    Missing sway bar bolts. Anyone know what size they are?

    Swaybar is a huge 3/4" bolt with a 1 1/8" head for factory set up. Bextreme04 I would also highly recommend the ORD Kit if you have any lift between 1 1/2-4"

    2.5" or 4" Lift 1986 K10

    ORD also has 1" Zero Rate Add A Leaf Axle location can stay in the same spot, or you can move the axle forward or backward 1" or 1-1/2". These were perfect when my rear axle needec just a bump up

    Time for new shocks. Look at these!

    I would agree. Depends on what you’re gonna do with this vehicle if it is going to be a street driven vehicle but also taken off road Bill‘s 5100 or 5125 series cannot be beat for the price point if it’s gonna be driven 99% of the time on the street, go with the Skyjacker or any other hydraulic...

    Factory Seats; Why do they suck?

    Personal preference European seats in general are smaller tighter fit. American trucks Tahoes are larger I happen to Love my tahoe 04 and 12 seats drive from CA to Utah Colorado etc back feels great no issues. The angles for me are perfect the way I set up. My Toyota tundra seats at work give...

    What to replace while doing tie rods?

    I know you already purchased parts, I made the mistake by buying AC Delco Gold/professional parts they were cheap chinese and had play in them so I had to do my front end twice stick with OEM AC Delco or Moog. If you havent installed yet
