King Performance Titanium Engine Install Bolt Kit | VW Beetle Engine-to-Transaxle | 10mm x 1.5 Bolts & 12-Point Flange Nuts, 6-Piece Grade 5

King Performance Titanium Engine Install Bolt Kit — VW Beetle, 6-Piece Grade 5

Four fasteners hold an air-cooled VW engine to the transaxle, and they come out every time the engine does. Stock steel hardware rusts, the nuts round off, and after a few pulls the threads are tired. The King Performance Titanium Engine Install Bolts Kit replaces that hardware with Grade 5 titanium (Ti-6Al-4V): two long 10mm x 1.5 bolts and four 12-point locking flange nuts — including the nut for the lower starter location. It is a small kit that you will touch at every engine swap, so it is worth doing right.

Vehicle Fitment

• VW Beetle (King lists it for "VW bugs") — air-cooled Type 1 engine to Type 1 transaxle.
• Commonly shared by other Beetle-pan cars such as the Karmann Ghia, Baja Bugs and VW-based dune buggies. Bolt lengths vary with starter and bellhousing combinations, so compare the 110mm and 70mm lengths with the hardware you are removing.

What's in the Kit

• 1 × bolt, 10mm x 1.5 x 110mm
• 1 × bolt, 10mm x 1.5 x 70mm
• 4 × 12-point locking flange nuts, 19mm flange / 14mm head (the fourth nut is for the lower starter location)

Key Features & Benefits

• Grade 5 titanium: strong, much lighter than steel and rust-proof — ideal for hardware that comes out at every engine pull.
• Hot-forged, rolled threads for fatigue resistance.
• Locking 12-point flange nuts: a compact 14mm head with a wide 19mm flange for clamping against the bellhousing.
• Matches King's other titanium chassis and engine hardware.

Technical Specifications

Installation Notes

• Use anti-seize on all titanium threads — King's instruction for every titanium fastener.
• Seat the engine fully on the transaxle before snugging any nut; never use the fasteners to pull the engine into place.
• Tighten evenly by hand and torque to the factory engine-to-transaxle specification. No impact tools on titanium.

Frequently Asked Questions

• Why four nuts but only two bolts? The other nuts go on the existing engine-mount studs; King notes the fourth nut is for the lower starter location.
• Will it fit my dune buggy? Most Beetle-pan buggies use the Beetle engine and transaxle, but compare the bolt lengths with your hardware first.
• Do I need anti-seize? Yes, on all titanium threads.
• Is it street legal? King sells it for off-highway use only.
