    Here are the parts needed to convert your RC8.2 from bellcrank to swing rack steering

    ASC89075 - Steering Ballstud
    ASC89235 - Factory Team Aluminum Steering Rack
    ASC89072 - Steering Turnbuckle, 4mm (42mm) or ASC89268 - Steel Turnbuckle, 42mm


    You can also use ASC89526 -Turnbuckle, M4 x 50mm but you will have to cut them down to 42mm

    I got all the parts, put it together. My turnbuckle kept popping of when I drove it. Used all new parts including new plastic ends. I also was curious on the length of the turnbuckle for set up. Stock setup was way too much toe out. Any help would be great.

    What are your impressions about the swing rack?

    Thanks for those numbers, I had the 89235 and 89072 parts, but was wondering what else I needed since the angle was too severe at the connection point at the steering knuckle and rack ends, causing them to bind constantly. The 89075 ballstuds are basically an elongated version of the stock 89077 ballstuds and fixes my problem with binding.

    The elongated ballstuds worry me though...the stress on these parts is fairly high and by making them longer, it gives the tie-rod more leverage. Has anyone had any problems with the longer ballstuds breaking under the stress?

    Also, the 89075 package comes with 4 ballstuds. Am I to imply that they should be installed on both the steering knuckle end as well as the steering rack end, or just at the knuckle?

    Thanks!

    Kevin

    Kevin I put the steering on my buggy with the parts listed and I kept popping of my turnbuckle. I was running at full droop and once I changed the droop everything works fine. Look up the manual on rc10 site for the rc8 and follow the instal section and you will be set up just right

    @AERacer
    I havent seen that, it looks like I have to use 89235 with the 89070 set. So the 89235 rack must be longer then what I have in the car. Must I take the 89075 too ?

    Thanks AERacer, you are right, the difference from the inner points where my stering turnbuckles are mounted now to the outer 3 holes is about what my titanium turnbuckles are to short. AE should mention under 89070 that its only working with 89235 and 89075.

    Are these part numbers correct for my conversion? I'm wanting to do this on my Tekno V4 SC8.2e. ......

    Thanks

    Anyone any idea?
    89075 has two short and two longer ballstuds. Where should I mount the longer ones ? They seem to be too long .:(

    Short ballstuds attach to the swing rack and the long ballstuds attach to the steering arm on the castor block

    You need to place 1.5 mm or 2mm shim between the ballstud and steering arm.

    yes, its about 2mm, is it better to him it on the upside of the upright or on the downside before the nut? Im also thinking which rods I will need when I do the same on the RC8T , maybe I will buy a Lunsford kit but then I also must try to get the shorter ones.
    Not easy :rolleyes:
