Honestly, if you're worried about the budget, I'd skip the pricey immobilizers for now. I'm pretty sure you can get a Viper 3105V 1-Way Security System installed for like $200 total, which is a solid deterrent.

For the cats, don't overthink it—the Cat Shield by MillerCAT for Chevrolet Silverado is basically the gold standard and fits your $600-$800 range easily with room to spare for a REXING V1-4K Ultra HD Car Dash Cam too. It’s better to have a physical plate than just a sensor imo cuz thieves usually just move on to an easier target when they see it. Good luck with the new rig!

Sooo, jumping in here because I totally get that new truck anxiety... honestly, it’s a lot to handle when you just dropped that much cash on a Silverado. I'm a pretty cautious guy when it comes to my rigs, and I’ve always been worried about how these new electronics might react to third-party stuff.

I think I read somewhere that if you mess too much with the ignition wiring for a heavy-duty immobilizer, it can sometimes throw codes on the newer Chevy's, so I’d probably be a bit careful there. Maybe talk to a certified installer before cutting into anything? For your budget, here's what I’d suggest focusing on for peace of mind:

* **The Cat Shield:** Seriously, do NOT skip this. I’ve seen so many people in my neighborhood get hit, and a shield is literally the only thing that makes a thief move to the next truck. It's not overkill at all, it's basically mandatory now, right?
* **Faraday Pouch:** This is super cheap but huge for safety. Since your truck is new, it likely has keyless entry, and people can actually boost your signal from inside your house. I keep my fobs in a signal-blocking pouch every single night.
* **Dash Cam:** I was worried about the battery drain too, but if you get one with a low-voltage cutoff, it’s fine. It’s saved me a few times just having that visual deterrent in the window.

I mean, at the end of the day, you just want to make your truck the hardest one on the block to mess with. Even a simple physical lock combined with the tech stuff makes a huge difference. Good luck with the new ride, they're beautiful trucks! 👍

Ok so I've had Silverados for like 15 years now and I get the paranoia lol. To keep it under your $800 budget, honestly skip the fancy GPS and go for the Viper 3105V 1-Way Security System which is usually under $100 plus install. For the catalytic converter, I'm serious... get a Cat Security Catalytic Converter Shield for Chevrolet Silverado for about $250. It's totally worth it cuz these trucks are easy targets. Throw in a The Club 3000 Twin Hooks Steering Wheel Lock for $50 as a visual deterrent and you're golden! 👍

For your situation, I would suggest focusing on a mix of tech and heavy-duty armor to stay within that $800 limit.

1. Honestly, dash cams are totally worth it if you use a hardwire kit. I've been running the Vantrue N4 Pro 3 Channel Dash Cam with the Vantrue VP01 Hardwire Kit with 11.6V Cut-off and it hasn't drained my battery once. The cutoff basically kills the camera before the battery gets too low to start the truck.
2. For the catalytic converter, look at the Talons Garage 2019-2024 Chevrolet Silverado 1500 Transmission and Catalytic Converter Shield. It's a solid piece of aluminum that covers the whole midsection.
3. If ur really paranoid about the truck being driven off, look into the Ravelco Anti-Theft Device. It's a physical plug you pull out when you park. No plug, no start. It's lowkey the most reliable way to prevent high-tech theft... anyway, hope that helps!! gl!

Regarding what #1 said about "Ok so I've had Silverados for like 15..."

• I totally relate to that feeling of wanting to keep your rig safe without tearing it apart. I’m a bit of a beginner when it comes to truck mods, so I was terrified of messing up the electronics on my new one. I ended up going a super simple DIY route and I am really satisfied with how it turned out. I plugged in a Bouncie Smart GPS Tracker right into the OBDII port. It took me like two minutes and I didn't have to cut a single wire, which was a huge relief for my warranty anxiety. It pings my phone if the truck moves or even if the engine starts. To go with that, I bolted in a Tuffy Security Products Center Console Safe which is basically a heavy-duty steel box for the middle console. It feels solid as a rock and gives me a safe place to stash my wallet when I'm out. Quick tips:
• Buy a Mission Darkness Faraday Bag for Key Fobs to stop people from cloning your signal from outside your house.
• Always turn your wheels all the way to one side when parking so tow trucks have a harder time grabbing you.

Been thinking about your question for a few hours now and honestly even though I’ve been on these forums for a long time I’m still basically a beginner when it comes to these newer truck electronics. When I got my current setup I decided to skip the professional installers and just do it all myself in the driveway because I didn't want anyone else cutting into my factory harness, right? I spent a Saturday morning bolting on a heavy metal plate to protect the underside and it was actually super straightforward even for someone like me who usually just does oil changes. I also ended up hiding one of those little quarter-sized tracking tags in the seat cushions which makes me feel a lot better when I’m parked in the city. Tbh doing the DIY thing is the way to go if you want to stay under budget and actually learn how your truck is put together, but do you think you'd be comfortable working under the truck yourself? It’s way less intimidating than the high-tech electrical stuff anyway (at least that’s what worked for me).
