grinding cups on the stock shafts?

[ixer]

Is this an acceptable practice to gain some more steering? I'm tapped out, budget wise right now. I just put a hitec steering servo on and I'm extremely happy with. Just would like to use a bit more of the available swing on the pitman ARM.

Thanks, Rob

it does work ok, but I just got some cvd's $30 and its night and day. It cuts out 21 inches of steering in a half circle and thats from the grinding mod your asking about, I believe the grinding only saved me 3-6 inches from bone stock.

Grinding will work, just take it slow - it doesn't take much; shaving a bit off the knuckles where they hit the axle may help, too. It will help steering, as much as your setup allows (ie: your steering knuckles will hit the axle, tires will rub shocks). I just broke a Losi CVD so I did the ol' grinding on the stockers, but because of my chassis width and shock placement, using the after market CVD's or grinding the stockers doesn't help me that much...mileage will vary.

I figured it would help a bit, and I figured id have to do some clearance work on the knuckles also....I want to do aluminum inners, outers, and cvd's but I don't have the funds for it right now....so if I can gain a bit over stock for free, that would for now.

Thanks, Rob

I hear quite a few people break the CVD's so i just ground the stockers down. They are plenty strong and if you do break one they are only about $7 to replace. I am at around 24" for a turning radius. With plastic C's and knuckles.

I'm also leaving the stock tires on until I can get the metal lockers, so I didn't think would have a problem breaking the axle shafts....maybe? Lol...

Do it. Grind away. I'm currently running one side w/ moddified dog bone and other cvd. Works for me. I don't see how these people are getting a 21'' turning radius. I've got some killa steering angle and best I've reach is 26''. Not sure how other people are measuring either.

Your doing it all wrong kiddies

You want to file the cup down about 1/8th to 1/4 inch

Now this is what seperates the men from the boys...

Once its down to size, rebevell the cup... you may have to clearance a few things like your C's, and you diff and it'll turn sharp as any cvds out there...

For extra points, rework your steering linkage

ya i ground my cups down rebevelled the inside edge and cut an angle on the ends of my dog bones and it will turn just as sharp as a rig with cvds an i havent broken one it yet

Happen to have pics?

Thus is a link for some sharp steering setups.

Not sure were the link is for the cup mod but if you search you should find it.

EDIT: never mind, the steering thread is on the first page. Modding stock MRC for increased steering throw
