Yeah and the frame needs a bit of re-work to add a proper coil bucket that would have real strength and sufficient height for coil-overs (longer than the stock shocks). Assuming the upper control arm mounts have sufficient spacing for said coil-over, etc, etc.

This is an "idea" but it's a ways from a "design" in my opinion when it comes to feasibility and cost.
All I see is pictures with someones logo photoshopped out from an unrelated project.

Show me a prototype that functions and I'll start to get interested, until then this gets filed away with all the 'cheap easy SAS' threads.

So are you interested or not Andy? :hillbilly: Gosh engineers take away all the fun!
 
I wanna watch someone else first.

I'd probably rather SAS the 100 and LT the Tacoma, that sounds like fun right, 30k of upgrades for 15k worth of trucks?

Really I may one day SAS the taco and that will be about it, I'm no fun at all.
 
I think a lower control arm that moves the front wheel forward enough to
Clear 37s with some body clearancing and fender trimming is where it's at.

If something doesn't show up soon I'm going to have a race shop I know well make them for me.

Now if only there were 5.29s...

What diff would you run? I'm thinking the 100 diff would not last too long against 37's and long travel. That said, there must be Tundras set up as you describe, I wonder what they run for a front diff?

I'd run the ARB front that I have now. I ran 38.5 on my 85 4Runner and did not have a problem so my limited knowledge of the 100 makes me think it should be fine with my gentle skinny pedal use.

I'm sorry but did you even read my comments at the beginning? This thread is a discussion about the interest level on this type of suspension. I have already gotten a ton of impute about the direction it would need to go. Looks like most want a much cheaper and less high speed performance orientated design. According to your comments I should have spend my time and money to develop a working prototype that no one wants to buy before I got any impute. That photoshopped suspension system is for a 4wd Ford Raptor. The similarities in design and application for the 100 Series should be pretty obvious.

Yep, read, understood, and filled away with the 'cheap easy SAS' threads. I just think it's an incomplete idea with a lot of unpleasant surprises ahead. I hope it works out great I just don't see that enough homework has been done yet that you can even think about price or make statements about no frame mods. I hope I'm wrong, have a nice thread.

Have you built a working design in CAD Solidworks of any other modeling design from the manufactures specs and tested the frame and suspension? If so please explain why the frame is inadequate for a suspension design that is well yet to be determined? If not then you are just spouting your untested, unverified opinion on a design that is unknown. Here's an idea why don't you be open minded and help the design over come some possible obstacles? If you have some experience and back ground in design, modeling and stress loads then share it. Why in the hell would you offer nothing to the thread and yet expect everything done and completed for you to judge and pick apart like some Monday morning quarterback is beyond me.

The company I would be working with builds everything in 3D CAD (Solidworks) before it goes into any production so it can be tested for geometry, fitment, stress or any issues that might occur before the part is put to use. Frame issues (if any) would be address during this process. Here's the deal guys, this s*** costs time and money to do. If there is no interest in the type of suspension system then this project is done. I knew there would be times when this thread would get off track. I am here to get it pointed back in the right direction.
 
Do your homework, drop the attacks. I have done solidworks models of suspension systems from scratch and the built the frame and the a-arms, but that is totally irrelevant here.

I already pointed out that there is nowhere on the frame to attach the upper coil and not a lot of room between the upper frame mounts for a coil. This has been discussed in other threads (search out the russian coilover conversions). But you're not going to modify the frame so I think you've painted yourself into a corner already. You're making travel claims based on what was achieved on a raptor but have you compared the stock arm lenths between the 100 and the raptor? I have not but I'm guessing the raptors arms were longer to start with. What about the camber curve, will it stay in an acceptable range using the stock arm mounts for a 12" travel system? What do you think an accpetable range would be.

There, have some tech, drop the chat and personal crap. I'm trying to leave your thread alone but after your last post I just had to keep it going. If you wanted to stay on track you would bring the tech not the mud.
 
I for one, don't want my vehicle to be 10 inches wider up front. Raptor track is 73.60, Land Cruiser is 63.80. Don't get me wrong I would like to have more travel up front, but if you want a long travel front you will probably end up with something like this.

These are all valid concerns that would need to be addressed when speaking with the fabricator. There would need to be a coil tower mount. I am hopping a tube upper arm can be made to fit using a single coil over while still utilizing the stock mounts. If not then other options will need to be looked at. Yes the upper and lower arms will need to be lengthen in order to achieve more travel. There really is no other way to accomplish more wheel travel travel other then completely reworking the front end mounting points. I think for most on here this would spell the end to this lift kit. There will be some compromises that may not work for all. What I am trying to get is an interest level (which so far has not been much) and design parameters (cost, wheel travel and installation).

Example - Yes I am interested, I would like to spend 5k for a 10 to 12 inch suspension system using stock mounts, etc.

I might be interested in a bolt on medium travel option in the less than $4k range.

You could get 2" of extra travel by selling the 100, adding ten grand, and buying a 200 series...

I wish it were that easy, 200 Series around here start around 45k and go up from there, that is also with about 60k plus on miles. I don't think I could stomach wheeling a rig that expensive.
 
Total Chaos looked into doing a 100 series LT kit and decided it wasn't worth it with the amount of time and effort it would take to convert everything over. Big one dealing with the reinforced torsion bar mount on the frame and coming up with a coilover bucket on the frame.

Quitters.
