This is what you gotta do to have a lifted truck and still fit in parking garages. I dont think its dumb to have to trim. It's kind of what you get for being a gm fanboy. My friend with a Ford has 35s on a level and I'm jelly. But not so jelly I'm getting a ford. F that. Thanks for the vid. Getting some forces of your website soon🔥😎

[@apg0014]

uhhhhhhhh. ok.

[@humbertocantu1986]

Thanks so much for this video. I showed this video to the guys at Mike’s Truck Toys in Pasadena TX and they removed the rubbing issue on my 15 Sierra with on 35s on a 3.5” lift. 👍🏻

[@alexcardenas3244]

They cut your bumper as well?

[@humbertocantu1986]

@@alexcardenas3244 No sir they only cut the back side of the inner fender

[@diegogarcia-hd7bg]

I just put 35's on a 3 inch level on my 12 sierra, need to cut for the mean time before I do the 4.5 spindles, how bad do you rub now?

[@IsaacLop2011]

How much did they charge you?

[@anayacar000]

Watt the fucc are u doin to my truck is what I'd be thinking 😂

[@nyxzus]

VERY nice trim job. Trimmed my '09 silverado with my plasma cutter to fit 12 wides on a leveling kit, no regrets.

[@tommypearson9260]

I had a Trim job that was great but a few people who have no idea was saying dumb shit like they took a blow torch it's like this is what they had to do to mine but not to the metal just to the plastic

[@creolekolbytv]

Bout to do the same on mine but I’m putting 2 inch spacers on 12.50s

[@youandyourself757]

This video answered all my diy questions ..except my truck is a 2016 z71 silverado...the set up is the same ( 6" RC lift on 33x12s toyos) very smooth but want to get 35s

[@RileyMy5090]

Thanks for this video I was able to make a little more room on my GMC 2500 ! Only video I could find for a 2017 gmc!

[@dannyrap1147]

Looking to put on a 7" McGaughys with 20x10's and 35's on an 18 Silverado. Am I looking at much cutting? The McGaughys listing on your site says it should fit, but you never know...

[@CustomOffsetsTV]

At the most you might have to do some minor trimming but that shouldnt be a problem fitment wise.

[@gasolara2002]

Well I say you got to sacrifice to go with wide wheels. I think it was a great job.

[@Readmypost]

This is painful to watch

[@sawyerbennett8227]

read mypost no kidding I couldn’t even watch it

[@MuySalado21]

Got the same truck and lift on some 24x14 on 35s. Can’t even turn my wheel a full turn. Looks nice though😂

[@That92OBS]

If you ever get a chance, can you do one on a 88-98?

[@TRILL57]

Victor Allen I asked a while back they just replied with keep trimming until it doesn’t rub. I trimmed my truck a while back to fit 35’s.

[@denniscoker6369]

I had to do it to my 76

[@craigquann]

Would I have to do that with a 2 1/2 lift n level with a set of 33"× 11-12" on stock 17" rim? It's a future project for off road use so I need to make sure I'll have zero clearance/rub issues...

[@artygo123]

I have a 2015 on 33 11.5 20 or 295 55 20 i believe with leveling kit very little rub when backing and turning wheel full crank. Other than that it's all good.

[@MrSdbmgarcia]

No one has asked the question.... With this NorCal job, How much space remained when the steering wheel was cracked all the way in the front and the back?

[@CustomOffsetsTV]

about an inch or so, just enough wiggle room to clear!

[@MrSdbmgarcia]

@@CustomOffsetsTV thank you. I'm doing it right now as I type.

[@wesleyarnold6018]

Man I’ve been watching your videos all day. Even read some comments. What I learned from all these videos and comments it’s basically only about looks . Is that correct or I’m seeing it differently. Here in Louisiana if you put on Mud Tires then you’ll be bogging in the swamps immediately. So not just for a “cool” but mostly aggressive looking and Will perform aggressively. Like Interco / Super Swamper tires.

[@Jswans0]

@custom offsets how much do you guys charge to do the NorCal mod??

[@jordan089621]

Jordan Swanson I am wanting to know as well

[@Dr_Snickerz]

Literally just did my own today. Not too bad to do it yourself. Didn’t find a decent tutorial until after I finished and was wondering if there was a way to trim more and keep the outside looking oem.

[@ZachManZ71]

Can you guys do this to my 2014 Silverado LTZ Z71 1500? Thanks

[@enlightment4747]

That was Crazy. I'm not sure that I could do it. I love the 6in lift on that GM though.

[@jaluco02]

Would that apply to a 2014 Chevy Silverado 1500 as well..?? I have a 4” lift up front running a 22x14 -76 on 305/40/22 Zeta Imperó tires

[@Jvrfitness92]

I have a 2015 gmc with 35x12.5, 20x12 wheels and it only rubs on driver side? Any suggestions

[@mattward330]

Can you guys show a Norcal mod on Denali 2500hd with leveling kit or even stock height and 35's?

[@kaleba5443]

Couldn’t you add a few washers to the front bumper brackets to push it out a little more then remove the metal bracket behind the wheel well to push it back further and wouldn’t have to cut the front bumper?

[@CustomOffsetsTV]

Could, but it starts to look like a Jay Leno chin!

[@kaleba5443]

Custom Offsets ok thanks so much.

[@willdamian1066]

What do you guys use to prevent rust?

I have a 2016 ram 2500 4x4 have a zone off road 5.5 lift going on what would be biggest rim and tire to go on it? I am looking at 20x12 with 35 or 37 x12.5 tires with out cutting which would be best?

[@baxford2013]

Rod Murphy 35x12.5 on a 5.5 in lift you’ll clear for days . Dodge has some of the biggest wheel wells I’ve seen people run 35x12.50 on a level kit with no trimming and only rub backing in and out of driveways . Hell on a 3rd gen 1500 with a level kit 20x14s and 33s you barely rub. I’ve seen it first hand

[@SuperGorilla68]

I put a 6 inch on my 16 Silverado doesn’t matter that it was a rally 2 just stickers still looked cool. lol had to butcher it to fit 35’s 22 by12. Couldn’t even turn the wheels stock.

[@501frosty6]

Im possibly getting a 14 sierra, the setup ill be doing is a 7 inch fts on 22x12s and 35 amp mud terrains or all terrains havent decided do you think nearly this much will have to be done?

Nice work and nice truck! How much does this cost to have done?

[@CustomOffsetsTV]

Almost every shop rate is different, however if you are interested in having us do your NorCal mod, send an email to [e-mail] and they should be able to get you a rough estimate!

[@ricardomoreira2689]

Should've done a bigger lift! 7-9in

Ricardo Moreira I'm with you on that one. For sure

[@MidnightXAlchemy]

Ricardo Moreira yep

[@joegraney1]

I did the mc mcgaughys 7-9 on mine and set it to 8" and still have to trim I'm running the havok h109 22x12-44 on 35 its hits when coming out if the driveway or making a full U-turn

[@apg0014]

finally someone with some sense

[@Cmanns05]

Still have to trim dude. Unless the wheel clears the well at 10+ inches you have to norcal. Part of the game. Pay to play

[@avgasandcopwatch]

I did this and I cut my sidewall on one side. I'm not mad. I don't have a grinder getting a harbor freight cut off tool and a dead blow and going back in there

[@frankyq21]

Cutting off pinch weld probably not the best idea. Get some rust in there and that’s separating real quick. Should slice the pinch weld instead. Then bend it back. Spray painting it black instead of white?

[@hacksawjimthuggin7411]

Agree completely.

[@KINGx19x]

Have you guys ever installed extended fiberglass fenders instead?

[@CustomOffsetsTV]

Not in this specific shop, but some of us have outside of the shop on personal vehicles/prior jobs!

[@jeffgoodson9263]

Could you not make a bracket for the front inner fender well to screw to instead of zip ties. Zip ties aren’t very professional to hold that in place.

[@GarageLife]

Good stuff as always!

Ill be attempting this soon on my new denali hd. Leveled gonna try to fit 22x14 on 33s 😨😨😨😨😨

I see a lot of guys doing this to clear mine is a 15 silverado no lift and 33 no trimming will rub woth new tires but only on driveways now I plan to go 35 soon I know ill need to cut but don't know why everyone is having to lift as well mine dodnt need it one want to go long travel fiberglass and 40s but $ is holding me back right now

Since y’all are so good at replying (y’all even reply to dummies like me) I have done my best to do research on this and talk to people on their build and I have gotten answers but not enough to conclude what I want to do to my 2011 duramax. This is what I want: I want to get the tis Offroad 544bm’s 20x12 and put them on 35x1250x20 tires without having to lift my truck more that 3 inches.
