35's a little differently on a gmt-900


Recommended Posts

So the time has come to lift my truck. Its an 07 vortecmax CC in black

 

I started working at an offroad and performance shop a few months back, I sell lifts everyday and drive my truck which only has a levelling kit. Just ordered my wheels today BMF SOTA's 20x9 in death metal finish.

 

I will be running a BDS 4" High clearance and Bushwacker cut out flares for a little more wheel well opening and plan on stuffing some 275/65R20's or slightly larger in there. Later I will get a trail ready, fabfours or road armor bumper if I cant get enough clearance from the stock bumper

 

anyone ever done this before? I know the usual way to run 35's is a 6" lift and still requires fender trimming. This wont work for me since I dont want to sit that high it will make it hard to get the motocross bikes in and out of the truck.

 

either way I will be running this combination I just need to decide if I want to get the Fox Coil overs or run regular shocks in my truck and figure out if the truck needs balljoints again at 87000kms

you could have a body shp neatly cut out the metal on the backside of each fender, then cover it up with the flares.... OR instead of buying fender flares, get some fiberglass prerunner style fenders and trim those to get the tires to fit.

Thats why I am running cut out flares, they remove and inch and a half out of the wheel well and then cover it up. The 275/65r20 works out to a 34.5 and just over 11" wide same as the stock tires I am fairly confident it will work if I have rubbing issues in the front it will most likely be from the front bumper which I am not scared to cut or replace with a trail ready, fabfours or a road armor.

 

Later this month we are doing a 2011 rcsb chev with a 7" -24 offset cut outs and 36x15.5's

 

my truck rubs right now with its stock 20's and 275/55r20's and with its 265/70r18 winter tires and wheels

 

by trying new ideas we discovered you can run 305/55r20's with cut outs and a 1.5" level on wheels with 0 offset like my sotas will be

Your rubbing with stock diameter 275/55/20's? That doesn't sound right. They clear with stock suspension and you have a 2" level kit which should allow you to even run a 275/60/20. I run 275/55/20's and they are no where near rubbing.

I can tell you from expierience to go bigger then 275 65 20!

I had an 06 CC LB sieera d-max with 2-3" of lift and had 20x8.5 rockstar rims with wrangler at/s "silent armor" And i regretted it everyday!! They looked way to small,not so much hieght but the width, They just looked stock and to small under the truck..

Remember they came stock on certain yr f250,s..

Just wish i would have gone with 295/60 or 295/65,s

Just do the research and measure before your not happy with your finished product.

Good luck

i've had many lifted trucks and 99.999% of people that go with a kit smaller than 6" regret it VERY fast. i would definitely consider the BDS 6" instead (almost the same price too). also i've heard from several sources that BMF has stopped production on ALL wheels due to QC issues. my BMF's are less than 2 months old and have LOTS of oxidation on the machining.

    • First off use it in the way you’re more comfortable. In working in off road situations most of my life I used 4WD low range very little. In most cases when equipped I used auto 4WD. If I wanted maximum control going up and down very steep terrain  I used low range. Especially if I was driving a diesel. Same with very rutted terrain. In very muddy or snowy conditions I wanted momentum so high range worked well for that. With gravel ramps with limited traction I would try high range first. I would want smooth even increasing speed if I was fighting traction. Low range could give you too much to the wheels breaking traction trying to move. 
    • Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.  
    • Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.
    • The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts. 
    • I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.
