That's good to know that turning them up helps with the rebound.

I agree. The main reason I bought these was to soften up the ride a bit; the 2" lift was nice but now I'm debating either removing the quicklifts and replacing it with the stock height Rancho 9000s (rs999804) that use the OEM springs or enduring the harsh ride until I can afford to put on some uniball UCAs.

Does anyone have experience with uniball UCAs eliminating the harsh rebound from Rancho or bilstein coilovers?

That is not their purpose.

This or the 5100s are th opposite of a softer ride!

To achieve lift they preload the springs which adds tension. This is why going over speed bumps they top out, you may not even have the arms contacting anything but just topping out.

If you want softer ride then go with a puck level with stock springs.

I have to disagree with you there. The Rancho quicklifts with the 9000 series shocks set at 2, 3, or 4 provide a noticeably softer ride over stock even with the preloaded springs. The exception is feeling the suspension fully extending after speed-bumps. Since a puck level also pushes the suspension down without adding travel, I can't imagine they would provide a softer ride then coilovers.

Interesting as all the settings do is control damping of shock and has nothing to do with spring. Maybe they run a softer spring rate vs stock?

So all of my research is showing that all leveling kits (coil overs or spacers) installed w/out uniball UCAs create the same situation xtream described earlier in this thread and reduces downward travel by the exact amount of the lift provided. This in turn creates that harsh rebounding effect when the wheel goes in a pot hole or after a speed bump.

After reading Buellracer's thread below on Fox 2.0 coil overs and shocks, I'm convinced those will best meet my need. Their coil overs come from the factory set to provide a 2" lift but you can turn them down to adjust the lift from 2" down to 0" to get back the amount of downward travel I want. Now I just need to save up the $1k for them. I do think I'll try the rears first which are only $120 a piece. Thanks again for all the help.

For me personally, at $1k I would entertain a lift.

I just put on Quicklifts a few weeks ago and instantly noticed the lack of droop. I measured the lift and it's just under 2" leaving me with only 1.5" of droop before i have a free spinning wheel in the air. I had never read this complaint before but I haven't read that Fox thread linked above yet.

The marketing I see from Bilstein and Rancho point out that these lift struts prevent over travel but they confuse that by saying they offer more overall travel. I feel like a normal spacer offers a better balance but have no first hand experience with one. It's my understanding that spacers allow the suspension to over travel down but on the flip-side reduce up travel in an equally bad way.

Am I wrong? I bolded your quote where you say the spacers cause the same lack of droop...are you sure or do they just cause excess wear from too much droop?

Would love someone with a 2" level spacer to check and let us know.

I have the daystar comfort ride 2inch and if anything I thought the truck rides better. I almost got the quick lifts. After reading this I am thinking I made the correct choice. I have always had good luck with day star products so that's why I choose them.

That's interesting; I hadn't seen the "prevents over travel" claim. To answer your question, l'm not sure that spacers cause the same lack of droop. My tying the two leveling methods together, with respect to this issue, was based on reading multiple sources about the need for a longer traveling UCA to gain back downward travel.

When installing my quicklifts, I noticed that once the UCA was detached, the suspension dropped roughly 2 inches so that further supported the idea that my UCAs were the primary limiting factor for downward travel. While typing this response, I'm remembering however, that before detaching the UCA, I first loosened the 3 nuts on top of the strut and unthreaded them up about an inch. So if they were preventing downward or "over travel" I wouldn't have known. So you may have a point, if leveling struts do prevent over travel, then spacers may actually provide more downward travel assuming of course that the OEM struts don't also prevent over travel.
