NAMI Electric stock factory shaft for the top of rear suspension.
Suits all Burn-e and Blast models.
Length: 50mm length.
Outer diameter: 12mm.
Weight: 33 grams.
The shaft is a pair screw (threaded) without the screws/bolts (for each end of shaft). In most instances you can re-use the stock socket head screw. The thread inside the shaft is M8 with 14mm depth of thread. The stock screws for the top rear are socket head A2 stainless (no need to be load bearing). If you need bolts, choose the option and a pair of Black 10.9 Button Head M8 16mm screws will be provided.
Typically required when original has deformed which would result in vertical "play" in the shaft and a "knocking sound". This sound and feel can be observed when front wheel is lifted off the ground. In these instances, accurate measurement tools such as micrometre or callipers will reveal the shaft diameter has worn to ~11.96mm, which is a <0.4mm reduction.
Consider including an optional bushing if using the factory stock KKE shocks. Often these need be renewed if "play" is observed. This is the self lubricating bearing that sits inside the shaft of the shock as explained on the KKE suspension product page. Press out the original (a suitably sized socket from a socket set with drift is usually suitable). Press in the renewed bearing in same manner. The bush has 12mm inner diameter, 14mm external diameter, 15mm length and in most instances can be tapped in and out with appropriate sized drift.
