Frequently Asked Questions
Will these work with my deep-dish wheels?
L40 extended length is designed for deeper offsets and wider wheels. Measure your current lug nut stack height or test-fit one before committing the full set to confirm clearance with your brake hardware.
Do the lock nuts come pre-installed on the lug nuts?
They ship as separate pieces — 20 lug nuts and 20 lock nuts. You'll thread them onto your wheel studs in order (lug nut first, then lock nut on top).
Can I reuse these if I swap wheels later?
Yes. Aluminum and steel don't seize easily, so you can remove and reinstall them multiple times. Hand-snug them first, then torque to your vehicle's spec — do not over-tighten aluminum.

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
