The 3Racing Aluminum Rear Differential Housing is a direct upgrade for Kyosho FW05-R and FW05RR owners seeking improved case strength. Its aluminium body is aimed at reducing wear under competitive use.
Aluminium brings a solid strength to mass ratio and helps dissipate heat from the differential area. That makes the part suited to repeated hard runs where plastic housings can soften or wear.
Designed to match the original mounting points on FW05-R and FW05RR cars, installation uses common RC tools and should be quick for anyone familiar with basic maintenance.
