New From Ct

[Rons05z71]

Hi all- New here from CT, and wanted to get this first post out. Just bought a 05 1500 Z71, dark green, Extended cab. I am new here but not new to the forums, some of my previous forums were 2000montecarlo.com and trailvoy.com. This is my first truck so I have been doing alot of looking around on the web for different items. Alot is trying to figure the truck out and what is has. Going from the RPO codes it looks like I got the G80 rear end with 4.10's, I know its got the 5.3L.

My big questions are

143.5 wheel base means its a short bed?

How do I know if its a HD? I have seen several websites ask if you have the HD?

What are the good mods? I think I can figure out that the resistor for the IAT is waste of time and money. But which intake? does it even matter? Why long tube headers over the shorties? Etc, I am going to search around the website but usually people know what works and what doesnt, and I am pretty sure some of you are going to be really knowledable on these trucks. Thanks and inadvance and once again Hi.

Hey there and welcome to GM Trucks!

 

The easiest way to know if you've got a shortbed is to grab a tape measure and measure the length of the bed. IIRC the short bed is 5'9", regular bed is 6'6".

 

I don't think your truck would be an HD given that it's a Z71, but I could be wrong here.

 

As for intakes, lots of threads on here and the search feature will be your friend. Just IMO they all are pretty much the same aside from looks and price.

 

On the headers, others can answer better than me, but IMO shorties are of little benefit performance wise. If you go long tube, you should also do the full exhaust system as well. IE true duals with an X pipe.

Welcome aboard. If you're truck is a 1500 ext cab, it's not an HD...HD was what they used for the 3/4 ton trucks and up. The 1500's are basically 1/2 tons.
