    So I have an odd question I’ve pondered when debating if I want to keep my 285s or step up to 315s. Either way I’ll be regearing to either 4.88 or 5.29 respectively depending on my decision.

    My question is drivetrain component related - is the 2.7 R156F platform “weaker” than say the 3.5 R62 platform when it comes to adding bigger meats? My thought process is a drivetrain and diff built for V6 power might be inherently stronger than one built for a 4 banger.

    Am I wrong to assume this? I’d be happy if I am. I don’t expect ANY truck to last as long as a stock truck, but I don’t want to add fuel to the fire as I plan to keep this 5spd piece of history until the wheels fall off.

    Just a note, the SR MT should have the same diffs as the MT Sport and MT / AT ORs / Pros. The one big difference is that the SR has 3.909 gears with the MT (see the link in my siggy). You may not need to go all the way to 5.29s? 4.30s or 4.88s might be sufficient.

    I really like this site for playing with that info:

    As far as pure strength, I have no real idea but can't imagine that there is any difference in the driveline.

    After speaking to multiple SR members on here (and my own driving experience with stock 3.92s + 33s), 4.88 for 285 and
    5.29 for 315 is just right for my use. I rather have a little extra gear then not enough - especially when I head up to the mountains where a small NA engine gets choked.

    But yes, my question is about pure strength of the driveline between 2.7 and 3.5.

    Thanks for the link, used it in the past running numbers, it’s awesome

    Cool. It sounds like you have all my info covered. :D

    I do agree that more gear seems to work better than less when looking at the stock differences on the V6 side. 4.30s seem to be a sweet spot on the stock side of things, IMO.

    Totally in agreement, just curious if @downhillbik3r or anyone else with the 2.7 can confirm any of this in regards to drivetrain strength between the two models.

    Strength of the driveline is basically the same as a V6 truck.

    Assuming a 5spd MT
    The R series transmissions are known to handle power and abuse way beyond what a 2.7 will put out.
    The MT models get the new larger, stronger 8.75 inch dif. Front 4x4 drivelines are all the same.

    I agree 4.88s and 33s. 5.29 if going to 35s.

    Hoped you’d chime in, much appreciated sir!

    And yes, 5spd R156f
