  1. Nice truck. Keys are a waste of money. You should have more than enough adjustment with the stock keys. Just don’t go overboard and have the front end aligned after
  2. Lift advice

    Whatever you do, do not use lift keys. They are a joke and the stock keys can be adjusted plenty but wouldn’t recommend it for a lift
  3. Help choosing headers for 5.3 Silverado.

    I’ve looked at kooks, big bucks lol. That is the first I’ve heard about 5.3 manifolds being durable. I also haven’t heard bad about them. Just going off experience with my 454. Not looking for a power increase but wouldn’t mind it. Mainly looking to have a lasting exhaust without leaks. Thanks

    Do you currently run those or have experience with those? Thanks
  5. Help choosing headers for 5.3 Silverado.

    I’m guessing your happy with them. I’m actually looking for oppinions on headers for ls motors but will look into the edelbrocks.
  6. Rear diff

    Check your owners manual. All of that info is there.
  7. Well my Silverado with the 5.3 is starting a manifold gasket leak and the manifolds are pretty rusty. I can’t tell you how many times I’ve changed the exhaust manifolds on my ‘98 454. They always cracked so I have given up on stock style manifolds. from what I’ve read, long tube headers are the way to go. Problem is, I’m not sure which to go with. Pretty sure I want either stainless or ceramic coated headers. Not wasting my time with painted versions. Please give me suggestions on choosing the right headers and some oppinions about how to setup the exhaust from there would be appreciated. Thank you!
