Hey guys. New to the forum and i have been searching for days about leveling kits and tires threw many different forums.

 

First things first there are a ton of different ideas or ways to go. And everyone has there own opinion. Im just looking for a good direction.

 

I have ordered a new truck and waiting for delivery. I am looking to put on new wheels and tires.

 

The wheels I am currently looking to put on are the XD Rockstars 2 20x9 machined with satin black accents. and i was told i should put BFG A/T KO2 285/65/20. That set up with a 2.5 Pro comp leveling kit.

 

Upon searching i havnt seen anyone with that set up and was trying to see if anyone had somthing close. Im trying to get a set up that doesnt rub or that requires very minimal cutting.

 

also the Rockstar 2 only have a -12 offset or a +18 offset and didnt know which one would be better. I dont know what the stock offset rims are.

 

The last thing besides rubbing im worried about is the UCA gap being too small and ball joint angles and CV angles. I cant seem to find an answer on other topics so im starting a new one.

 

Thanks for all of your help guys i really appreciate it.

In order to go up 2 1/2in. and do it right is going to require double shock spacers, front diff spacers, upper control arms, pitman and idler supports, torsion bar keys, steering stabilizer, etc.

 

You can go cheap and crank the bars all the way up but the shocks will bottom out as will the upper control arms on the frame stops.

 

You can install aftermarket torsion bar keys and shock extenders but again the upper control arms will contact the frame stops.

 

I can keek going but you get the point, no company makes the perfect leveling kit, you must piece everything together to make one solid setup. Even Cognito (the best) is missing front diff spacers, stabilizer bar, and decent ball joints. All can be adder to make a good kit.

Well with the pro comp keys it says 2.5 but u can raise it from stock to 2.5 so u don't have to crank it up to 2.5 just crank it up enough to fit the wheels and tires. So would the 285/65/20 bfg ko2 fit with out maxing out the keys ?

But when the rear is 3in. taller the the front you are going to want to crank it 2 1/2in. to pull the rake out of it.

 

Pro Comp keys offer nothing over any other lift keys, a lift key is a lift key.

 

You are going to be very unhappy after installing keys and shock spacers, been there as have everyone else, you need a Cognito kit plus a few other parts, you only have to do it once, why half ass?

That tire size is 34.5"X11.5" according to BFG site. With that tire size you will need the +18 offset wheel.

 

You can go halfway level with just keys and shock extenders but you will still have a 2" rake. Like stated above you will need a lot more parts for a true level. If you decide on just keys and shock spacers and have someone do it for you they will probably over crank the TB's

I leveled my 2500 with keys and shock extenders.. Was cheap but it really DOsent ride much different... A little stiffer but I'll take over over the 2500 for the cognito.

20x10 BMF's with -19mm offset and 33 inch toyo MT's, I know of quite a few 11'+ 2500's with keys and extenders with well over 100k on original front end parts that's why I'm not worried about just installing keys. That just my opinon though, everyone has their own about it

Are you rubbing? What did u have to do to fit that? ....... and do u think the 20x9 rockstar 2 will fit with the 285/65/20 will fit with minimal fixing ? And would you be able to explain to me the offsets what is the difference between a -19 and a +18 ?

Yes I am rubbing but It is because I have 20x10's, I'm not 100 percent sure but you should not rub with 20x9's especially with 285's as they are a little smaller then actuall 33's... The extra width is what makes it rub, I'm rubbing pretty good on my fender which I will have to trim and the air dam which I already trimmed. Negative offset means the farther it sticks out and positive means the wheel is going to be farther tucked into the truck.

Not sure, I'll have do some searching I was always under the impression that 285's were 32.5.. Anyone else have any knowledge of this?

 

Either way you should be good, again the width is mainly what will cause rubbing from what I've seen

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By Grumpy Bear · Posted

      Love the look. I'm a SCSB lover myself.    Two items. 1.) A spacer changes scrub radius but this also changes when we use wheels of different offsets. A little isn't a big deal. 2.) Steel wheels, alloy wheels all have different thickness. Same effect on the stud and lug nut as a spacer. When hub centric the wheel isn't supported by the stud. It's supported by the hub. The stud just keeps it all together.

      2016 Sierra 5.3L L83 new injectors now runs rich.

      By JAI3 · Posted

      I had a evap sol go bad a couple weeks ago. . I replaced it.  While watching live data at the time I saw I had some cylinder 1 misfires. No MIL but on live data I could see ~50 at startup and about 70 more after an hour a drive all on cyl 1.  I also noticed that the LTFT were -5% to -15% always.  And that bank 2 is always -3% richer than bank 1. Even across all driving modes, city, highway, etc it’s always 3% richer than bank 1. So I start with the misfire. Swapped coil, plug, and plug wires from 1 to 3. No follow. I got an Injector reseal kit, pulled the D/s injector rail, swapped #1 and #3 injectors, resealed them, reinstalled and retested.  The misfire followed to 3. So I ordered and replaced all 8 injectors, spark plugs, and plug wires. Also replaced the 1 time use fuel pipes under the intake manifold.  Injectors that were in the truck since new were  Part # 12668390.  I replaced them with # 12742701 Got from RockAuto. Pretty certain they’re genuine and the correct ones. I called a friend at a parts store who told me “the 12742701 were the correct superseded part # for the originals I was replacing”. So started truck after replacing all that and it’s running -15 - -30 LTFTs. I reset the fuel trims with GDS2 and drove it for a 60 miles trip each way. There have been no changes in the LTFTs.  I checked if the HPFP was leaking into the crankcase. I removed the pvc and watched the trims. No difference.  I checked the alcohol content and it was at 10%  I’m out of ideas here. Truck seems to run great. Just always rich on the fuel trims.  Anyone with any help or ideas would be greatly appreciated.  I ran an injector balance test just for the heck of it and it came back this. I’m confused.  I have gds2 and some other diag tools if anyone knows of anything I should test next.

      Fix one problem and find another.   Truck didn't have a thermostat in it so I flushed out the system today and refilled with 50/50 Dexcool. This truck is so old (LOL) that it has a sticker under the hood alerting people to the fact that it contains such. There is also an orange supplement with the owner's manual alerting the owner that "Your vehicle is one of a number of late production 1995 General Motors vehicles that use a newly developed engine coolant in the cooling system..."   I was still a little flummoxed by what seemed like a rich condition (exhaust smell, and a puff of carbon with a punchy rev). While watching the coolant temperature and testing the thermostat with my scanner, I happened to notice the IAT (incoming air temperature) to the intake was -40F. I know the temp is below average today, but I can still feel my face, and I was wearing shorts.   D'oh!! I realized I had never plugged the IAT back in, and the airbox was out while I was doing coolant. So I paused, reinstalled the airbox and plugged in the IAT, and viola. Things cleared right up, and I watched the coolant temp climb to a reported 198 degrees on the scanner (195 thermostat) and then it dropped to 194 (open) and then back up to 198 and held. Let it cool, came back, checked the coolant level and was satisifed.   Victory lap?   It needed more than the couple of gallons of gas I put in it from almost bone dry, so I ran it up to the gas station. It had earned it, or, at least I was pretty certain I wouldn't be draining or removing the tank anytime soon.   CEL popped on just as I was cruising a nice steady 40mph, just after coasting down a slight downhill curve.. Of course, it did, because, why let me enjoy not having dash emojis for a little while.   I just happened to have the scanner plugged in. I don't text and drive but I might scan and drive. Don't tell the police.   P0401, EGR flow insufficient.    Well, hello, EGR... ...my old friend! Welcome to the party, now that the engine reaches the factory-programmed operating temperature. I'm sure it was gagging on hostile, rich exhaust and carbon this whole time so I'll take it off and look again.   At least it's easily accessible, and worst case, about $65 to replace.   To keep, or to sell... Hmm. I want it running correctly either way. It's easier to sell when there are no fault codes.   It needs tires (they're aged out and cracking)   It could probably use an oil pan seal, or maybe the timing cover gasket/ junction with the pan needs redone because I've got an issue there that leaves a drop of oil on the floor.   If I do tires I'm sure they'll say the ball joints could use freshening, and, and, and, and.... At some point I'll have to stop. I can't (shouldn't) make it perfect, that's not what this rig is.
