Designing a PCK for the 5th Gen, need some input..

Hey guys, I designed a panhard correction kit for the 3rd Gen 4Runners that has proven to be quite beneficial for restoring stock geometry and improving handling after lifting the trucks (- if you're unfamiliar with my kit, check this link and the links included in that thread.)

So now I'm working on a similar kit for the 5th Generation 4Runner, but need some input, since I'm a 3rd gen guy ;)

Specifically, what are the typical lift heights for these trucks (rear specifically)?
2 inch? 3 inch? 4inch? etc.

The donor truck I'm working from has an OME/Bilstein combo and the rear is lifted almost 3.75" (measuring the panhard angle) - is this typical? Should I design for lifts in the 4-5 inch range also?

Thanks in advance for the wisdom & advice!

I’ve seen anywhere from 2.5 to 3.5” lifts as “standard” for 5th gen.

I have a 3.5” Toytec Lift on mine. Interested in what you might be offering.

Thanks!

that's fantastic - I can do both 2.5 and 3.5 on the axle lift bracket alone! terrific.

I was just thinking about this yesterday. I'm interested to see where this goes.

Working on version 2 today:







This has holes at 2.4 and 3.4 inches of lift; the maximum and still clear the crossmember at full flex.

Will update when my print is finished.

Is there a need to make a drop bracket for the frame side also? - the drop bracket would be for leveling the bar if one was running 4.5 to 6" of lift..

?

if there isn't a need, it will certainly help keep the manufacturing costs down.

I really like the design on the 3rd Gen’s. Great idea too. Most of the 2” or 3” springs. I’m running 3, but have no idea what the lift came out to. I’m getting read to make some rear links, so I’m looking forward to seeing how these turn out.

I have no clue about the physics behind this but....

Don't you want to adjust both the frame side and axle side to keep things factory or does it matter?

We have a kit, y’all.





I’m not sure we need to go beyond 4” lift, so unless I hear otherwise, I’ll send this out for quotes first of the week.

Hi Mikey - if you can do it on the axle side only it actually improves the roll center. On the 3rd gen, because of the frame architecture we were limited to a 2” lift on the axle side, so we used a drop on the frame side to level those who used 3 and 4” lifts - with no penalty over stock (since the bar was returned to a neutral height and leveled)

On the 5th gen, we can get up to 3.4” lift on the axle side, which is phenomenal, and actually improves the roll center. Very exciting.

Ok, well call me intrigued and interested since I need one and don't like the idea of an adjustable bar since that is not the correct way to fix the problem in my opinion.

Awesome timing. A few months ago my alignment guy said my axle looked to be 3/4" over to the right. I did some research but it didn't seem like a 2" lift in the rear should throw it off that much. Of course I could have gained a bit more than the intended height. I can physically see a bit more tire right while on level ground though compared to the left. I may consider this if it wouldn't hurt anything. Should only make it better?
