Arrowmax AM-930004 Drag Assisted Oneway for Shepherd V8 & V8.2 Front Differential  [AM-930004]

Front Oneway for Shepherd V8 Series

This Arrowmax AM-930004 Drag Assisted Oneway is an RC-scale replacement part designed to work with Shepherd V8 and V8.2 front differentials. It provides a drag-assisted one-way action intended to influence front-end behaviour under acceleration and corner transition in on-road and track setups.

The unit's role in a front differential is tuning-oriented: it changes how torque is transferred during differential action so builders can fine-tune turn-in and mid-corner balance without altering major drivetrain components. This description focuses on fitment, function, and tuning considerations rather than step-by-step installation.

Installation notes: verify differential housing clearance, use the manufacturer's recommended lubricant for diff oils and bearings, and check that pinions and spur alignment remain within spec after fitting. Testing under controlled track conditions will help determine the preferred combination of one-way action and diff oil to achieve the desired handling.

For builders running Shepherd V8 or V8.2 front diffs who want a focused tuning lever for front-end behaviour, this Drag Assisted Oneway provides a compact option to adjust traction transfer and turn-in response without changing major drivetrain geometry.
