VSC Performance 14mm Head Stud Kit EJ Motor

VSC Performance is the parts branch of Vermont SportsCar, the legendary builder of Subaru rally cars and the company responsible for all of Subaru of America's motorsports programs. 

These motorsports-derived head studs are exactly what are used in some of Vermont SportsCar's most wicked builds, up to and including Travis Pastrana's 862-hp Airslayer STI. They are able to withstand higher compression and higher boost levels without the risk of head lift.

The studs are custom-manufactured by ARP to VSC Performance specifications. The special M14x2.0 thread pitch was arrived at after decades of real-world motorsports testing. The hardened steel studs feature Allen key compatibility for easy assembly.

Kit includes twelve head studs, matching 12-point fasteners, washers, and assembly lube. Note that you MUST have a machine shop machine your block to accept these studs!

Fits all 2002-2014 Subaru WRX and 2004-2021 WRX STI, plus most other EJ motor Subaru cars.
