Inferno-compatible Front Universal Swing Shaft Kyosho IF125B  [KY-IF125B]

Front driveline replacement for Inferno NEO chassis

The Kyosho IF125B Universal Swing Shaft (Front) is an RC-scale replacement designed for use on Inferno MP Series layouts that correspond to the NEO 3.0 & 4.0 models. It provides a direct swap option where the chassis and parts arrangement match, helping reinstate front-wheel driveline function after impact or wear.

Compatibility and role: this front universal swing shaft is specified for Inferno MP Series NEO 3.0 & 4.0 chassis. Fit the part when a bent or worn front shaft is reducing steering precision or front traction, noting it is a component-level replacement rather than a whole assembly improvement.

Installation and tuning notes: intended to replace the original front swing shaft without significant chassis modification, the part requires checks for spline alignment and hub/gearbox clearance before final assembly. Ensure pins, hexes, and bearings are in good order because minor bearing or alignment faults commonly present as wheel play or binding during suspension travel.

Practical advice: retain original mounting hardware where serviceable and inspect adjacent walk shafts and universal joints for wear when replacing the shaft. Pairing replacement of worn mating components with the new shaft gives the best outcome when repairing a damaged front driveline.
