RoflCopter726

I just turned 90k miles last weekend on my '07 LT1 ext cab NBS. I've changed the oil and filter every 3000 miles and had the tires rotated every other oil change. I have the 20" wheel package with the Goodyear Eagle LS2's, 1st set lasted 55k miles, and my second set seems to have a lot of miles left to go. I changed my brake pads to ceramics at 80k and turned the rotors.

That's pretty much all I've done to the truck since I've had it. It'll be 4 years in April since I bought it brand new and I've loved every mile in it. I want to keep it in the best running condition possible, so I need to know what should be serviced or replaced. I don't tow, I only carry a motocross bike since I race. I drive long distances occasionally so thats about the only strain I put on the truck. Any help would be appreciated, thanks.
