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.
