Valve Cover Studs

Quadstar Tuning LLC

  • $32.00


Set of 16 Studs and matching nuts to replace factory valve cover stud/nut combos. Eliminate gasket alignment issues and facilitate quick/easy valve cover installation on your 6.2 or 6.5L diesel engine.  If you've ever fought with leaks and mis-alignment before, you know why these are a must-have item.

Another problem these avoid is hydro locking the bolt holes with sealant during assembly which can crack heads and intake ports!  Installing studs will ensure the job goes smoothly.
