Frequently Asked Questions
Will these fit my wheel without rubbing the suspension?
The 50mm extended length is built for wheels with spacers or deep offsets. Test-fit against your suspension before final tightening to confirm clearance, especially if running a tight setup.
Do I need to use the adapter socket that's included?
The adapter makes installation easier, but it's not required. You can use a standard 19mm or 21mm socket depending on your lug nut size—just verify the fit before committing to your impact gun.
Should I torque these the same as my factory lug nuts?
Refer to your vehicle's service manual for the correct torque specification—aluminum and steel lugs may have different requirements depending on your hub design. Always use a torque wrench for final tightening.
