So I have that “ranger lean” real bad with my truck, a smidge over 3/4 of an inch low on the driver side rear. Had the same problem with my colorado, drove me insane, a fixation I could not and still cannot get over lol

so, I’ve ordered these leafs and am planning to install them here soon. My plan is, to attempt a lean fix, is to install the passenger side without the add a leaf in, for an increase of .375”, and then install the add a leaf section on driver side for an increase in ride height of 1.125, making up the 3/4 inch difference side to side.

thoughts?
By no means an suspension expert, but I would expect having what is essential two different spring rates on the same axle could make for some wonky handling characteristics.

Yeah, I imagine it would, but I think at this point I’m willing to endure whacky ride/stiff ride on one side to fix my madness lol short of this causing some sort of serious detrimental side effect to the truck

I'd install the icons and see if you are still 3/4" low. It could be your factory leafs out of spec. If you are still too low look into lift blocks that bolt into the leaf pack via the center pin. 1/2" blocks are common on Toyotas. You could make one out of 3/4" bar stock and buy a new longer center pin.

Thinking I will do this. I’ll put them in with no leaf and see what that gets me. Thanks!

So I got these on with option 2 installed on the driver side and option one installed on the passenger side, with the factory shim on the driver side. They’ve been on since last Friday, did a road trip and they have about 800 miles on them.

Right now they’ve lifted the rear end way more than advertised, hoping for some serious settling. My before measurement from ground to the center of wheel well was 38.25 on P/S rear, and 37.5 on D/S rear. After install on my last measurement (it varies every time I move it, but still always measuring from same spot in my level garage) was 40 5/8 on both sides.

truck is still visibly crooked though, and that’s because the D/S front is 1/2 inch lower than the passenger side. Sweet!

I have not noticed any adverse ride effects from having a stiffer spring on the D\S so far, but I’ve only done on road driving so far.

I installed these and have been driving with them for 2 weeks now. I bought these for a number of reasons and am super pleased with the results. I wanted to address two issues. 1) The front-to-back rocking or boat feeling with the OE spring. 2) Rear end squat when loaded.

I have a decked drawer system fully loaded with tools and a bed rack that carries a case of recovery gear - All of which I drive around with daily. The Decked system is 205 lbs and I estimate I carry about another 150 lbs +- 10lbs. Per Icon's recommendations, I installed them in the number 2 configuration.

Pros: Lifted the back end up. Super smooth ride. The rocking was drastically reduced And now I can carry even more weight before leveling out.

Cons. Even at the recommended constant load for configuration 2, there is a noticeable lift above stock on the rear. Two inches at first now about 1 inch. which created an even more exaggerated rake than stock and dropped the front number about an inch closer to the ground.

I can't comment on shudder since mine has never been significant on my truck. Other than the leaf pack, my suspension has been stock. I installed the Zone 2" leveling kit yesterday and now love the look (slight rake) but can't comment on the ride quality until I get an alignment tomorrow.

For someone looking to improve the ride quality and isn't carrying a whole lot in the back daily, I'd seriously recommend this with the option one setup. So smooth even with stock FX-4 shocks. I'll check back in after the alignment

That seems like a really bad idea.

Shims or a block would be a much safer, and cheaper option.

On its face it always sounds like a bad idea, but then I think, it’s just a stiffer spring rate on the side of the vehicle that carries more weight, which is how certain other vehicles come from the factory.

Ive heard on this forum that blocks are terrible for springs, and also that there’s nothing wrong with blocks lol who knows. But she’s sitting level in the back right now, so we’ll see how it turns out in long run

I don't know about that. I've done suspension work on dozens of vehicles. I've never once seen differing rates used left to right.

Blocks bigger than an inch or on front leafs are a no-no in my eyes, but I wouldn't worry about a tiny one in the rear.

Did you give Ford a chance to sort this out first?

Good news is your fix got you a nice set of springs as a bonus.

Are your measurements in the rear the same on both sides?
Pretty damn even. a little lower on the passenger side right now because I'm parked on the street. Image 1: Passenger Side. Image 2: Driver Side. Don't judge me for wanting to get every penny out of these stock tires before I move up :p

I skipped Ford on the fix, read through the thread on the lean and saw that pretty much no one got it fixed through them always citing the lean is “within spec” after Ford having the truck for days. I also fought this same fight with Chevy on my colorado for a while, with Chevy always giving me the same response. I solved that one on my own by installing a ZR2 leaf on my Z71 driver side (ZR2 springs gave a 1 inch increase on ride height over non ZR2’s), which leveled it out. Ran it like that for just under 3 years with no known issues. Those springs had different part numbers for left and right with no identifiable difference between them, so I didn’t know if they were different spring rates, no one at chevy ever knew either lol

The bonus of fancy new springs was definitely how I looked at it too! Lol softer spring rate and all, ride does feel better
