T-Track genoa lead cars are used where frequent lead adjustments are not required. T-Track cars have an integral pinstop to lock the car into position. The car’s one-piece, solid aluminum construction is lightweight and strong. The stainless steel carrier tilts side-to-side to ensure a fair lead. For sailors who do not want to switch their existing T-Track to ball bearing track, the GT326S pinstop car fits all 32 mm and 1-1/4" T-Track. Plastic inserts in three sizes ensure a correct fit.
