Level Spacer vs. Coil Over for mostly Highway Driving

Hello,

New Colorado owner here. I already purchased the 1.25" Zone spacers but haven't installed them yet. I put spacers on my Silverado, and the ride was "alright". I do a lot of Highway driving, and my truck will see occasional off road & Trail riding. I'm looking for about 1-2" of lift that will give me the best ride. Between the Spacer, the Eibach and the Bilstein shocks, what would give me the best ride?

I've read on a few threads about using the the Eibach shocks with the stock springs. Is there different ones for with and without the Eibach Springs?

Also, I can't find the Bilstein 5100 shocks for the front. All I find are the ones for the rear.

Thanks in advance for the help, I just only want to do this once.

the spacer will give the better ride, as it does not compress the springs like the other 2


for the front Bilstein shocks, well, there is a thread on this, and they are not to be found on the internet but seveal have bought them thru their local off-road/truck dealer, but the last comment on that thread was over a year ago
also in that thread someone mentioned theat Eiback made them for Bilstein but was never confirmed

In my opinion replacing the struts with any of the RHA options will perform better than stock struts with spacers, BUT I do agree that over-pre-loading the struts to gain lift reduces performance of that strut. That's why I went with the Eibach kit with their springs. The springs add 2" and the shock can be left unloaded or only slightly preloaded (.7"). This greatly improved my ride over stock and got me the lift I wanted.

Just my 0.02.

Donít the Eibach spring have a higher spring rate? Should that give me a harsher ride on the highway? Could I run the Eibach with stock spring? I thought I read that would give a better HW ride, but not as good off-road.

I wouldn't characterize the Eibach ride as harsher. But I think it's true that you "feel more things happening". Most people describe the suspension change from stock as more controlled, confident. I feel more "events" from the suspension, but all events feel better and more controlled. Body roll is greatly improved, which is nice for on-road driving (and off). With the stock suspension, I felt just plain unstable over basic things like bridge transitions or significant concrete expansion seams on highways. Certainly washboards of any kind or railroad tracks were a mess. The Eibachs make all these *significantly* better (and safer!).

I imagine the ride is similar with or without their springs. I don't know the spring rate difference, but I imagine they are slightly heavier, yes. The primary spring difference is it's just taller (providing that 2" lift over the stock spring). You can run the Eibachs with stock springs. You'd probably get a *slightly* softer version of the Eibach ride described above.

That said, you're not going to get the lift from the system at that point, so you'd be back to the spacer solution. While you could crank up the height setting by preloading the shock (each notch adds about 0.7" lift up to ~2"), you're reducing the useful compression and ride quality of the shock as you do that. Plenty of people do it and are fine with the ride, but you're particularly interested in ride quality, so it seems counter to your goals.

I agree with @asesino .

I think for the best highway ride while still lifting the truck the Eibach Pro Truck Kit with the shocks at 0" (bottom ring setting) will result in the best possible ride and handling charcteristics. Yes the Eibach springs are a higher spring rate than stock but only marginally (25lbs or so IIRC) They are still pretty soft, especially once broken in. As stated above, you will feel more of the road but it's not harsh and the difference in control and reduced body roll is night and day. Alternatively you can order up a set of Fox or King 2.5 coilovers and have the springs and valving set up custom for your exact needs but it'll cost you well over $1800 and is overkill for most people. But if money is no object then buy once cry once as the saying goes.

The ride on my truck improved greatly when i removed the spacer and went with the bilstien 5100ís at 2Ē setting. The physics with the bilstiens are better than with the spacer.

Hey! Now I'm curious.. Did you just remove the OEM absorber and install this in it's place to get the 2" rise?
A little more info on this is greatly appreciated!

I initially had a 1.25Ē lift/level kit spacer installed to level the front. I changed to the bilstiens later, those have their own settings in place of the spacer, you dont use both together. The lift/level kit spacer is a fashion item, the bilstiens accomplish the leveling while retaining better function/physics and getting you better dampers.

If youre noobin on suspension, go to f8lís thread on how to lift your colorado. Itll answer 80%of your questions and prob bring up a couple. Its in this subforum.

Alright, you guys talked me out of the spacers, going the Eibach route. Going with just the shocks at 1.4", and will add springs later if I want to go a little taller. Thanks for everyone's input!

Either shock will be better than a lift/level spacer, eibach or bilstien

Bilsteins on the top notch ride great on the highway. I just did 10 hours in one day and was comfortable the whole time.
