Funny, i looked for the same thing back in November of 2015. I feel the front is just not level or as level as it should be and I have my icons cranked down.

I remember I found some articles on the 120 forum and the FJ forum about guys running thin spacers to level out the driver side lean or trying to get that extra bit of lift to level out on Tacomas or FJs. I believe the posts were from 2012. Many of the responses from other users were warnings of bottoming out the shocks.

On my rear 3" springs i left my cornfed 1" spacer on to correct the drivers side lean which did work, but on the front coil over.... no idea.

I personally have never seen it on the internet or up close in person.

Let us know if you find anything.

What is the spring rate of your coils? Aftermarket bumper/winch? I believe most out of the box Icons come with 650# coils but I have seen a few with 600# coils as well. I have Icons on my 5th gen (650# coils) and it easily lifted it 3", you may need heavier coils. I think you can crank them past 1.5" of thread showing and be ok though.

you could slip a spacer in there to get a little bump, if you could find a spacer to fit the tophat. Its not the same shape as the top of OEM strut.
You also can crank the coil down a little bit beyond 1.5", issues arise when you've cranked it to less than the compressed length of the coil, then when it bottoms, the spring compresses on itself and crushes itself.

But, the correct way to achieve proper ride height is to suspend the vehicle with the proper spring. You need to up up your rate to a 650 or 700# spring. Easy to do, and then you did it right. It'll ride much better than a cranked down over compressed lightweight spring

Yeah, I have no complaints with my 700# coils + V8 and stock front bumper even. Need to measure how much of threads are exposed but I have a full 3" in the front.

Someone smart probably replaced those with taller coils haha.

You should buy icon or king coils in a longer length, like 14". This allows a taller lift with less preload on the spring. Just a thought.

I though about the same thing. To put spacer. The way it came from icon i like the way it rides. Am afriad if i crank it up a bit itll change the way it rides.

It will change the way it rides.

Another thing to consider. The coilover assemblies designed for our trucks have a specific length when fully extended. That length is determined by the optimum travel range of both the suspension linkage, and the operation range of the CV joint. Adding a spacer on TOP of the coilver may likely forces the knuckle droop to be further than what the CV can accommodate. I.e. extreme CV angle when either of the front wheels is nearly unloaded.

Consider the scenario in which you're climbing up uneven terrain. One of your front wheels completely unloads and that CV angle is now way past the normal operating range because of the top spacer you added. ATRAC kicks in, and locks the brake at that same corner, and now your drivetrain is transmitting intermittent torque through a CV who's angle is very close to, or maxed out. Bye bye CV joint.
