    Question Any aftermarket chassis?

    I snapped my KB Rally in half, breaking the chassis, rear bulkheads, center skid plate, and a rear arm. I'm very new to this 16th scale thing. Are there any good aftermarket chassis out there that I should upgrade to... or should I just get another stock one?

    The only "upgraded" ones I know of are Integy... aluminum and carbon fiber.

    What most have done... stuck with the stock chassis and added a few aftermarket parts, like a TBone skid set and/or aluminum bulkheads.
    Whatever it is I just said... I could be wrong.

    I see that the breakage I experienced is pretty common. I assume the aluminum bulkhead would hold it together a little better? Same thing with t bone skids? Or are they for a different purpose?

    Both of these parts help hold the chassis together better, among other things.

    Can you please tell me what you'd do? I'm SO unfamiliar with this platform and have NO idea what direction I should be heading in. Durability is #1 for me, as this is my backup vehicle so that I always have something to run when the other beasts are broken... So I obviously want almost no downtime. Performance is #2. It's got to remain fun. Price doesn't matter if I can get the other two. What would you replace, and with what would you replace it?

    I personally do not like the look of the TBone... if my chassis broke, I would replace it with stock and get a set of aluminum bulkheads. I would shim the differential as I assembled. I would replace everything but the arms with stock. The arms would be replaced with RPM.

    Shimmed diffs? I assume that's to make them limited slip? Would that help with control and prevent the endless spinning out? I don't want it to hurt my drifting.

    Shimming diffs help keep them from stripping out.
    If you want more limited slip, you need heavier differential fluid.

    I'm not worried about limited slip. I'd think it would hurt drifting performance. I'll have to check that thread out.

    no the closer the diff is to locked the better it is to drift
    reason being is that during driffting the wheight is lifted to one side and the other side is lighter
    there for the lighter side will let the diff do its thing ...and spin out
    for every time it diffs out you lose your drift or drifting ability specialy in the front end
    when one wheel could be off the ground...cuaseing the contact wheel to get less power and stop
    there for making it a pivot point in the midle of a drift


    hope that helps tt

    Interesting. I would have thought that a locked diff would keep it from drifting.

    What brands make them? Anyone other than integy and HR? I'm trying to find one for less than 68 dollars lol. Paying an extra 1400% for questionable aluminum parts isn't really my style.

    They are not cheap! No matter what brand.

    Integy actually did not screw this one up... they seem to be holding up rather well. GPM also makes some, HR as you mentioned... not sure if there are others or not. I know at one point in time Toyz had a $100ish special going on that included front and rear bulkheads along with a transmission case. The case wouldn't add a whole lot of strength, but the aluminum would draw a lot of heat out of the motor.

    I'll make something myself if they all cost that much. I was expecting it to be in the 10-30 dollar range like most other parts. I thought 60 was a lot for the FLM trans case on my Rustler!
