Thread: LLAMS Operation

Correct. It's off-road height but the suspension ecu is still in normal mode so rock crawl will auto-select off-road mode (unless a trailer is detected attached) and raise the vehicle about another 40mm.

Haven't tried any lower than that, which I think is the special mode Extra Low.

Scott, I agree it seems stiffer and quite good on twisty roads at -20, but I think it may be more related to lower center of gravity and possibly this may also have some effect on the damper due to angle of force.

The way LR air springs are designed is that the lower the ride height, the softer the spring, and the higher the ride height, the firmer the spring. on a street around the corner from my house, the bitumen has been patched numerous times, so I put my Llams into low and the D4 rides the patched road much better. The road is not so bad that you hit bump stops.
Kimberly Kampers have designed their air springs in the opposite way to LR so that when you lower their vans/trailers the suspension is firmer.

Lowering by 20mm lowers the suspension roll centre which IMO reduces body roll more than the slight reduction in CoG does, but together have quite an impact. It also makes wheel camber slightly more positive/less negative which improves steering response.

My experience is that it feels bouncier at access height. Maybe it is softer ??? I usually raise to off road height to go over speed humps to ease the bump for my wife as she has severe back pain as it seems softer than normal height. I'm confused.

So in the same note, does the load in the car affect the height and or stiffness of the suspension?

I think thats because at that height theres not much movement until the bump stops, so any up movement of the suspension feels quiet harsh - at least thats what it feels like to me.

As the D3/4 is self leveling, so would increase the air in the springs if the weight is increased, you would have to think the suspension would be stiffer.
That said, the extra load on the more aired up springs might make the car feel the same?

BTW, I was under the impression that it was the rear of the car that did all the self leveling, but a few weeks ago I pulled up to take a wiz, left the car running & the front of the car lowered?

Strange machines these D3/4's. Seem to have a mind of their own & it's not always on this planet.
