Thank you for purchasing MudBusters for your 2010-2014 Polaris Ranger Midsize! Our mud guards/extended fenders were designed to deflect debris and reduce the amount of mud that typically gets thrown from the tires into unwanted areas. These fenders are made from high-quality materials. They can withstand a lot of abuse, but they are not designed for crash protection, absorbing impacts, rollovers, or for uprooting trees. If you have an accident or if you happen to damage your fenders, replacement fenders can be ordered on our website and by phone at a discount for existing customers. Unlike other manufacturers, you do not have to buy a complete set if you damage just one.


Some of the pictures in the instructions below may differ from the actual product. In a constant effort to increase customer satisfaction, we may change the style, material, and/or the hardware to better serve you. If your fenders get slightly distorted while in transit, apply pressure to the distorted areas to straighten them out before installation. If you wish to remove your fenders, you can plug any drilled hole with a standard 8mm plastic rivet for a factory look.
Use caution when drilling into the factory panels of your vehicle. Make that you do not penetrate surrounding parts or the chassis (unless instructed). Self-tapping screws and push rivets are an effective way to fasten the fender flares to your machine and are provided for an easy installation. However, you can use other methods of securing our extended fenders to your vehicle as well (i.e. rivets, misc hardware, etc). Remember, it may be helpful to have a friend assist you with the installation.


MudBusters are formed to fit your machine but are shipped in a narrow box. You may find it necessary to apply pressure and re-bend some of your fenders for a better fit. Don’t worry, they’re very durable!
