Canadian GM Guy

Where do you live? Up here in BC Canada I ordered them through Lordco. Lordco has exclusive rights on AcDelco and can order OEM parts from gm through Delco. Sent from my Samsung using Tapatalk

Thanks for the input everyone. Here are the benefits of each as I see them... OEM: FNC coating (anti corrosive as hell but that's about it) AcDelco Severe Duty: Maybe not be as anti corrosive but should handle heat more efficiently and warp less because of the metallurgy Does anyone have any other suggestions I should be looking at?

I'm very torn on the one hand you have the OE ones that are FNC and "durable" and on the other you have the severe duty rotors that are supposed to be better for just that.... severe use. Sent from my Samsung using Tapatalk

Can't, they're below GM specified minimum thickness. Sent from my Samsung using Tapatalk

Hi guys, feel free to move this thread if it's in the wrong topic. I need rotors for my 2017 Silverado, my current rotors have 107,000km on them and are starting to pulsate. As the title states, should I go with the OEM ones with their FNC (feretic nitrocarburizing) process which I must admit are incredibly durable to have lasted me over 100,000km. Or the specialty units which supposedly are made by raybestos and have a higher carbon content in the metal to absorb and dissipate heat but no FNC corrosion resistance. I now live in a mountainous area that's not by the ocean and has pretty minimal rain fall, however in the winter time calcium chloride is used prior to snowfalls. Winter is fairly short lived and snow is minimal now where I live unless I drive the mountain pass. I drive it like I stole it and use my brakes hard. Advice??? Sent from my Samsung using Tapatalk

I looked into that, not for me, I still want the light sensor to function properly. Sent from my Samsung using Tapatalk

That's the goal! And tell me about it, we have that problem here too, Asian vehicles are the worst culprits because the gauges stay lit and the DRL's light the road so you don't even see them from behind on a dark road. Even worse is the people that think they need their brights on in the city. I plan on getting some LED reversing flood lamps in my rear bumper, they'll double nicely as a deterrent for anyone who's behind me with their brights on [emoji6] Sent from my Samsung using Tapatalk

I have tinted windows and the daylight sensor isn't sensitive/or too sensitive so my auto headlights come on when the suns still up and I'm wearing sunglasses. All of a sudden my gauges aren't readable and my nav screen goes into night mode. I'd like to be able to just flick out of auto when needed until it's actually dark out.

Dude you're a life saver! Sent from my Samsung using Tapatalk

Chris, as my truck is a Canadian spec I cant turn my headlights off at night. I read that you guys can fix that but I don't see that option listed in your original post or on your website. Is that something that can be added to the package you're offering? Sent from my Samsung using Tapatalk

Holy! I can't believe they actually had the potential of exploding. Sent from my Samsung using Tapatalk

No I have not had the work done yet. Do you have pictures of your rear window? I'd love to see the carnage lol Sent from my Samsung using Tapatalk

Just an FYI for everyone to get their trucks to the dealer to get this done, I don't know about my friends south of the border but it's fully winter here and I miss my rear defrost. Also note that the recall # and repair may differ for anyone in the States as this applies Canadian trucks only. Mods, feel free to Sticky this if you feel it warrants that. GM Program #: N192270330 Date Issued: Nov 08, 2019 Program Title: Rear Window Defroster Thermal Events Program Description: Certain 2014-2019 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a power sliding rear window (RPO A48) had safety recall #N192220470 performed. This field action restores the rear window defrost function. Repair Description: Dealers will replace the buss bar covers and the contact cover, and for certain vehicles, will reprogram the HVAC calibration to disable the rear defroster from automatically turning on at keyed start. Please note that the rear defroster will automatically turn on during remote start or by pushing the manual button and is not affected by this calibration. If the rear window or sliding glass assembly appears damaged due to an occurrence of high electrical resistance on the rear defroster circuit, they will also be replaced. Dealers will also install the rear defroster fuse that was previously removed in field action # N192220470. Sent from my Samsung using Tapatalk

Where do you order an FSM from? GM? Or another 3rd party company?

Thanks and yeah you're right they do suck. I plan on getting some better gear to test with down the road, thanks for the suggestion. I have a Haynes manual but I don't think it has a lot as far as wiring diagrams go, I'll have to check in the AM.
