Bilstein 5100's with stock UCA? (1 Viewer)

Anyone running the 5100's with stock Upper Control Arms? Have you jacked up the front to see how far it droops down?

I'm running them with SPC's, and my droop is limited by the ball joint hitting the coil. I would think stock UCA's are being tortured with the 5100's if they are drooping that far.

I have them with Stock UCA. They don't hit the coil.

Are you sure the ball joint is not binding up, and acting as the stop? Do you know which Bilstein part number you have?

It would be tough to figure out if the Ball Joint is binding with out removing the upper arm from it's inside mount. I am jacking it up today. I will see if I see a way to figure this out while the wheels are off the ground.

The OME is 570mm long
5100 is 573mm long

Standard Prado is 540mm. Thats the Prado not the GX. I would assume the Prado uses the same UCA. So the 5100 is about 1.5 inches longer then the stock. OME says THEIR stuff works fine with Stock Suspension parts. Seeing how the OME and the 5100 are the same basic length you would hope they both work with the stock UCA.

I wonder if the Droop is the same with only one wheel of the ground as two. I will experiment with that as well. I have had two opposite wheels off the ground exactly 1 time in my life on a 4wd road. NEVER had both the fronts off the ground at the same time. If you do that often you probably need some limit straps of some sort.

1.2x" longer is fairly significant, when you multiply that by the actual travel ratio. Figure an inch of shock travel is almost 2" of suspension travel. It's basically the same, or more than an extended travel icon or radflo, which require aftermarket UCA's.

My math could be a little off - but when I have one wheel jacked off the ground, it's definitely hitting the coil. I get almost 4" of down travel before it hits - and this is with a little more than 3" of lift height (which should take away from down travel). My old Tacoma would lift the wheel off the ground after a bit less than 2" with the extended travel Radflo's, at 3" lift.

I remember when I was putting the whole thing together. The upper control arm was hitting the spring. But now that it's all together and I've driven it when I lifted off the ground the upper control arm is not close to the spring. I think my swaybar is eliminating the problem.

That's sort of where I was going with this whole thing. The KDSS sway bar just disconnects itself and doesn't limit the droop at all.

I didn't have a way to get the one side Up with the other side all the way down in the time I had on hand.
