The RDRP B74 Aluminium Rear Hub Set was developed as a direct fit upgrade for the B74. The rear hubs feature an updated design that provides improved durability for heavy duty competition use, while offering grub screw retainers for the standard kit suspension geometry inserts (ASC92178), greatly reducing slop over the conventional design. The hubs use the standard kit rear hub link mounts, making them a direct fit and they come machined from aircraft-grade 7075-T6 aluminium. A black surface coating and machined silver chamferred edge details make the parts stand out.
