will these headers work on a 2001 GMC sierra 5.3 4w drive?

Yes they did fit bit they did not send all the parts that went with it all had hell trying to custom make my flow of air from my headers to my intake because on a stock motor the bolt is on top and on the headers it's on the side and when I called in no one could help me I will never order again from them and the part I am talking about is MY EGR VALVE

Im sure they would work. I have mine in a custom box as well build for my Ram 1500 and they bang :)

All I can say is that it works great on my 1998 GMC Sierra and I love it. Easy to use.

This will fit the GMC Sierra. Its a far better connector than the stock unit.

Should fit. I installed them on my 1999 GMC SIERRA extended cab 3 door 4wd. They went on ok there was just a tab I forgot to bend over so they made noise when I drove the truck until I took them apart and found it rubbing, they do not come with any instructions but most of it make sense just looking at them.

Yes, these would work and I would suggest spline drive or acorn lugs. Thanks Mike 224.587.9255

I checked the tekonsha cable wiring ... already in my 2006 GMC Sierra 3500 ... And the wiring was the same, so yes, I used the same connector that I had been using for the prodigy and it worked fine. The other wire just hooks into the car diagnostic OBDII port

I do not know if they fit 2007 GMC Sierra. You should be able to input your year, make, model to determine if they fit.I put them on a 2012 Chev Silverado.

I have these installed on my 05 sierra 2500HD. They fit just fine. It is tight getting all of the control boxes stuffed in behind them but is very doable if you take your time.

I have them on my 2001 gmc sierra they are the same style as 99, I used the same hook ups and bulbs.

I installed it on a 2013 Sierra so I am not sure why Amazon does not say its compatible.

1988 C/K trucks came with an air pump and tubes to the exhaust manifolds 1992 and up do not. These headers have no provisions for the tubes. The air pump robs horse power and a lot of people take them off. If your is gone or if you plan to eliminate it. Then yes these headers will work fine. Keep in mind, as with most headers, spark plug removal will be tight and factory spark plug wire brackets might not fit correctly. -Barry

I believe the headers are the same as my 2012 Road King and should slop on with no problem.

I have a 5.3 gmc and it worked on mine you will also have to have the jumper wire because it has a different plug on it.

Umm I'm not sure! I know the Sierras and Silverado have different lights but all your doing is connecting the plug, you just have to make sure the two screws are in the same location!

I bought and installed these on my 1990 GMC Sierra so I don't see why they won't fit a 98 chevy silverado.

I would assume that it would. It worked perfectly on my 2003 GMC Sierra 1500, which also had no heat and no signal
