I've been lucky with mine i'm approaching 200k miles on it not quite sure if they are Castech's as I never pulled the valve covers to check if they are then they are the better of the two heads from what I've read I have 862's vs the 706's!
Just some common things that go wrong on these rigs they are great rigs just some common things however
the two biggies Tranny & water pump
some other common ones
cluster gauge
Master power window switches
Air bag sensor
All 3 of these I replaced on my Yukon
Just a quick note as I’m not sure where you are located but if you are in a rust belt state such as myself really inspect the under carriage of the vehicle for rust if you are not chances are the vehicle for the most part should be in pretty decent shape rust/rot wise dealers do a good job of...
Ok thanks I knew for sure 3:42 was standard and 4:10’s were an option I did not think 3:73’s were an option!like mentioned however my friend did call GM gave them the vin and they told him it was equipped with 3:73’s so I’m sure that’s the case thanks
Guys have a quick question for you were 3:73 gears an option on 05 Z71’s I thought 3:42’s were standard with an upgradable 4:10 gears.
the reason I ask I was told that an 05 Z I’m interested in has 3:73 gearing as per GM I don’t have the VIN but the guy I’m getting the vehicle from(friend) he...
Still on the Hunt sorry I have not posted in a bit still searching I looked at the 09 Yukon it was at a dealer they just wanted too much for it for a vehicle that was just ok!I did have a couple of prospects my buddy still has the 05 LS my true Love is a Z71!if I were going to go with that year...
You can also contact GM with your VIN and ask for a build sheet they will gladly give you one that’s what I’ve done a few times before going to look at a vehicle just to see what they were equipped with coming out of the factory.
you can email them as well

Another Castech head question!I’m on the hunt for A NBS Z71 I’m looking at years 03-06 I prefer the higher gears in the 03/04’s as I want to run 33’s and almost all the ones after 04 I see have 3:42 gears though I’ve read the 05/06’s are the best of the NBS lot!
my question is with the Castech...
Thanks Ron you guys are great on here I’m sure I’ll be on again real soon as soon as I can track down another potential they are tough to come by but I’ll keep plugging away!
I messaged the guy with the Tahoe telling him I’m passing on it after I got the car fax I’m yet to hear back from him...
Well the Hunt continues the vehicle I was going to look at is a no go,I just got the carfax back from my friend and it appears the odometer was rolled in 2019 from 170k down to 120k oh well I'll keep looking better safe than sorry!
Wow thats clean ,I thought my Yukon was clean you would never find something that clean here in the Northeast!The Northeast kills these great Rigs with the rust.
The Beltway of Doom for any vehicle they rust away before the engine fails!
Yes indeed that is the problem with these Rigs in the Northeast the vehicles rustaway before they go mechanically I'm sure I have room to move on the price a bit any Rig I find here in the northeast are going to have some signs of rust somewhere I or I should say my bodyman will help me diagnose...
