    6mm pivot balls?

    Hi!

    MM you said you have made the Hi-Impacts ready for 6mm pivot ball upgrades. Does this mean they will accept pivot balls with bigger shafts? Or does that mean that you can thread the 5mm hole to 6mm?

    Did you ever make bigger balls(haha) and if so can I buy them?

    And are there no upper racer hiimpacts? I know that the impact force mainly goes to the lower arm so that's fine.

    Thanks!

    I have contacted a machine shop that said they can take the 5mm threaded hole to 6mm threaded for $50-90. Is it possible? Is that price fair for four arms?

    seems pretty expensive to me, and what are you going to do for pillowballs when you get there?

    1. Arrma Kraton BLX carriers
    2. Arrma Kraton BLX stub axle(whole assembly is cheapest)
    3. Mugen pivot balls
    4. Traxxas steel cvd bone only (they are high quality 6s capable) The fit isn't great- you need two shims on the pin inside. I am looking for another option. (Some are out there for sale, or you can have some made)
    5. Drill, drill, tap, tap per side (local machine shop charged me 40 bucks)
    6. ~90-100mm turnbuckles. Your choice.
    7.Arrma Kraton BLX 17mm hexes. Other hexes will do including 23mm but will probably need shims.
    8. Spacers for the Traxxas CVDs I don't know the measurements. But i will get them.

    You can stick with the arrma pillow balls to save $20. Just remember they are standard and are heavier.

    I continue to seek to improve this list and I when I find a better fitting CVD I will post a complete list and pictures or a video.

    There is an aluminum version too of the carriers. Plastic is plenty tough enough with for these but here is the link for some extra bling.CLICK

    i found the missing element. Mugen has some pivotballs for the mbx6 series that shorter and dont have a stop on them. This means we dont have to use shims. Now i just need to find the right cvd for this new length.

    To get here by trial and error i have spent hundreds.
    To copy this setup not two hundred. I will have a full tutorial in the coming weeks. Pricing, links for where to buy and everything.

    Parts, price, place.


    ANY lower 3.3 a-arm. $Free-$50 Mine: FLM lower arms.My choice and favorite for this is FLM arms. They are 6061 t6 billet and I have put them through the paces. Once they took a direct hit on the front tire only to bend to have the lower pivot ball break and the top one bend. True billet, cheap price, plus smart structural design makes them a great choice
    CLICK RC-Monster Store
    CLICK EBAY


    Upper UE RacerX arms. $75-200 Or UE EXT Upper arm. There are a couple on ebay but they are sold with the whole kits. Very expensive. Good luck on finding just the upper arms. I was able to find them. (Thanks Fred!) Old .15 maxx upper arms might work. Now you have to drill and tap your arms. The pivot ball hole at the end of your arms is 5mm it has to be drilled to 6mm and have the hole tapped. A local machine shop charged me $40. They offered to do it free but I didn't have all parts ready. I went back a few weeks later and a sales guy heard about it and made them charge me. You can do it your self too. The tools can be find relatively cheap. Just a tap set. You can sometimes find just the one tapper bit on ebay or amazon.
    75-200 dollars. They are listed for 28 dollars a piece on at UE but they are out of stock.

    Kraton or Outcast BLX front carriers. $20. Make sure they are BLX You can also find them in Aluminum but the plastic is plenty strong enough here.CLICK EBAY
    EBAY Aluminum
    CLICK Aluminum Here is the thing If you buy the carriers as plastic from the chop shop with the pivot balls in them they will be standard thread. You will be drilling and tapping the arms out okay? You will only be able to use 2 of the 4 arrma pivot balls anyway. So I strongly recommend Mugen. The superior pivot balls are for the Mugen mbx5 to mbx7. They fit perfect and are metric thread the best thing is that they are LIGHTER WEIGHT and smoother and the after market offers them in TITANIUM. NOW if you buy the aluminum ones they will never come with pivot balls. Here is what you need to know about the pivot balls:

    Mugen pivot balls $20-50 You will not be able to use all four of the Arrma pivot balls anyway. You need 2 Mugen Pivot balls without the stop and 2 with the stop. The ones without the stop on them go the bottom the ones with the stop go on top. The ones without the stop are getting harder and harder to find. If you can't find them you could dremel or file the stop off.






    Arrma Kraton BLX axles $20-40 EBAY CLICK Make sure you get BLX. You could get the whole assembly You will need the 2 little parts inside the joint. The cvds that we will use don't come with the little parts. If you think you have the parts you can just buy the stub axles.
    It might be better to instead buy the little parts and then the stub axles here they are:
    EBAY CLICK STUB AXLES

    EBAY CLICK LITTLE PARTS

    SWORKZ 330108 cvd shafts. 125mm. $30EBAY CLICK
    Most cvds should do that are 124-126mm in length.

    Arrma BLX Kraton/Talion/Outcast Hex hubs $10

    EBAY CLICK Make sure you get the BLX


    The turnbuckles are up to you. $Free-30 The TRX3.3 112mm red tubes will work if you take off the supplied plate that comes with the Arrma Carriers. I suggest you find shorter turnbuckles and use the supplied plate. I think you will need around 95mm. Turnbuckles are easy to find. You could order shorter turnbuckles and find long rod ends that you could cut to fit.

    There are other things we could talk about. Like if bump steer isn't something you notice or care about you could get the Arrma Nero Carriers and keep your stock or aluminum stock arms. No need to get the expensive and rare RacerX or EXT. This will probably mean that different CVDs will be needed but you can use your Arrma pivot balls without having to get Mugen ones. Just remember when you tap your arms to tap them with a standard tap.
