Polaris RZR-170 Complete Full Restraint system. Factory UTV offers a complete 4 point driver and passenger restraint system. Our system includes a bolt on cross bar to greatly improve belt attachment locations, 2 complete sets of Crow 4 point Restraints including sewn in padded shoulder straps and sternum cross straps and a block off kit for the holes left when the OEM seat belts are removed. Full restraints are the first mod we recommend to any new UTV owner. The stock belts simply don t hold a rider in place like restraints do. This is a safety improvement you cannot afford to pass up!
