While browsing the forums on http://www.savage-central.com I found a guy who modified a CEN GST CVD to fit a Savage Flux. I followed everything he did and this is what I came up with.

This is how it looks after I was done. I had to shorten the DarkSoul wheels extender about 8mm because the axle pin is closer in compared to the XL axles. I think shortening it is a good thing because it was extending a bit further than I liked. The CEN CVD are real 8mm axles that has a set screw in the middle to hold down the axle pin so I do not need to use the O-Ring anymore. But I use it anyways just incase the set screw gets loose.

Here is a view of the CVD with the steering turned all the way to one side.

I had the change out the Flux diff cups because it was too big for the CEN CVD. The Flux dog bones has a 11mm ball and the CEN CVD has a 8mm ball so there was too much space for the CVD with the Flux diff cups. So instead I used HPI part number 86064. I picked these instead of the upgraded harden steel 86278 because I was told I could harden the 86064 version myself. Plus I found a set of the 86064 diff on ebay for $5.15 shipped.

The CEN CVD fit without any contact to the HPI suspension upgrade kit.

Here is a view of the CEN CVD with the Dark Soul 24mm wheel extenders, CEN Matrix Upper Arms, and Losi 8ight turnbuckle with Savage Rod end.

Here is the CEN GST CVD with the modified one on the bottom.

You can see the silver part where I machined off the excess metal so I can slip the CVD in to the bearing.

The top is the standard Savage Flux dog bone with the XL axle. Look how beefy the CEN CVD compared to the Flux.

The diameter of both all the axles are the same, 8mm. The Savage XL axle will push the wheels out a little further too but the DarkSoul extender will compensate for that.

The stock CEN CVD is about 15.90mm

I took off about 11mm and it seems to fit perfectly.
