175RC B6/B6D Titanium Piston/Bleeder Screws are trick, strong and lightweight. Compatible with B6 shocks with V2 shafts, these screws decrease weight in areas where titanium has never been used before. These M2 screws are used in the shock cap bleeder screw, and to hold the piston to the shock shaft. They can also be used as hinge pin retainers on AE suspension arms that use a M2x4 screw. Package includes eight 2x4mm titanium screws, enough to replace the shock piston screws and shock cap bleeder screws on 4 shocks, and a reusable parts tube.
