Frequently Asked Questions
Will these fit my existing wheels without modification?
M12x1.25 lugs are a common fitment across many vehicles, but verify your current lug thread size and seat type before ordering. If your wheels accept M12x1.25 open-end lugs, these mount directly without modification.
Do I need to torque these differently than stock lugs?
Tighten to your vehicle manufacturer's specified torque value listed in the service manual. Aluminum lugs should not be over-tightened, as they're more prone to thread stripping than steel—follow factory specs exactly.
Can I mix these with my existing lugs, or do I need all 20?
Most wheels use 4 or 5 lugs per wheel. You'll need one lug per hole, so 4 or 5 per wheel depending on your bolt pattern. The 20-piece set covers four to five wheels; mixing aluminum and steel on the same wheel is not recommended for balanced clamping force.
