Optitorque Head Studs to suit BA BF FG Falcon Barra 4L 6 Cylinder DOHC.
This Head Stud kit drops straight into the Barra DOHC 4L 6 Cylinder engine. The kit includes:
- 14 x Torque Master 240,000psi high tensile M12 Head Studs
- 14 x Large Diameter Washers
- 14 x 12 Point Head Nuts
Optitorque Torque Master studs are made in the USA, rated at 240,000-260,000psi ultimate tensile strength and will handle more boost for less cost than competitor’s offerings.
These head studs are an economical upgrade to our ARP2000 set, but without the high cost of ARP CA625+. The Nissan RB 1/2″ version has been tested to 90psi boost successfully.
Don’t be fooled by cheap Chinese studs, just because they have a nut on top does not guarantee better performance.
