These Grade 8.8 double ended studs are perfect for replacing your broken exhaust manifold studs. The stock units are not built for holding your heavy turbocharger on the side of your cylinder head. Remove your OEM studs using the "double nut" trick and drive these in until the broached point is bottomed out.

Each set Includes:

• 9X (complete set) of the Grade 8.8 Exhaust Manifold Studs

ARP Torque Specs

• Thread: M10 x 1.5, Grade 8.8 double-ended studs
• Torque: tighten to the turbo/manifold manufacturer's specification for M10 hardware — use anti-seize on the threads going into the head

All torque values assume ARP Ultra-Torque fastener assembly lubricant (included in the kit). Do not substitute motor oil — ARP notes it produces higher friction and inconsistent clamp load.

FAQ

Why replace the stock manifold studs?
Stock studs are not built to support the weight of a turbocharger hanging off the manifold. These Grade 8.8 studs are far stronger and resist snapping during heat cycles.
