Actually, they used better metals on the older trucks. While your truck may look new paint wise, underneath it is rusting away, I can guarantee. It might not look it, but I assure you, it is. I have to use an industrial air hammer to get brake rotors off of anything starting back around '07-'08 or so. I did a brake job on a '18 back in 2020, and that air hammer had to WORK for quite some time to rattle those rotors off. Never seen anything like it in all my years of wrenching. Just 2 years old! If you haven't had problems yet, consider yourself VERY blessed!! You got yourself a good one.

Smitty, is your 2007 Silverado an early 2007 "classic" of the older model or is it a late 2007 new model GMT900? NO particular reason for asking, just curious. They had them side by side for a while on the dealer lots. Pretty sure that the early 2007 models were the last ones that GM offered a manual trans on. Except Mexico market, where they kept going with them.
It's the 900 series. A mechanic would've been able to tell that just from the problems I've had, if that tells you anything. Glaring differences in quality between the 800 series and 900 series. The 900 goes, stops, steers, and rides better, but at the expense of parts quality across the board. The interior of my truck has squeaked and rattled at 2,000 miles, more than a 266,000 mile '94 K1500 I used to own. Brakes were pulsating on the TEST DRIVE!! 40 miles on the clock! The LS engines are all great, BUT, GM ruins them with low bidder crap parts they put inside them - the AFM lifters being just one of many parts. Valve springs break, rockers spit needle bearings into the engine, and there are countless places for internal oil leaks (especially on a AFM engine) that cause early valvetrain failures. Transmissions don't last, and neither do rear end components, unless you drive it like a 98 year old grandmother. The 800 series truck routinely reach 300k miles or more without ever having to go into the engine, and the rest of the driveline will last deep into 200k mile territory.
