I just installed a set of Rancho Loaded quicklift struts on my '13 screw 4x4 157" WB and I'm experiencing a fairly harsh rebound when I go over a speed bump at a speed any faster then a crawl. It feels like the front suspension is fully extending before any weight is back on it. I've tried adjusting the setting but that only seems to change the shock's compression firmness. I've tried the fronts at settings 2, 4, and 6 and they all have the same harsh rebounding effect. I'm otherwise really impressed with the ride quality when driving in normal conditions and even over bumpy roads. Has anyone else experienced this? I only have about 30 miles on the new struts so I'm wondering if this problem will go away after they settle in. Thanks for the help.

I know i had some wierd behaviors and noises when i did my 5100s after around 500-750 the noises and wierd behaviors started to seem to correct it self so id say let the suspension break for a while then move from there

I have the same set up on my 2011 fx4. And I have had other leveling kits before do the same type of thing. It's because the suspension is almost at max drop already. The harsh rebound you feel is the upper Control arm and ballpoint maxing out. Unfortunately the only way to solve this I belive is to get new upper arms. I haven't done that due to the cost. But maybe someone else can comment on it.

There is a thread in the 04-08 section about a cheaper uniball control arm solution

The quicklift is brutal. Had it on my truck for a very short time. The rebound got so annoying over speed bumps I had to remove it.

And what leveling kit did you replace it with that didn't do the same thing?

Thanks for sharing. That makes sense.

Thanks for the reference. I just read all 22 pages of that thread and learned a lot about UCAs (ball-joint vs uniball). Based on the reviews of those ones on e-bay, I think I'm going to just endure the harsher rebounding until I can afford a name brand one.

The kit combined with bigger tires does make for an overall stiffer ride and harsher rebounds indeed. I've just learned to take it easier on larger bumps or poor roads. :-\

I had the same thing happening when i first installed mine. Stiffened up the ride a bit from 4 to 7 i believe and it no longer happens.

Kinda bs as unless you want to live with the brutal rebound over speed bumps and such, you cant have a soft ride with quicklift.
