Frequently Asked Questions
Will these fit my aftermarket wheels with spacers?
The 45mm extended length is designed to work with thicker wheel setups and spacers. Verify your wheel hub and brake clearance before install β some aggressive offsets may need measurement.
Do I need a special tool to remove the locking nuts?
Yes. Four of these nuts are locks that require the included unique key for removal. Keep the key stored safely; it's the only tool that opens them.
What torque spec should I use when installing?
Refer to your vehicle's service manual for the correct torque value for M12 x 1.25 lug nuts β specs vary by manufacturer. Hand-snug first, then use a calibrated wrench or torque stick for final tightening.
