EMPI 10mm Chromoly Case Stud Kit — Stock Length | VW Type 1 Air-Cooled (00-4009-0)

EMPI 10mm Chromoly Case Stud Kit — Stock Length, Dual-Port (00-4009-0)

Stock 8mm case studs stretch and pull out under the clamping load of a built motor — it's one of the classic air-cooled failures. This is EMPI's 10mm chromoly case stud kit (00-4009-0) in stock length, the upgrade that gives a performance or stroker engine the even, high clamping force it needs to hold a head gasket seal. For dual-port heads.

Frequently Asked Questions
