    What CV Axle Are You Buying?

    I imagine installing a right where a left belongs (or vice versa) might explain things blowing apart after a season.

    XFE gets slightly better MpGs, I think?

    Pulling heavy with 04 2500 non HD?

    Pretty much regardless of whatever else you do, if boxing the rear of the frame helps you worry less, just do it. Bonus: tell us about it so we can learn something.

    Theft deterant system.

    The GMT900 options pull more air; they require wiring upgrades and a stronger alternator. Raising the idle to 650RpM alone may not be enough.

    Theft deterant system.

    If you've an LQ4 and a 4L80E, doubt you NEED a GMT900 pair of cooling fans, although obviously 'more than you need' can't hurt so long as the fans have the wiring and alternator to back it up.

    Theft deterant system.

    Depends on how heavy (and aerodynamically 'draggy') the thing you're towing is, and how hot and how uphill you're towing. Also, there are several electrical fan pair options, for heavy / intense hot towing up steep long hills you'd need to research GMT900 electrical fan pairs with upgraded...

    Theft deterant system.

    Electronic signal throttles don't really react. They send signals to the pcm / ecm, and based on a bunch of other info, pcm / ecm DECIDES whether or not, and how quickly, to eventually do with the throttle what you did with your foot. Luckily in the vast majority of situations this can be tuned...

    Theft deterant system.

    After over 30+ years of pcm tuning, even I'm never quite sure of what a competent & thorough tuner means by a 'traditional' tune, if only because the term 'traditional' still discourages those who think that even a basic mail-order tune is for 'non-conservative' or 'over & above' normal driving...

    Theft deterant system.

    If you merely settle for GM OE, it'll 'run right', but it'll also be plug&play if you buy it from pcmperformance.com, UNLESS you ask for a tune. There are such things as 'conservative' tunes, by the way, although you'll still notice improved throttle response from the engine & transmission...

    Theft deterant system.

    If you're gonna buy a new pcm, [email protected] but you ought to be sure that the pcm is your underlying issue; don't use pcms for diagnostic puropses.

    Lesson learned - GMT900 Regret, GMT800 Reset

    By that very same logic, a 3.9L LZ9 or LGD would be even better.

    2025 colorado/canyon wheels on our gmt800s

    My HOPE is that, with a bit of grinding, I'll be able to use RD6 17" steel wheels with the GMTK2 13.5" rotors & 4piston calipers.

    Keep driving your GMT800s?

    Being cheap@$$ isn't very good for their financial stability either. Pinching pennies too hard has lots to do with why the L87 is another QC blemish on GM's reputation.

    2005 cruise control

    Their quality may not be any better, but at least when it fails you get far less hassle exchanging it for another one.

    Intermittent PITA, Intermittent ignition switch or door latch/actuator?

    Percussive diagnostics & quality assurance should never be overlooked.

    Were I you I'd adjust the alignment as follows: *MAX possible Caster. *Slight -Camber, No +Camber. *Slight Toe IN, No Toe OUT.

    Lesson learned - GMT900 Regret, GMT800 Reset

    Aside: there's a thread about short -lived L87s that does not seem to understand what you're getting at here. I'd grant that a 4.8L with 4.10 will likely live an easier / longer life than one with less advantageous gearing, precisely for the reasons you cite.

    Lesson learned - GMT900 Regret, GMT800 Reset

    4.8L 5.3L 5.7L 6.0L 6.2L & 7.0L pretty much all take up the same external physical space. Although the 6.0Ls that mate to the 4L80E do have a different bellhousing bolt pattern, they take up the same amount of space as the 6.0Ls that mate to the 4L60E.

    Lesson learned - GMT900 Regret, GMT800 Reset

    If a 4.8L & a 5.3L are doing the same amount of labor, even if the 4.8L has equal gearing as the 5.3L, the 4.8L would be under a higher relative load vs the 5.3L to accomplish the same amount of 'work' as measured from the outside. The 4.8L in the above example would spend less time in 4th, and...
