Shepherd V8 & V8.2 Front Oneway Drag-Assist Tuning Part - Arrowmax AM-930004  [AM-930004]

Front one-way upgrade for Shepherd V8 front differentials

This Arrowmax AM-930004 Drag Assisted Oneway is a replacement internal for Shepherd V8 and V8.2 front differentials intended to add drag-assisted one-way behaviour to influence front-end response during acceleration and corner transitions on road circuits.

The unit is a tuning component: it alters how torque is passed through the front differential so builders can fine-tune turn-in feel and mid-corner balance without modifying the main drivetrain geometry. The focus here is fitment, function, and setup considerations rather than a step-by-step install guide.

Installation notes: confirm diff housing clearance before assembly, use the recommended lubricants for diff oils and bearings, and recheck pinion and spur alignment after fitting. Perform controlled track tests to dial in the right mix of one-way action and diff oil viscosity for your setup.

For racers using Shepherd V8 or V8.2 front diffs who want a compact tuning lever for front traction and turn-in, this drag-assisted one-way gives a focused option to adjust how the front axle transfers torque without major drivetrain changes.
