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.

Newsflash!!! Team TRP Nissan broke into the 5-sec zone in their Nissan 350z at the recent Grudge Kings @ Sydney Dragway in August 2022. Domenic Rigoli uses Optitorque head studs to harness the massive cylinder pressures in his RB powered ride. Racemax have a fast growing range of engine fasteners for several popular platforms such as Nissan RB, SR20, Barra and LS.
