The Kyosho OT240B rear shock shaft is made specifically for the OPTIMA line, designed to replace tired parts and bring back smooth damper travel. Its accurate build is handy for tuners who want dependable suspension behaviour.
These shafts match the Kyosho OPTIMA shock geometry for a direct installation, letting you swap them in quickly during a service. They are suitable whether you are restoring stock performance or prepping a race setup.
With careful machining, the OT240B minimises binding and helps maintain steady shock movement, which supports predictable handling across different surfaces. That makes them useful for both track days and casual runs.
