Will these work with my existing wheels and brake hardware?

These are M12 x 1.5 threaded — confirm your vehicle uses that size before ordering. If you're running aftermarket wheels, verify the lug hole depth accommodates extended-length nuts; shallow holes may cause fitment issues.

Do I need to prep or seal these before installation?

Aluminum oxidizes naturally over time, especially in wet climates. No prep is needed before install, but an occasional wipe-down keeps the orange finish bright. No sealant required — torque to your vehicle's specification and you're done.

Can I return or exchange if they don't fit my setup?

Check fitment carefully before ordering — verify thread pitch and extended length against your wheel offset and brake clearance. Contact ModSupply customer service with photos if fitment questions arise before purchase.
