from 600-700 lbs.

Your comments above are what I needed to read. I had to stop in a hurry today and the nose dive was so bad I started researching my next upgrade!

Same issue on my 17 SR5. Replaced with Bilstein 6112's in front and 5160's in the rear. A little bit better but my family still hates riding in it. 2 of 3 kids get car sick in this thing. Cool 4x4 but not all that practical for daily driver or highway.

Are you still running the original tires? They have really soft sidewalls.

I replaced the tires first, and even with the OEM suspension the new tires significantly improved the ride. At the time i went with Bridgestone Revo 2, p-rated, but any decent AT (if that's what you need) should help. Coopers, Toyos and Falcons are popular here.

I used .5” Cornfed spacers for $50 and problem was instantly gone.

Nose dive… sounds like hard front brake bias. Would also explain reports on this forum of front rotors warping.

if 2 of 3 kids get sick and its due to nose dive.. its a driver issue..

Unless they’re just prone to motion sickness.

Example: I can’t read a book in a car, no matter how good a driver is behind the wheel. I WILL throw up.

Another: Had a Range Rover Evoque with the absolute worst brakes for daily driving new from the factory. They were so touchy and inconsistent it was like unlearning 20 years and 600,000 miles of driving experience.

Traded it for my T4R and couldn’t be happier.
