The Kyosho OT233B flange shaft is a 3x54mm replacement component for OPTIMA models, supplied as a matched pair. Its dimensional accuracy is intended to preserve smooth operation under normal running conditions.
These 3x54mm shafts are well suited to refreshing an OPTIMA during maintenance or rebuilds. Good tolerances help reduce unwanted movement in the driveline and improve consistency between runs.
Once you fit the Kyosho OT233B Flange Shaft, spin the assembly by hand and listen for any rough spots; if you feel resistance recheck seating and supporting parts. Keeping components clean before assembly will reduce premature wear.
