Hey guys, new to the forum, but owned several gm trucks, boosted s10s to mild full size trucks, since early 2000s. I'm to the point where traction is scarce. The truck is a 14 Silverado 5.3 2wd. Owned since new.

Mods so far:

22x9 GM Snowflakes with 305/40/22 tires. Came with factory 20s.

4/7 drop

Hellwig rear sway bar

S&B Intake

MBRP Exhaust (still have cats)

Mild tune via local tuner (91+ octane)

Recently went to 4:10s with powertrax locker. 

I'm getting ready to install my 2.9L Whipple (so the tune will be redone by my local guy). So hooking up won't happen on the 22x9's. I already spin well into 2nd gear.   

Knowing I need more sidewall I'm thinking of running a 20x10 or even 18x10 in the rear for certain occasions... 

Other than good sticky tires, is there something else I can do? I'd love to 4 link or tub, but it's not in cards right now. Never ran traction bars so I don't know how well they work. Just looking for ideas or proven and worthwhile options out there.  Thanks for any and all advice.

1. Get some traction bars. VAS or CalTrac. 
2. Nitto NT555R2 305/50/20 is what you’ll want if you wanna stay with 32” tall tires. Anything else will be around 28-29” tall. 
3. 4.10 is gonna be a lot…. Especially with a blower. I’m running 3.42 and with the blower setup making about 600, 1st is ALWASY useless and 2nd was mostly spinning. 
4. Get adjustable shocks. Something like Viking with a relocating brackets. 
 

Goodluck.

Traction bars, check! Thanks! By relocating brackets are you talking about shock extenders? If so I happen to run a set already. I'll definitely look into the shocks you're referring to. Do you that 305 tire on the factory 20x8 wheel? I want to swap back to my 20s in the winter months here in Illinois. They are in great shape. I might even start running them all year for the weight savings. Might even sell the 22s for more go fast parts. 

Have you done any supporting trans mods? I swapped to amsoil and have the trans thermostat mod to go in.   I really appreciate your help. What blower are you using and what size pulley do you run? 

 

Again thanks a lot for your info! Very impressive number you're at.  I hope to be around there as well.

I’m running 20x9.5 cosmis XT006R 20x8 is probably be way too skinny. image.thumb.jpeg.773a15fbf978dcc417ba1bd684618452.jpeg

 

if you’re running 6L80, in factory form with a good tuner can make it hold 7-800hp. Just make sure to keep it cool. I’m still running just the simple ACDelco dex 6… nothing fancy. Just with a Trucool 40k and a pill flip on the thermostat. Never game me problem until I pushed it into the 800 then it started to slip in 4th. Now I’m running a circle D lvl 4 kit. if you still have the stock converter, I suggest you change it. CTSV OEM converter from a 6L90 is a good choice if you wanna stay with low stall. If you’re planning to do cam down the road, I suggest one somewhere in the 2800-3200 stall. You can run stage 2/3 with that kind of stall no problem. 
 

I was running an Edelbrock 2300. Idk what size pulley I had on it. Made about 12.5psi with stock cam and a really good flowing 3.5 exhaust. I’ve now switched to a fully built 5.3 with S476 on 16psi making somewhere in the low 800 on a good day. 
 

 

This is when I was running a blower setup:

Few more things:

Your HP limit is gonna be your fuel setup. You’ll need a 535LPH intank and LT4 injectors and HPFP at least to make any decent numbers on E. Or if you are not planning on running E and just straight 91, I would add a meth kit.

 

Also make sure your PCV system have a really good flow. Any positive pressure will blow out the rear main seal. Vent the valve covers to an atmosphere can catch with -10 hoses. And a catch can between the valley cover port and the intake tube.

      Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

      By Policeoff01 · Posted

      Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
