This is a fluorescent yellow version of the Mini 4WD front under guard, which serves as a brake and helps your car stay on track after jump landings. Made from a low-friction resin material, it also helps your Mini 4WD racer keep its momentum through tricky grass sections. Its 3-piece configuration enables both normal and wide roller settings. Two sets of under guards with different thicknesses are included for use with large and small diameter wheels.
