I just purchased a 2019 RST that came with a 4" readylift,  1/4" spacers, 295/65/r20 toyos on the stock rims already installed.  I noticed recently that it looks like my upper control arms are being rubbed by the tires either when i go full lock or maybe when I hit bumps.  I was wondering if anyone has installed the 1/2" spacer on this type of setup and had any troubles.

Reading about the SST lift from Ready Lift (I'm actually going to go with the SST lift for the Trail Boss), they require a 20" wheel with a +0 offset.  The 18" factory wheel hasn't been tested by Ready Lift, but I think it does sit too close to the larger upper control arm.  1/2" spacers should do the trick, but I'd be more concerned about not having enough thread on the lug nuts.

I know when you start getting into lifting trucks some sacrifices have to made but I really like the stock wheels and the tires size that is on them.  A friend of mine with the same lift just got 1/2" spacers and they seem to be working.  Installer said he had just enough thread for them to feel comfortable about putting them on.  I worry though.  Last think i want is wheel to come flying off.  haha. 

 

Other than the occasional rubbing on the tire is there any real harm being done to the truck by letting it rub?  I am damned if i do or damned if don't in this situation?

Sorry to hi-jack the tread but always curious about the 4" SST by ReadLift.  Their product page says they don't recommend you use Auto 4 HI.  Have you had any experience on what happens if you do?

I went with 5/16 spacers on my truck, and that is as thick as I would comfortably mess with.  I would order some 1" Bora hubcentric bolt on spacers, and cut the nub off of your wheel studs.

That tire is too wide for the stock wheels and the UCA's in the sst kit. You have to stay below a 11.5 in order to not rub.

 

A lot of people with the 18's are going 285/75/18 for a true 35 that is only like 11.3 wide in order to not rub. Id assume that the factory 20's with the same offset would still need to be under that 11.5


As for readylift saying to not use 4auto its because of how the system engages when in that mode that can put extra stress on the front diff in sort of a jolting fashion. This is made worse with the lift when you don't drop the pumpkin like the larger kits will almost all do. They aren't saying you cant use it they are saying it increases the risk of damage due to how it operates

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.
