GPS's titanium drive flange stud kits, a reliable alternative to mounting rear drive flanges to rear hubs without the use of bolts. Available for both 5-bolt and 8-bolt hubs/drive flanges, kits are sold complete with either (10) or (16) titanium studs, washers, and nuts. By using this kit, you can reduce unsprung and rotating mass while also preventing corrosion. Each kit is sold by the axle set and includes enough hardware to mount (2) hubs. You can choose from either 5-bolt or 8-bolt options from the drop-down menu. If using Strange Oval articulating drive flanges, choose the appropriate option in the menu to ensure the correct part.
