Hi guys. I'm going to replace my headers soon, so I as wondering what bolts and what size I need. The headers don't come with any hardware, so I need to purchase some - so my question is: What size, type and where is a good place to order them online. Cheers, Indy.

 

Did you ever find out the size and length. Getting ready to install header on my 05 SUT.

 

I ended up buying a set of headers (hedman hedders) that had everything included (gasket, bolts...). I did find the size when I was searching on one of the hummer forums though, just don't remember the numbers, sorry. Anyways, headers are on. Wasn't easy getting the old ones off. Installation of the new ones was easy though. If you need any tips with the install, just send me a pm. cheers

 

If you give me your VIN #, home address, bank account #, SS # and personal PIN # I will be glad to assist you with your question.
