5526 12 × 18 in RoadSport TNT flat splash guard Black rubber; plain face
Universal refers to adaptable mounting, not guaranteed fit. The listed measurements describe the splashguards, not your fender opening. Check tire movement, ground clearance, wheel-arch contours and hardware requirements before installing. A no-drill description should not be assumed for every vehicle.

How to select the right mud flaps

  • Choose coverage first: measure the desired horizontal width behind the tire and the allowable vertical drop above road obstructions.
  • Check the wheel arch: note where a flat flap can sit securely, without interference from flares, steps, tailpipes or trailer connections.
  • Compare construction: all listed products are black rubber pairs; some styles have logo or reflector details, while others are plain.
  • Retain adequate clearance: consider full suspension movement, steering lock at the front wheels and vehicle load conditions.
  • Install as instructed: confirm mounting screws or brackets for the actual vehicle; holes might not align with the original mud flaps.
