Avid introduce this standard aluminium topshaft for Team Associated B4.2, T4.2, SC10.2, SC10B and C4.2 vehicles. The drop-in replacement is made from 7075 aluminium, comes hard anodised and saves about 6.7g of weight compared to the kit part for more acceleration and increased punch due to a lower rotation mass.
