Thank you four purchasing MudBusters for the 2015-2020 Polaris RZR-4 900, RZR XC-900, RZR 900, RZR-S 900 and 2016-2020 RZR S 1000! Your new 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 textured HMW. 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 differe 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.
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!
Front Fender Flare Installation
- Place the fender flare against the inside of the factory front fender.
- On the lower portion of the fender flare, you will notice 3 machined slots. Place the slots over the clips in the factory fender and manipulate the fender flare until all of the clips are protruding through the machined slots in the fender flare Figure 2
- Once the lower portion of the front fender flare is clipped in, push the inside of the fender flare against the bends in the factory fender. Clamps can be used to assist with holding the fender flare into position.
- Insert self-tapping screws along the inside of the fender flare. Once the inside edge is secure, you can add more screws to theoutside of the fender to close in any gaps (be certain not to drill into any areas where the tips of the screws might be seen on the outside of the vehicle. Figure 2
Rear Fender Flare Installation
- Place the fender flare against the inside of the factory rear fender.
- Once the fender is in the desired position (as seen in Figure 3), use clamps tohold the fender flare in place.
- Mark the holes with a drill punch or a marker. (see Figure 3).
- With the fender flare clamped against the factory fender, drill (1) 1/4” hole andinsert (1) 1/4" x 3/4” bolt with a washer and a lock nut (on the back side).
- Repeat step 4 until all of the holes are drilled with hardware installed.
- Proceed to the rear fender flare mounting points (see Figure 4)
- Mark the holes with a drill punch or a marker.
