Frequently Asked Questions
Do These Mud Flaps Affect Fuel Economy?
They minimally affect fuel economy; the mud flaps cause negligible aerodynamic impact, so any change to fuel efficiency is marginal. Most drivers will not notice measurable differences, especially at typical city and highway speeds.
Are Replacement Screws or Hardware Available Separately?
Are replacement screws or hardware available separately? The manufacturer notes replacement parts availability varies; customers may source screw compatibility options from CAT Automotive support or aftermarket suppliers to match screw size, thread, and corrosion resistance specifications.
Can They Be Painted or Customized Without Voiding Warranty?
They can be custom painted, but the company advises checking warranty implications first; unauthorized modifications or paint altering factory finish may affect coverage, so users should confirm custom paint options and warranty implications with seller or manufacturer.
Do They Make Noise or Flap at High Speeds?
They generally remain stable and exhibit low noise levels; flap stability is reinforced by heavy-duty rubber and screw-in mounting, though some users report minor flutter at very high speeds that typically diminishes after tightening or repositioning.
Are They Suitable for Winter De-Icing Salt Exposure?
Yes; satire aside, they brave winter like armored squirrels: springy rubber wards off grit. Winter corrosion resistance appears strong and salt exposure durability is adequate, though periodic cleaning and inspection are recommended to prolong service life.
