Engine Size and Year

[Wylie_Tahoe]

Currently have an 03 4wd with 5.3 flex and looking to upgrade by a few years and lower miles.

So my question is, starting in what year, did the Tahoe offer a larger engine? And was it the 6.0 or 6.2? and was it the 6.0 first then the 6.2? And if so, whats the years those engine where offered?

TIA

I presume you’re asking about the GMT900 platform? If so the only Tahoe in that generation that had a 6.0 V8 was the hybrid Tahoe. There weren’t vary many made, and I believe that there was only a couple of years that they were offered. I think 2008-2011.
tahoes in that generation came with the 5.3L V8, except for a handful of 2009 LTZ package tahoes that came with the L9H non AFM equipped 6.2L V8.

Nope, dont want a hybrid. But if if gonna spend the coin on a newer, lower mileage rig, I want the larger engine if there is such a thing. Otherwise, ill put some $$$ in the 03 and keep it.

Whats funny, I bought a new 2002 trailblazer with the 4.2 I6 late in the year model, over waiting a couple months for an 03 with the 5.3. The 4.2 was a stump puller.

What rigs 2007-2014 were non AFM? 6.2 and 4.8 ? Were there suburbans with 6.2 non AFM. If so what models ?

Only the 6.2 was optioned without AFM, but it was only in the first couple years. All 2009 L9H 6.2s did NOT have AFM components in the engine. Most 2007 and 2008 6.2s had the hardware components for the AFM system but it was not activated in the software, with handful of guys I know on here here that have said that their 2007 and 2008 6.2s did not have any AFM components at all. From 2010 and newer all V8s in the SUVS had AFM, with the exception of the aluminum block 6.0s that were offered the in the 2500 series suburban and Yukon xl, up to 2013 which I believe was the last year the 2500 package was being built.

I agree the hybrid tahoes aren’t worth it. The 2009 LTZ Tahoe with the 6.2 is a nice rig for sure. They’re pretty rare though. Hard to find trucks. If you’re seriously interested in a 6.2L V8 you’re more likely to find one in a Denali package Yukon, or an Escalade.

There were a few hundred 6.2 (L92) RWD Tahoe LTZs made in 2008. There were about 600 or so made in 2009 with both drive lines and the 6.2 (L9H). That was it AFAIK for the next generation, a few year newer than yours. There are lots of GMC Yukon Denalis with the 6.2 in either AWD or RWD and every once in a while one of the rare 2010 GMC Yukon XL SLTs shows up with the 6.2 L9H engine.

How about a Crew Cab pickemup? More 6.2s available in late 2009 through 2013.

Didn't the Yukon Denali and the Cadillac Escalade offer 6.0s in the GMT platform? Seems like those would be the go to rigs for 6.0 engines. The Cadillac even had the LQ9.

That would be the GMT800 platform. Which would be the same platform as the OP has now.

That was sort of my point. He wouldn't have to go to the GMT900 -- and the complexities that involved -- because there were GMT800s with 6.0s, with the LQ9 being a really good option.

I thought he was wanting a new vehicle, not a bigger motor???

he’d be hard pressed to find one with low miles right now..... but maybe he does want a newer rig than his platform.

I think he wants both?!

Yeah, I'm unobservant. I originally missed that first sentence. Sorry!

Newer, but not new, but was hoping that by moving up a few years newer, I could also get a larger engine.

So outside of a few unicorns, it seems that the 5.3L is still the engine in the Tahoe? The Denali or escalade may be a trim level im not wanting to spend that much for. Dont need a fancy work truck.

For what I do, I prefer an SUV to store my tools dry and safe, so a pickup is out. Also, the bed of a 4x4 pickup seems a bit high to lift my stuff up and into. The back of the Tahoe is a little higher then my Trailblazer, but manageable.

Tahoe's often command more money than the lessor known Denalis and Yukons because of their popularity. If you're not in a hurry and willing to travel to get one, look for a 6.2 Tahoe from 2009. From 2007 through 2009 the Suburbans and Yukon XLs also had the option of the 6.0 L76 all aluminum motor. This motor had VVT and AFM and is NOT the same engine used in the 2500s. The longer trucks are often less expensive than the shorter Tahoe too.

Good info. Not in a hurry this time around and can likely purchase the new rig without the need to sell the old one before.

The burbs and XLs are too long for me, but agree it would likely be an easier find and at a good price for one with the larger motor.

Yup, unless you can find a 2009 LTZ package Tahoe with the L9H 6.2L, most tahoes you will be looking at will have the 5.3L.

You want a bigger engine because...?

If towing or hauling, a 2009+ with a six speed trans will perform better.

 

[Wylie_Tahoe]

No replacement for displacement, right? In all seriousness, If spending the money to upgrade, why not make a larger engine, if available, part of that upgrade plan? The larger engine is available in the burb chassis and pickup for a reason.

Yes, my truck tows for a living. Are the actual tow specs better due to the 6 spd, or is the drivability just better?

 

[Bill 1960]

The experience is a lot better. Much lower first gear in the six to get a load moving. Closer splits between gears so you’re in the sweet spot between peak torque and hp more of the time. The rpm difference 3-4 is huge with the 4L transmissions.
