## Questions & Answers

**Q: Will this upgrade fit older model 2x4 granite "non boost" model??**
A: Yea

**Q: Is the center drive shaft that comes with it long enough to fit in a long wheelbase chassis? Like for the Arrma Big Rock?**
A: It will not. It will be too short. Go with metal as the torque in the Big Rock will be too much and it will break after a short while
