King Springs turned LX470 into a pogo stick :(

Hi,

I don’t have any added weight. I have a subwoofer and one of the rear seats, occasionally a few a dogs or landscaping equipment. Typically though I’m the only added weight. I also have an AHC sensor lift of no more than an inch. Still plenty of rake.

The drive was unbearable. Was worst when going below 20 miles an hour. When coming to a stop the truck would bounce up and down rapidly. Going over any bump sounded like the truck was bottoming out. There’s always a chance they were installed incorrectly, but I doubt it.
Something about my trucks weight or globes didn’t meld well with the springs. Sometimes I wonder if the pressure readings coming from the Plaeides spheres need to be at a different level than the OEM spheres.

I apologize for the confusion, my post was intended for @Clunky .

FWIW, if your goal is a sensor lift at factory weight I would just add 30mm spacers to the factory AHC springs and crank the torsion bars to add preload. King springs are valuable for added weight, but the spring rate will be all wrong at factory weight. At factory weight, you don't want King Springs, IMO.

CBT accidentally put LC springs in a few years ago. That also resulted in pogo stick ride. This was with OEM spheres (a few years before my Plaeides spheres).

However, if I remember correctly, there are 2 different height options (about 30mm difference) with LC springs and I had the taller ones.

I used the landcruiser ahc springs.... I’m assuming this makes a difference too. I can’t see how that could be much difference than the Lexus. The non ahc LC springs are twice the price and I’m assuming twice as much metal..

Does anyone know the difference between the 2006 land cruiser versus LX AHC springs?

There was some similar discussion the thread linked below, before and after Post #165 at Page 9 -- not sure whether it will help or just add to the confusion:

Coil springs for AHC

It does not add confusion and imo helps so thank you, it was that thread that allowed me to feel comfortable choosing the 06 ahc landcruiser springs for my 06lx. The dampening adjustment goes from very stiff like a roller coaster to very plush. I use setting two or three from the left. All I did was adjust torsion bars to get the pressures within range. I’m sure it can get even better with sensor tuning.
