Tuner Lug Bolt 14x1.50 Thread 40MM Shank
Fitment and specs
- Thread size: 14x1.50
- Shank length: 40mm
- Seat type: tuner seat
- Lug bolt that fastens the wheel directly to the hub
A longer 40mm shank gives deeper thread engagement, so it pairs well with thicker wheels or spacers that call for extra reach. Seat each bolt by hand, torque to your vehicle's factory specification per the torque reference chart, then re-torque after the first 50 to 100 miles.
Common questions
Why choose a 40mm shank?
Longer shanks maintain full thread engagement when the wheel or an added spacer increases the distance to the hub. Match the length to your setup.
Are tuner and conical seats interchangeable?
No. A tuner seat is not the same as a conical or ball seat. Use bolts that match the seat cut into your wheels.
