Willspeed Associated B7 73mm Arm Pivot Strengthened Full Brace D Block

The Willspeed B7 73mm Arm Pivot Strengthened Full Brace D Block (W3086) delivers a wider rear pivot for 73mm wishbones, increasing pivot width by +5mm per side (10mm total). For the B7 platform, this D block secures to the underside of the gearbox rather than the chassis plate. Precision-machined from T6082 aluminium with increased wall and cross-sectional areas, it integrates the D block and roll bar mount into a single billet piece for rigidity and durability.
