Active Hobby TYPE-C High Steering Suspension Arms

Hi All!

With the trend of Y arms and super high angle steering in both Counter-Steer and RWD setup, I finally had enough and took the leap and purchased my own. But you know me, I couldn’t just get any Y arms, I had to get some pink ones to match my Sakura D3! two contestants were in list: Active Hobby & Overdose. I ended up going with Active since their arms looked a lot thinner than the OD ones (as well as their adjustable CVDs).

Alright I’ll admit it, I’m a sucker for Active Hobby products. But in complete honesty, I think it is well deserved. Their products quality is good, their machining and anodizing is like hot candy, and the functionality of their parts is great. They drop in on the D3 perfectly but do require you to use shims on the arm shaft to prevent the arm from moving forward and back.


I setup mine about 2.5 from the rear suspension shaft retainer (not sure if this is where it will stay though). I also had to scavenge for ball ends from my parts stash since these arms do not bring any (I actually don’t think any brand out there does). Other modification on the list was to use the long shock shaft ends for my suspensions, as the hole location is set lower on the arms. I actually ended up using some Tamiya ones.


Now for the top linkage, this is where you have to get creative. As you may already know, going with this type of setup forces you to also change your upper arms. Why? because the stock upper link does not support your caster angle. The options are to either go for a set of upper arms like the Wrap-up Kondo ones, or the Overdose, or Active again. In my case I chose to have continuity and stuck to Active Hobby Type C uppers. Be mindful of your spur gear, things get tight really quick. A way around this is to either shim you shock tower back, or go for a lower size spur (not recommended as it increase your top end)


 You can run massive amounts of caster this way.


Look at all that carpet fuzz! hmmm Yummy!

After all this tinkering, I was already able to observe crazy amount of steering angle! But it still requires me to do a lot of adjustment to reduce the caster generated by this setup. I also conversed with other D3 owners who claimed that they were experiencing binding which I still have to see happening myself. So far everything moves freely without hick-ups.


After installing everything, I can say that this product will greatly improve my switch from counter-steer to rear wheel drive as far as steering goes, and that it is also a major bling factor on the chassis. I am still discovering new setup with this type of linkage, and I will keep experiencing with new ones in the coming days,  but overall, even though this was intended for DIB chassis, it still fits perfectly on the D3.

Final grade: A-

Even the price is decent when comparing with other brands such as Wrap-Up and Overdose, $34 on Banzai Hobby. I gives this Hop-up A- because even though it looks nice and does what it’s supposed to do, I still think it should bring its own ball end. You can find this item on Banzai Hobby right here, and you can also visit the Active Hobby website for more info (in Japanese).



  • Michael says:

    What parts did you use for the triangular linkage?

    • Hi Michael,
      Sorry for the late reply. I used the pink turnbuckle used on the 3 Racing FF chassis. I bought a few different length to try different combination. Although after a week of intensive driving one of the turnbuckle broke on me. I then upgraded to the Active Hobby upper arms for Yokomo Type C (STR192PI) and their knuckle/CVD combo (STR185PI). I will post a full chassis setup pretty soon for the public to see.
