Does this diffuser require the DL-R bumper to install?

Yes. This diffuser is engineered specifically for the DL-R rear bumper platform and must be used together. The two components are designed to align and mount as a system, so verify you have the matching bumper before ordering.

Will this scrape on driveways or steep inclines?

Diffusers mount low at the rear. Approach angles and driveway clearance depend on your vehicle's suspension setup and ride height. Measure your ground clearance before installation and test gently on your first few drives to confirm safe spacing.

What prep work do I need to do before painting?

Sand the surface with appropriate grit to promote paint adhesion, then clean thoroughly to remove all dust and debris. Follow your paint manufacturer's instructions for application. Proper surface prep is essential for finish durability and appearance.
