-- MANTIS CENTER DIFF --

I just finished installing and playing and all I can say is Oh my god acceleration!!! It is dark here so my testing has consisted of some parking lot action and some dirt lot play while avoiding the snow patches but man is this good. I was running a stock slipper with HD pads powered by a Tekin Pro4 4000kv which has never seemed lacking until now. I can see and hear the difference. Under acceleration the front end is lifting to point where it wants to rotate over but the ball diff is allowing the rear to settle as the power transfers to the now lightened front end. The front tires expand under acceleration and tear at the ground creating a great sound on the pavement and some nice roosters in the dirt.

Under acceleration it feels very much like I have an overdrive pulley but quickly balances out and feels very neutral off throttle. Marcus and I talked about this before I received it and he was dead on, it has the advantages of both an overdrive pulley and a non-overdrive pulley. Very NICE job on this upgrade Marcus.

The product itself is a breeze to install and the only difference I noticed is that mine shipped with a 62 tooth spur rather than the 60 that I thought they were going to ship with. Since I already run a 62 it made the install that much quicker. Thanks again Marcus!!
