Mounting  Depending on the design of your current tray or trailer, you may need to space the mudguards down from the undertray surface to sit inline with your tray side profile, this can be done with uni-strut, box section, spacers or washers for small distances, Rivet nuts aka ‘Nutserts’ are a great way to fix box section profiles allowing a thread for bolting to, iBuilt Kits does not recommend the use of ‘Tek Screws’ for attachment to your tray. For additional strength, ‘Sikaflex’ or similar adhesive can be used along with fastening bolts.

Preparation – If you wish to have your parts painted or powder-coated, parts should be given a light sanding with 180-240 grit paper for best results.
