These front cage mount pillars made a perfect addition to your aftermarket roll cage. They replace the weak factory parts which are well known for bending. This bending causes the rest of the cage to give out even easier during a roll-over. When these RZR Tech Cage Pillars are used with an aftermarket cage they make the set up virtually indestructible. The Pillars actually tie the frame together is this area much better as well. By spreading out the base substantially these mounts disperse the load applied to the chassis in the event of a roll over. There are three holes per side which will need to be drilled to install this product. Parts come powder coated and with all necessary hardware for installation. These Cage Pillars will fit any model or year and they duplicate the factory mounting location. They can be used with a factory cage or any aftermarket one. SOLD IN PAIRS.
