    Rear driveshaft upgrade

    I just broke the left rear driveshaft on my Slash 4x4. I have been slowly upgrading parts on my truck as I have been breaking them. This has been the first time that I have had anything from the driveline break.

    Is the Traxxas 6252A good, 6252X better? Or is there a even better alternative from a aftermarket supplier recommended?

    Rear driveshaft upgrade

    Sorry to say but I donít know what part number your talking about, I looked on traxxas website and both were non existent.

    Maybe Traxxas 6852X or 6804R.

    But as for 3rd party, MIP or Tekno shafts are the way to go.
    MIP are heavy but are about as strong as you can get. Tekno is what I use and I like them cause theyíre lighter and still pretty strong. Just be prepared, theyíre kinda expensive but worth it.

    If I go with the Tekno M6 rear drive shaft will I need the 17mm adapter?

    If this is a dumb question I am obviously very new to this hobby.

    I use the 6852X driveshafts currently ("heavy duty" driveshaft, supposedly out of the new rustler 4x4? But don't quote me on that). I put them in almost two months ago and have probably 10-15 packs on them with no issue at all. I was blowing through the factory ones every week it seemed like. The only thing with the 6852X is that I had to cut the splined shaft maybe 1/4-1/2" as they were a tad bit long, but that's no big deal.

    I had the MIP X-Dutys on my old slash 4x4 and wasn't a fan... Between the pins falling out and the surface rust, I gave up. Now I have heard good things about the MIP Race-Duty axles, but haven't tried them personally. I've also heard good things about Tekno, but again, haven't personally tried them either

    No problem we all make mistakes.

    No you donít need the 17mm adapters unless you want to add stronger wheels. The stock slash wheels are 12mm hex if your going to stick with them then you donít need the adapters. But I just put the link up just so you knew they existed if you ever went to 17mm hex wheels.

    I put these on my slash 4x4.

    Stronger 17mm hexes and about the same tire size as stock. Work well when Iím running 4s.

    I've been running the MIP X-Duty's on my stampede for almost 2 years. As long as you locktite them and tighten down the grub screws before every bash (takes 30 seconds) you won't have much issue with them. I ran 2S for a long time and 3S the past 6 months. They are still holding up just fine. I was going through stock sliders every other bash on 2S. Got tired of that pretty quickly.

    Welcome to the forum and the addiction! You are among a group of people who share the love of the Traxxas Slash 4x4! If you have any questions please feel free to ask. Remember we are here to help!

    I have been using the same set of MIP axles since July 2011! They have never been rebuilt and I don't perform maintenance on them. If you are looking for something that will last you many years, or something that you install and forget about, MIP X-Duty axles are your best bet! I have a set of Traxxas axles on my newest Ultimate edition. They have held up to the Velineon motor system and 3s lipos like a charm! Bit they are less than a year old. So far so good

    I have broke a ton of driveshafts on my slash. I stick with the plastic shafts because if you upgrade to metal driveshafts your have a high chance of breaking your diffs. If it is breaking on the stub axle where the pin goes through there are stub axles that u can snap on to your old shafts.

    TIP (upgrading anything to metal, will cause some else to break. For Example,if you upgrade your hub carriers to metal, you will break your stub axles.)

    That's all well and good, but when you bust the ears off the plastic ones after 2-3 packs... that gets old fast.

    As for the carriers... if the arms are plastic, they will flex still even if the carriers are metal. I'm all for not running alloy for everything, but for some things, it does help with durability. I'd never run alloy arms or towers if I can get away with it. You need something to give somewhere along the line, that's for sure.

    My slash is upgraded. I drive like a bat out of heck, and haven't broken anything in a while.

    I did melt some solder joints..


    EDIT: Wow, didn't know that warm place that isn't heaven is against the language filter
