I just installed the Terrain Tamer parabolic suspension kit. The difference in ride is hard to believe, more than I possibly expected. My wife said, "Wow!" before we had even got out of the neighborhood when I took her for a spin. It sounds like hyperbole but it is literally a different vehicle—along with the four-wheel-disc brake conversion I'd say it's the best single modification I have done in 40 years of ownership.

The kit came with Terrain Tamer's own twin-tube shocks, but recently Koni sent me a set of their Heavy Track adjustable shocks. I think the Koni Heavy Track and Raid are the best expedition shocks on the planet, so I installed them instead, at least for now. Otherwise the kit is complete with anti-inversion shackles and TT's own synthetic elastomer bushings, which the company claims combines the vibration dampening of rubber with the durability of polyurethane. We'll see about durability, but the dampening sure is there. A lot of little buzzes and rattles the vehicle had disappeared.

The kit provides a 50mm lift, identical to the OME kit that was on before. The ground to fender measurement is within a half inch. Oh, and . . . the new springs removed 80 pounds from the Land Cruiser. Look at the difference in front spring weight.

Can you turn the ride of a leaf-spring FJ40 into that of a coil-spring Defender 90? Close, very close.

The only observation I have is with the Koni shock it has to be removed to make adjustments unlike the Rancho RS9000 XL's. I'll be interested to hear how the springs do over time; how much they will settle since only two leaves.

True about Konis, although you only have to remove one end, and once you dial it in it's pretty much set. We've used Koni Raids on heavily overloaded Defender 110s in East Africa, and nothing matches them for being able to soak up mile after mile of Tanzanian B roads. Nothing fancy about them, just massive oil volume and high-quality construction. I'm curious about the longevity of the parabolics as well, but there's actually no reason they won't hold up as well as standard multi-leaf springs. It's tempting to think, "Oh, only two leaves versus eight?" but it's an apples and oranges comparison.

Someone will have to import these springs to the U.S., and support and stock them. For years, we have all heard about the parabolic springs, but they seem elusive to actually put your hands on.
 
It’s always great to hear an “independant report” of somebody being happy with our products!

Thank you for taking the time to post this.

We have plenty of the Terrain Tamer parabolic suspension kits in stock for various Landcruiser models right here in Northern California. Obviously, we can ship nationwide.
Happy to help!

PS: we’re installing a set of these on my sons cruiser project today.

I just thought I'd add I installed Terrain Tamers Parabolic kit on my HJ61 earlier this year.
It's incredible, I'm not exaggerating but it rides better than my 80 series in comfort.

A short wheel base 40 will be different but if it's even half as good as the ones in my 60 it's 100% worth it.

I'll be buying some for my BJ42 when I have some extra money to blow and I get the motivation to do the spinebusting job of replacing my current Old Man Emu's on my shed floor. If I hadn't bought brand new springs 5 years ago I would have already bought the Terrain Tamers by now.
 
Let us know your revew
The project is a long way from completion.

1958 FJ25

It’ll be his first car and DD as well as short and long distance adventure rig.

Tons of work to be done …..
