STUD MANIFOLD MEDIUM 3/8
1¾ inch (≈44 mm)
Manifold stud 3/8" - medium length
For mounting exhaust and inlet manifolds to engine block

Features
- Double thread: 3/8"-16 coarse on engine block side, 3/8"-24 fine on nut side
- Medium length version for different manifold thicknesses
- Heat-resistant material for exhaust system
- Replacement part for worn or broken studs
- Fit with thread sealant on the portion entering the engine block (seals coolant passages)
★ Essential component for a solid and leak-free manifold mounting. High temperatures and thermal cycling can crack original studs — timely replacement prevents exhaust leaks.
Application
For jeeps fitted with L-134 (Go Devil) or F-134 engines. Each manifold requires multiple studs in different lengths (short, medium, long) depending on position, as manifolds vary in thickness at different mounting points.
Installation notes
Apply thread sealant to the portion being screwed into the engine block — this seals the coolant passages at the ends of the block. Screw the stud firmly into the block, fit the manifold and secure with copper or brass nut and lock washer. Check torque after the first heat cycle, as gaskets may settle.
Compatibility
Three stud lengths are available (short, medium, long) as the manifold has different thicknesses at different locations. Check which length is required for each mounting position. Not all positions use the same length.
Historical context
During WWII, some Willys MB jeeps used studs for manifold mounting, whilst Ford GPW variants sometimes used bolts — both systems were permitted under military specifications.
