Bumping this post by giving a update on my truck
just rolled to 70,000 miles on my 2014 5.3 V8. It has been lifted 6” on 35s since new, I bought with 38,000 miles two years ago.
Matinance has only been oil changes always done at 6k miles and frequent tire rotations. At least every 6k miles sometimes 3k
problems:
The AC compressor went out around 45,000 miles
the transmission coolant line in the front was leaking, replaced like and no issues (68,000)
Alternator went out around 60,000 miles
I got a superchips programmer, which is a must for a lifted Silverado. Truck drives way smoother on the highway as it actually stays in 6th gear going down the highway rather van bouncing between 5th and 6th
also, if you are deciding between nitto trail grapplers versus nitto ridge grapplers, go the ridge. I was on the trail graps for about 10,000 miles and once they wore a little they got pretty loud on the highway. I’m at around 10,000 on these and they are much quieter and comfortable, yet still look aggressive like the trail graps.
ive done a roadtrip to Colorado from Texas with the current set up and it was very smooth and comfortable . Depending on the wind direction, I get about 12-15 on the highway
