Front Coilover for the 100

[cruiser99]

I heard this failure rational before (I think it's Toyota's) and I hate to say that it does not make sense to me (did some modeling). I guess it's possible.

Even thought I have not heard of a UZJ failing (which actually contradicts the bump stop impact theory); I still want to do what you guys did. The same pictures were "published" on the COOL list and to my opinion welding is the only way to go.

I agree with you, increasing the travel is a BIG job. However want to make a rock crawler out of a 100 should look elsewhere. IMO

Easy for you to say Doron. You already got a 40! ;p

Julien from All American Imports is on the LCOOL int list.

I have been playing witht he coil over for 100 for some time, and it wont improve travel, as the ball joints are the limiting factor, but they do allow you to toss the torsion bars.

Toss the torsion bar?

Does this mean Marlin Crawler can now fit in 100 series as long it is fitted with front coilover? I recalled Slee said there is no room to put crawler gears due to the torsion mounts?

Cheers,

I don’t think the coil-over in the picture above is large enough to carry all the front suspension loads. I think it’s more for added load carrying capability.

Not sure where this comes from.

Can you 4:1 the 100 Mr. Slee?

I had to doublecheck & triplecheck my dying & aging cells brain once more time, it is something I do recalled form the "expertise" and it turned out to be from this web site, not slee's web site.

Slee, pardon me for confusing you as the source.

See "100 Series" paragraph
"The Crawler transmission will only fit 100 Series live front axle models. The IFS models have a crossmember that supports the rear of the IFS torsion bars, this crossmember is directly behind the transfer case and does not allow enough room to fit the crawler box."

So I thought it would be cool to have thus special feature installed on our 100 series! Yes, I know it will not make up for the IFS drawback but at least it is one step closer......

Yes, I remember reading that. DAMN!!

 

[calamaridog]

Well, I'm already hatching a plan to take the new rig down to Camburg and have them fabricate a sweet coilover set up for my new 100






Then again, reality keeps setting in Maybe after something fails I could justify it...

 

[the shed guy]

We stitch welded it, so if a weld cracks, it wont crack right around the bracket.

Its also, plug welded through the bolt holes, and welded internally on the join of the 2 parts of the A arm.

Need to send someone down there to teach you guys to weld. Maybe to many JB stubbies?

conversation with coilover maker

ran across this webpage and I wanted to inquire about the product on this Toyota Land Cruiser 100 Series. I am in California and I wanted to get a pair of this suspension pieces. If you could please give me any information on this I would really appreciate it! Thanks very much!

Dear Sir,
What type of Landcruiser do you have: is this one with independant front suspension ?
What suspension parts are you interested in: heavy duty torsionbars, coilsprings
Does your car have electronic height control?
The car in the pictures is one from a customer of ours.

Hello Amando,
We will have to check for you regarding these parts: these are custom made, do not come cheap Set is based on the 100 series with the camper unit on the rear: will be a really heavy duty set Kit consists of coil over shocks in the front, rear shocks, heavy duty torsion bars and HD rear coils

As soon as we have an answer I will get back to

I hope it can carry the load because arn't the t-bars are missing in that pic?

[cruiser99]

It looks to me that the picture was taken from the front and the T Bars are obstructed by the rotor.

Amando,

I got in touch with the owners of the 100/camper and they directed me to the manufacturer. Still waiting for response.

Doron.

 

[ShottsUZJ100]

Doron: Being a dingbat on this stuff I want to throw out a question to you..........I know a coilover shock is what would be ideal. Is it posbbile this person used both the TBars and the Coilover simply to add capability? I'd think the 2 spring rates would fight each other. Am I wrong?

 

[SGT0311]

The camper is made by Innovation Campers in Germany, I believe.

John,

The coil-over in the pic at the beginning of the post is an assist system. Like you said, it purpose is the increase the load carrying capacity of the front suspension. It’s not meant to replace the T Bar.

The 2 springs (the T bar and the spring in the coil over) would work together to carry the load and their rates (spring rate) is added algebraically. Vehicle suspension systems are fairly slow systems so instability (springs fighting one another) is not an issue.

As you know what I do with my truck, sometimes transversing difficult terrain at fairly fast past is a problem for me. My truck is under-sprung (even with the, so called, heavy duty T bars) and the coil-over could help the bottoming out. I suspect that if I install it, I would go back to the stock T bars.

Also like I said before, I think it would help the cracking of the lower control issue. If I could get my hand on the HDJ T Bars sizing, I could do the fatigue comparison.

I hope this helps,
Doron.

Fox have an air shock that would also work like a coil over. The upper mount could be custom machined to have stud version. I have not check the dimension if there is any that would fit. anybody could measure their old shock. I need to find the compressed and extended length.

Gotcha Doron. After I wrote that I thought more and re-figured that the shocks may not fight themselves. (A breakthrough for me )

For what you do I can see you want and need two things:
1. More front spring rate
2. New gears (though I share that desire too for crawling )

For what I do, I need one thing:
1. A front lift that allows for stock droop and compression.
I remember my 100 when stock. It flexed dang near like an 80 and was amazing. It rarely lifted a wheel. Heck, it did 562 RTI on a ramp and stock! Now lifted 2.75" front and 3+" rear the front fights compression therefore lifts tires easier. I would KILL, pay BIG money for a front lift that allowed for my current (or a tad higher) spring rate and lift that had equal up and down travel. MY DREAM! Any manufacturers listening?

Until then, we're counting on you for an answer Doron. No pressure though.
HEY: YOU'RE the GUY that designed the diff drop. Bring us the new front end too!?

 

[cruiser99]

Augie,

I am afraid that the air shock would not work (not for me anyway). The air bag in the shock occupies space along the axis of the shock operation (the up and down direction) which means you end up sacrificing travel length and/or damping fluid volume. Both are not what you want. What’s nice about the coil-over design is that it’s occupying the space around the shock.

John,

I know exactly what I want to do with the front end and I think I know how to do it but since I am back into the construction business (house), I don’t have any time for this. Maybe someday.
