First post, after a lot of searching...

Planning on picking up a RCSB Silverado, 2016, Z71.

Need to tow up to about 6klbs. Not opposed to helper air bags, but want truck dead level unloaded, with enough drop to be recognized, but still enough room for 22x10, -24ish offset, preferably a 12.50 mud terrain. Doesn’t have to be 12.50, but I want wide without stretch.. and with a strong shoulder of a mud terrain.

I think it’s on the outskirts of possible, with a little trimming, and think a 2/4 or 2/5 would be best option.

Problem is that I see some kits at 2/4 level, and some kits with 5” rear drop still with a ton of rake. I know there are tolerances and all, but on average-what rear drop gives dead level rear on a 2” front drop?

Or do you think this is unreasonable, and I should just drop the rear level and run 33x12.50s on 22x10 with stock front end?

This was my 2015 on a 2/4 drop with 22x10 wheels. I think the tires were 305/45/22 which is pretty close to 33x12.0 and I was already rubbing the fender liner.

With an even wider mud tire youd definitely have rubbing issues. I would do a simple reverse level, and call it good. 7b72bbddb68c25be5c0f20b88461ed5d.jpg

2" drop shackle and pull the leaf block and leave the front, it'll be dead level unloaded. I would be willing to bet that 22x10 with that offset and an aggressive tire will be close to rubbing stock so I can't imagine it'll work with a 2" drop up front.

2” shackles with block removed. And a set of homemade custom bracket for airlift bags. It’ll sit level with out without load!

Yea when you order from atomic he asks you to measure the distance between the center of your rim to the bottom of your fender and he determines what parts he’ll send. That’s why I went with him instead of twisted. 

Well, after much deliberation and mathematical equations using the formulas at the Viking website and Ridetech's coilover formulas I found out that our truck geometry calls for a 12" spring with 800 lbs/in for a 1" drop by spring... so, no wonder I am still bottoming out even running the coilovers at 17/15... I ordered some AFCO springs at 850 lb/in, and if the Vikings can't handle them I will buy Ridetech's coilovers and use the Vikings on the rear once I do the 4 link suspension. 

 

As a side note, I did ran the 10" math, and they suggest a 1000 lb/in, but this is with the OEM LCA. I had no idea the LCA had so much influence on the spring rate of a car.

Damn man you went all in on that research and calculation stuff lol. Awesome. Tbh I’m not all that knowledgeable on all that. I just trusted them at atomic and hoped for the best and it turned out great. You sound like you’re on the right track for a smooth ride though! Are ridetechs better? I never read any posts with them in it.

To have the truck level, you need a 3" difference between front and rear. Almost every 2/4, 3/5, 4/6 drop that I have seen will result in a little rake. Here is a pic on my truck, it's a Crew Cab, and I have a 3/5. That's with a full tank of gas and some tools on the bed. Bed empty and it is more noticeable.

They are certainly better as far as that they actually asked you for measurements. I think Ridetech uses Fox's coilovers, as their main thing is Air Suspension. Their HQ's are around $250 each, no spring, but are single adjustable. Their 3 way run at $850 I think each. I have a very nice ride now, better than most cars on the road for sure. But after all the investment in suspension that I have done, plus the 4 link in the rear, that will not cut it. The fact that I am traveling down almost 3-4" hitting on the top of the inner fender metal on a coilover that is supposed to have 5.25" of full travel is not good. I bet once the 850lb/in go in I will see the 2-3" on compression I am suppose to have. That will stop me from bottoming out, at least on the highway. 

 

Ridetechs are very popular on the muscle car scene, mini trucks from the 80's-2000, and HotRods. They have a few systems for fullsize trucks, but nothing for ours at this time. But since I already have the mounts for the Vikings, I can use those to mount their universal fit shocks, or I can reverse engineer them if I need to make them a little wider.

Yup I agree with the 3" difference front to rear in order to achieve a more level look. I am currently sitting at 2/4 with my truck and will be adjusting to 2/5 this spring for a more level look.

Truck looks great !! Getting my 2/4 drop installed tomorrow on my 16' reg cab wt. Might have to change my wheel/tire setup. currently running 20x10 -24, 295/45/20. so my wheels stick outside of fenders about 1"

Looking for some info on drop and tire sizes. I’m thinking 24” reps and maybe a 305/35 or so tire, not sure how much I want to go down and look good but not be too low. My truck is currently lifted and just looking to change it up some anyone have pics of a 3/5 and 24’s with a 305/35 tire or something close?  Pic of my truck as it sits now

      Can anyone explain why the oil pressure runs higher after the DFM is shut off?  just installed the Pulsar Lt.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
