This is the Pro Armor Pre-Runner Bumper for the Polaris RZR. The package includes the bumper, mounting instructions, Pro Armor Sticker and all nuts and bolts required for installation. The hardware is fairly basic, just four lock nuts and four bolts. The shorter bolts install up top, the shorter bolts on the bottom. 
You can use a thread tap to thread the mounting holes with an 8mm tap but do it slowly as the holes in the chassis are located next to the radiator.
Once the holes are tapped, thread the upper bolts in on both sides and loosely tighten.
Next, thread the lower bolts on underneath the chassis through the lower skid plate section of the bumper.
Then tighten all four bolts using a socket wrench. It’s that simple!
