Kolpin offers the most extensive line-up of overfenders available! Added protection from flying mud or debris, or to enhance the look of your ATV. Average extended width is 3. Constructed of vacuum-formed HMW haircell polyethylene so they are rigid, yet flexible to withstand all kinds of potential abuse. Each model is custom designed to look like they came direct from the factory. Installation requires drilling- hardware included. A must for use with larger wheels and widening kits. Sold in a set of four pieces.
