Recommended Torque Specs
Below are our general recommendations for torque specs. Please note:
- For torque specs involving other parts, always verify the maximum torque specs from the respective PARTS manufacturer.
- Never exceed the lowest of the manufacturer-recommended and the OPEN-recommended maximum torque spec
- All bolts should be greased prior to assembly.
- Always use a torque wrench!!
