Parabolic Springs

Here are a few shots to calm the mob!

We are still testing the springs, trying different leaf and shock combinations, spacers, shackles, etc. I know it is taking a long time but we want to make sure everything works, fits, and rides great before we start produceing kits for sale.

Thanks,
Steve

Are those extended shackles?

Just trying to gauge overall lift with the pictures you posted.

And this doesn't appear like some crazy hi-tech technology. What would deter a stateside spring maker to start to make these upon seeing loss of sales from traditional leaf springs to parabolics?

The shackles are extended, as I mentioned, we were trying different spring combinations. The pictures show a few different lifts actually. We got as much as 6 inches of lift and as low as 2.5 to 3 inches of lift by removing leaves and changing shackles.

I believe the main difficulty in developing these springs is the tapering of the leaves. You can notice that the center of the springs are thicker than the ends of the springs. Parabolics are nothing new to the U.S. market, just new to the Toyota market. A lot of larger commercial trucks are using parabolic springs from what I hear.

The shackles are extended yes, because of the arc of the springs, stock length shackles ending being too short for installation. The pictures show a few different lifts actually. We got as much as 6 inches of lift and as low as 2.5 to 3 inches of lift by removing/adding leaves and changing shackles. We also loaded up the vehicle with different items and people to see what it would sit and ride like.

6 inches:eek: :eek: :eek: !!! Wow sounds interesting but how many inches did you get in the las pics?

I'll like to have a 5 inches setup, let us know every detail of the lifts and when are you going to start selling it.
 
Thanks really thanks for share those pics .. looks awesome.

Comments about the ride .. softness and flex . ? did you have some pics with parabolic setup in articulation ..
 
There is a company in Australia called Westalia Parabolics also from what I am told. I put an anouncement for a spring set up in the wanted add about 6 months ago and a guy on there was selling some from Westalia. I was very reluctant to buy them because I didn't know of their quality. Damn I wish I had taken up that offer to buy them now.
 
Steve-

I assume the price listed is per leaf pack, not per set? The site says "leafs"

Do these leafs use stock sized bushings or are they special?

The description says "must use anti inversion shackles," so this means that my heavy duty extended shackles won't work?

What are the TNT springs made of, and how do they compare the the TIC springs as far as ride and load carrying cupacity?

Thanks
Jonathan

Steve-O, what can you tell us about the options for an FJ62? I'm looking to replace mu suspension soon and it's nice to know there may be another option. I, for one would like to have an option to go a couple inches over stock. Anything decided for the 60 series trials?

Edit:

Oops, just looked at your link, didn't realize you were taking orders. So what is a "total package" that's recomended and what shocks and shackles are there to consider? There seem to be variables that aren't mentioned to determine the resulting lift...

They are priced individually yes. We should have complete kits out very soon, I just wanted to get the individual springs up for people to see and learn about.

They will use stock or OME bushings. Our part number is 2187. OME part number SB1.

Extended standard shckles should be fine, we still reccomend anti-inversion shackles for all lifted springs though. You can get an anti-inversion kit from us or OME for pretty cheap.

I dont know they exact material difference between the two springs. We order both from the same vendor, but they are made in different manufacturing plants in entirely different countries in Europe. The TIC springs seem to be stronger so far. I like the ride of the TNT personally, they are softer. Over the next year we will be trying to combine both brands so there will be no more confusion on this.

Thanks,
Steve

Like most of our kits, we will have a few different height and ride options. Other than the fact that they look and ride different, almost all of the other components will be the same as most suspension kits on the market. I will almost always recommend OME shocks and 4+ hardware. :D

Do you have any pics of testing the flex on these springs?
