Replacement UCA's vs Stamped Steel

reardiff, I have personally seen two leveled trucks with stamped steel control arms where the ball joints failed.  If you look closely at them, the angle is terrible, combined with a really weak seat for the joint.  Both had oversized tires and some mileage on them.  But if you're worried about it...yes it CAN happen.  Get the arms, they are much beefier and angles are way better.  Rough Country makes a set for $250 also.

I had rough country 1/2" spacers on the front and the factory tires rubbed very lightly, I only notice when I pulled the tires to install eibach in the front, I got a 16.  I bought the truck used with them in already.  I have stock AT wheels and recently installed 275 60 20 Wildpeaks and they definitely rub more at full lock.  Looking to do control arms in the future to mitigate, gonna monitor the ball joints on the uppers to see if they get sloppy.

This is actually what I was planning, 1.5 level and  a set of 275/60/20 KO2's and calling it a day. Nothing to extensive.  I certainly don't want to cheap out and do something half a$$ed but also don't really want to shell out extra money if there's really no need.

 

Appreciate the comments, so it sounds like unless you go with a larger level (over 2 inches) and/or a larger/wider tire the stock UCA's should work.  

 

 

not sure if you already pulled the trigger, but my recommendation would be jumping up to the 34" 275/65R20 KO2's - with these BFG's (and most 33"+ tires) you are going to an 8 to 12 ply LT tire D or E load rated that will be MUCH heavier than stock, so w/ the added unsprung weight (and increased height/angles) you get greater wear/tear on the suspension bits/ball joints/bearings/bushings + you will notice a drop in acceleration, MPG, & braking performance. ON the other hand you gain a better/cushier ride, more ground clearance, better grip on/off road - SO all that being said, since you're already going to be compromising on that front, may as well get the 1"+ (for some reason KO2's are a "short" 275/60R20 tire measuring only 32.9" BUT the 275/65 version of that tire is a true 34" height), the better look, AND they are within 2.5 lbs of each other in terms of weight so you don't really get any additional penalty in the MPG/acceleration/braking depts.

 

Stock 275/55R20's 39-41lbs

BFG KO2's in 275/60R20 = 54.5lbs

BFG KO2 in 275/65R20 = 57.3lbs + extra 1.2" diameter over the 275/60

 

You're welcome ;-)

I have a Rough Country 2" with stamped UCA's. Never rubbed with stock tires and doesn't rub with 275 60 20 KO2's. On stock 20" wheels. 

Interesting. I keep reading that many people rub with that size tire on stock 20’s when they level it at all with the stamped arms. I’m going with this tire size this week on my ‘18 with no level (yet).  Still no rubbing? I’d love to go bilsteins at 1-1.8 inches but I’m afraid of rubbing the UCA’s. I’m hoping they’re gonna clear ok with no level but of course I’d love to raise it up some as well after

I’m now running Bilstein 5100’s on the top notch. Still no rubbing.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.
