MIP CVD's

[RustlinMan]

What do these do exactly and do they provide an actual excelleration enhancement? Are they worth the money?

[fanman]

They replace the stock slider type drive shafts with CV drive shafts. Some people say that they aren't worth the money, but I haven't had any trouble with mine (I have them on two trucks). If you build them correctly, and take care of them properly they will work fine. As for any acceleration gain, you don't see much, if any.

I have them, they are pretty good. Just remember to put the grub screws on the flat part of your tranny. As far as acceleration goes, they do make a little inprovement since it does have no binding

[jpvitullo]

and don't forget the loc-tite!

I have been using them for 2 seasons of racing now with no troubles at all. Much tighter drive line and better suspension action under acceleration and braking. I would stay with the stock shafts for bashing and go with the CVD's for racing.

whut are CVDs/??

As he said, they replace the axles with a type that's less likely to bind, but if you get the stock axles to bind, the CVD bones will fall of the truck, with the same suspension setup.

I've had my CVDs for about 2 years now and here are some things that have happened to mine.

First of all I did shrinkwrap my CVD joint but still the CVD pin flew out on one side which costed me 3 bucks for a joint rebuild kit (nothing to cry about). So what I did the second time around was shrinkwrap it twice. Hope this works this time.

Second when I re-loctited the grub screws that held the CVD pin I noticed that there were microcracks on the CVD joint cup where the pin goes through. This will become a future problem but you can't expect them to last forever.

You do have to properly "space" the CVDs with teflon washers (part# 1985). I used three to move the yokes out and about three more (+-1 washer) here and there in the bearing carriers to eliminate play.

Drive cups show the normal wear and tear.

I do notice a small difference in acceleration after switching to CVDs but this could just be my imagination.

And to note I run my NR with the rear arms level.

Hope this helps...also look around by doing searches, you will find more helpful hints and opinions...the only thing is at the end you have to try them out for yourself to know if you like it or not.

yeah some people love the cvd's, some people hate them. i personally haven't had many problems with them but that's just my experience. i will never go back to the stock joints.

[tony_250r]

CVD are the only way to go. Once you get them dialed in you'll never go back to the stock set-up.

CVD stand for constant velocity drive.
I regret buying CVD's and I'm porud that I bought them both at the same time. When I installed them into my Rusty I can hit the throttle about 1/4 of the way and let go of the throttle and the car would keep on going with out stopping until I hit the brakes. With other people they said that they would go almost full throttle let go and stear the car around for a long time without touching the throttle, and the speed would SLOWLY decrease till it's speed is equal to idle and at idle the car stays at a constant speed without touching the throttle. It's really cool! I regret buying CVD's because I instaled them incorrectly so it's my fault buy I took trhem out and re-did the installation process and since then I havn't had a problem. Definetly worth buy, hands down!

[traxxas speed1]

i dont like cvd's for 1 reason...The guy that owned the car before i did did somthing to them and i couldnt keep them on my truck(nr) now i like the stock ones because they are stable and strong

[TeamJandyzer]

traxxas speed1, your right on the money. I was sooo frustrated about my CVD's that I just wanted to go back, then I was like, okay lets give it one more try, so I re-did everything, and they work just fine!
