Front Shock Tower for BD9 (Graphite, +1mm Pivot) - Yokomo B9-017U1A  [B9-017U1A]

BD9 Front Shock Mount Details

This graphite front shock tower is intended for BD9-series touring cars and changes the suspension geometry by raising the shock pivot 1mm. Increasing the pivot height expands the shock's upper stroke, helping to prevent the damper from bottoming under substantial roll or sudden wheel drop scenarios.

The upgrade targets handling refinement: the altered leverage adds measured compliance at full compression and promotes a steadier chassis through quick direction changes. Fit this tower to reduce hard bottom-outs without needing to alter spring stiffness or core damper settings.

Fitting is straightforward for those comfortable servicing BD9 chassis components. Remove the factory tower with your hex tool and install the replacement using the original fasteners; once fitted, inspect shock shaft freeplay and fine-tune ride height and droop to suit your set-up.
