Shimano Hub Parts Set For. Nexus 8 CJ-NX40 - Black

Get your Shimano 8-speed hub shifting perfectly with the NEXUS/ALFINE SM-8S31 small-parts kit (for standard/horizontal dropouts, CJ-8S40). This genuine hardware set is tailored for Nexus and Alfine 8-speed internal-gear hubs and includes everything needed to restore factory-smooth operation and secure cable actuation on frames with standard dropouts: a CJ-8S40 cassette joint, 7R/7L non-turn washers (black/grey) for correct axle orientation, two 3/8" cap nuts, a driver cap, and a cassette joint fixing ring (supplied without retail box). The non-turn washers index the axle to prevent rotation under load, the cassette joint translates shifter input into precise gear changes, and the included nuts and caps complete a clean, durable installation—ideal for new builds, hub swaps, or servicing city, trekking, and e-bikes running Shimano 8-speed IGH systems.
