Optitorque Technologies are a USA based specialist fastener manufacturer. Our Barra head Torque Master studs are rated at an amazing 240,000-260,000psi ultimate tensile strength. Our studs will handle more boost than our competitor’s offerings (excluding ARP Custom Age 625+). Our studs offer an economical stud upgrade to ARP2000 without the high expense of CA625+. Our Nissan RB 1/2″ version has been tested to 90psi boost successfully. Don’t be fooled by cheap studs, just because they have a nut on top does not guarantee better performance. Kits include 12 point nuts and large diameter washers.
