Shepherd V8 Front Diff Tuning Oneway - Arrowmax AM-930004  [AM-930004]

Oneway tuning unit for Shepherd V8 front differentials

The Arrowmax AM-930004 Drag Assisted Oneway is a replacement one-way intended for use in Shepherd V8 and V8.2 front differentials. It provides drag-assisted action to influence front axle behaviour during acceleration and while changing direction on track.

As a tuning element, the one-way changes how torque is transferred across the front differential, letting builders refine turn-in and mid-corner balance without modifying primary drivetrain parts. This content emphasises compatibility, function, and setup considerations rather than step-by-step fitting instructions.

Fitting advice: make sure diff housing clearance is sufficient, follow recommendations for diff oil and bearing lubrication, and recheck gear alignment after fitting. Use careful track testing to pair the one-way characteristic with suitable diff oils for predictable handling.

For drivers using Shepherd V8 or V8.2 front diffs, this drag-assisted one-way is a compact tuning option to alter front traction transfer and initial turn-in without changing major drivetrain geometry.
