Do I need to remove the bumper cover to install this?

Yes. The reinforcement bar mounts underneath, so you'll need to take off the rear bumper cover first. Once installed, the cover bolts back on normally.

Will this work with an aftermarket bumper or body kit?

This reinforcement is designed for factory Maxima bumpers. If you're running an aftermarket bumper, verify that the mounting points align with this bar before purchase.

Does this come with bolts and hardware?

Reinforcement bar only—no fasteners included. You'll use the factory bolt holes, so gather any hardware needed before installation to avoid delays.
