Definitely. I'm thinking 0.5-1.25" top hat with the 5100s. I have the shocks ordered. It's just a matter of adjustment w/ installation now.

 

I have to get a front and rear spacer as well, considering the rough country kit and selling the 2" lower spacer.

Exactly the kit I used and sold lower spacer. Good luck! Well worth it.

Just contacted Rough Country and they sell these parts individually but you have to call. Therefore there is no need to ditch the 2" spacer. Just an FYI for everyone.

 

Part # 1306 is the top hat (0.5" spacer) only. $29.99USD

Part # 6532 is the 2.25" rear block and u-bolts. $59.99USD

I was planning on running bilsteins with lower spacer. Was looking for 2.25 inches or so. Not 2.5. Plus cognito uppers. Why do you suggest top spacer instead of bottom? Still getting schooled on IFS front suspension. All other trucks I had were solid front axels

Thanks in advance

I'm running similar setup on my '14 HC. Except my 5100s are set to highest setting (1.8") with a .5 in spacer on top in front. And swapped out stock block (1.25") for 2.25" block in rear also with 5100s. Running 295/60/20 on stock high country rims. Barely rubs, and I mean barely, inner liner at full lock. Sits about 1/4"-3/8" higher in rear. As Big Whiskey stated, you can run bigger Timbrens or Firestone Airbags in rear to help with squat while towing. 02f7e2da525089a64b292072e95730c9.jpg

Your truck sits exactly how I want mine. Nice ride. Those tires measure out at around 34" tall correct? I would do the same height but on 18" rims

I did try the 2nd setting before the top. A little stiffer ride on top setting that I noticed but that's expected as I added 10ply tires at the same time. My opinion avoid the lower spacer with the 5100s if you can since they are designed for height adjustment. Anything over 2.5" your at higher risk for premature ball joint issues. All depends on how much clearance you want Really.

 

2.5 isn't the magic cutoff where nothing happens, anything over stock adds wear, the higher you go the worse it can become. A 1.5 inch is adding some wear, a 2.0 is worse and so on. Some people never experience anything, others wear out in 40k miles. Depends on what the truck does, many are just street queens and don't have a failure so they say 2.5 is safe but at 2.5 it can cause premature ball joint wear among other things.

2.5 level front 2inch block in the rear. 20x10 -24 on 33s. Only slight rub on full lock reverse.

Great info , I appreciate your help. I am looking for a moderate level/lift utilizing the bilsteins and a small block. I like the look you created, I will do something very similar.

Don't disagree with anything you state here but I didn't say it was a magic cutoff. Simply stating due to angles of ball joints, typically anything over 2.5" level substantially adds greater risk for premature wear due to suspension geometry. Nothing is "safe"

Can you post a pic of it at full crank where it rubs? I want to run a 2.5 rough country on -24 20x10 and 295/55 instead, hoping with being half inch less it will not rub much if at all. Truck looks great

Thanks. Correct, I believe the finished height on the AT2s in that size was like 33.9" on Toyo website. Ive got over 11k miles on them, still look brand new.

Big Whiskey, Thanks for your help, lots of information I just wasn't sure I was reading it correctly. My wheels are stock 18" with p265/65r18 goodyears. thanks again for your help.

No problem. With a level kit and your stock 18" rims, you have a lot of tire options. 275/70/18, 285/65/18, or 305/60/18 will fit easily (and will actually fit on a stock truck). You should also be able to run 285/70/18, 295/65/18, or 305/65/18 without much trouble. And, 295/70/18, 285/75/18, or 33x12.50x18 might clear, but could require some trimming (or might rub the sway bar at full lock).

I have 285/75r18s on my stock wheels. No rub on sway bar or anything. Very minor rub on the carpet (at full lock) at first, but not an issue. Measures out to a 34.8 x 11.50.

That's pretty sweet. Those are big tires! I didn't think that size would rub the sway bar, since they're not much wider than stock...but thought they could rub the fender liner or mud flaps.

They are definitely beefy looking for sure! Lol. I love it though. Looking at it from the side you would think it would rub the flaps or fender liners pretty good but it doesn't.

Yeah, those look gigantic, haha. They look like they'd rub for sure!

    • I have an Autel, works great for what it is. Can't do some specific things because you need say the GM tool, VCDS for Audi/Volkswagon and others of course. But those times are few and far between for me.   The other tool I'd like to try one day is the new Topdon scan tools. Seen several video's on them and many youtube people review them.    I've never subscribed for updates or payed to do that stuff on my Autel, so I'm sure I'm missing out on some of the updates but I'm fine with that for now.
    • I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?
    • There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.
