100665S Vented Clutch housing for your Losi 5iveT, 5ive-B and 5T 2.0 
The stock housing is very cramped and holds in heat, Vertigo Performance Clutch Carrier has a large opening on the right side and an opening at the bottom to let fresh air in and clutch dust out. As well there is much greater clearance around the clutch bell for air movement..
