    Just got here. I recently acquired a 94 Sierra 1500 2WD with a 4.3L V6 and 5spd manual trans from a buddy of mine.

    Just bought a 2022 Gmc Denali 1500. I wanted to put 3.5in level in the front and 2.5 in the back. After reading in the forum I’m starting to think that’s a bad idea since most people don’t recommend and level over 2.5. Does anyone know the size lift and spacers I would need to comfortably clear 35s?

    Whenever I go to start my truck it will try to turnover for a while but won't turn on. After the second or third time it will but it is not instantly. Seems like the problem is progressively getting worse. What could this be and what should I check for? Truck has 255k miles. Thanks!
