Revolution Design Racing Products have introduced aluminium battery thumb nuts for The XRAY XB2 series. The parts offer a cool new design with a larger outer diameter and deep grooves compared to the standard parts, making for exceptional grip and easier battery swaps. Machined from aircraft-grade 7075-T6 aluminium and coming orange or black anodised the nuts sport machined silver edge details and laser-etched RDRP logos for cool looks. The nuts come in pairs of two and also fit the 4WD line of XRAY vehicles.
