T-Works have introduced new aluminium centre driveshafts for the Team Associated B64 and B64D. Machined from high-quality 7075-T6 aluminium, they come black anodised, laser-etched for easy identification and feature durable steel pins. They weigh half the weight than the stock driveshafts. The centre driveshafts are available in 82mm and 110mm for FW and 95mm and 102mm for BW separately or as combo set.
