TRD PRO vs TRD Offroad factory suspension components

Hi community! So we recently purchased a 2018 4Runner TRD Offroad. The dealer upgraded it to included the black and red 17” TRD PRO rims with a set of 265/70r17 KO2 tires. I found out later it has KDSS so Toyota won’t upgrade it with the full TRD PRO suspension/skid plate package. This is a bummer because that is the stance/height we want for it. So now we are looking to “mimic” the TRD PRO Factory suspension setup with the aftermarket. So far we have decided to go with Bilstein 6112s up front and 5160s in the rear.

A few questions:

What heights should we set these to to mimic the PRO’s height and stance? Answers on google have ranged from .5” to 2” for the front and 0” to 1” in the rear.

Does the PRO have different UCAs than the Offroad?

Is the PRO’s front differential dropped for the different suspension height?

Is there a good front skid plate that fits the KDSS 4Runner?

Thank you in advance for any info!

 

Answers under each question and in bold

 

Looks like like @MeefZah has this covered.

Keep in mind that the settings on the 6112 are different for KDSS equipped vehicles. I am on the 2nd or 3rd notch and gained 2.3"

Here's some information:



This isn't consistent with my 2.3" because I have the +150-200# setup which has different settings.

No

No

Budbuilt, RSG, RCI have option for KDSS, among others I'm sure. I know know @SOS CONCEPTS is working on one as well.


KDSS is actually an advantage at stock height or with small lift. It gives the suspension the ability to flex without fighting the sway bars, so you're more planted in off camber situations.

With extended or long travel, they will eventually limit travel just like a regular sway bar. In this situation, most people will get rid of the sway bars altogether anyway.

 

Thank you all for the info!

 

In case this hasn't been clarified, the rear springs on the pro are the exact same as the rest. So if you insist on "factory pro" stance, keep your rear springs.

 

Question about front wheel camber/alignment On the PRO. If all Toyota is doing is a 1” level with the same UCAs and no diff drop, how are they keeping the front tires on camber?

 

A diff drop would not affect camber. You can lift a 4runner around 2.5 - 3" and still get alignment in spec with stock UCA's.

 

Don't the front diff shaft pull the wheels in as the diff goes up with the vehicle?

 

no

 

The alignment can be adjusted to compensate for different ride height.

The CV axles move with the suspension components. They do not affect alignment. At higher lift, the CV angle increases and can cause premature wear.

 

Ok thanks, I’m more of solid front axle guy in terms of understanding the suspension geometry. My other rig is a Power Wagon. The wife and I just want to do as much as possible to maintain factory geometry.

 

You'll have no problem with a small lift. Just get the alignment done after lifting. It's not a bad idea to wait a bit for the suspension to settle a bit before doing the alignment. If you go higher, you can use aftermarket UCA's to get the range of adjustment needed.

Any pics of the power wagon?

 

Yes, it’s no AEV or Carli monster. I have kept the suspension stock and upgraded the tires to 35s. Upgrading the ball joints, track bar, tie rod, and drag link.

We pretty much go wheeling every weekend. The Power Wagon continues to surprise me on some of the stuff I have climbed through in it for it’s size.

 

Nice! How do you like those Mickey Thompsons? I looked at those, and the ATZ's.

 

Honestly I am really impressed with them. I ran KO2s for years on my previous rig because I was hesitant to run a M/T. The Baja MTZP3 tires are not obnoxiously loud or rough on road and they are very grippy off road on steep inclines.
