Brian Crower 2016+ Polaris XP1000, XP Turbo, XP Turbo-S - 4 SEAT Roller Cage Fastener Kit

The Brian Crower BC9000-4 is a roll cage bolt kit designed for 4-seat Polaris RZR models. It replaces factory fasteners with aerospace-grade bolts from ARP (Automotive Racing Products) to enhance chassis rigidity, occupant safety, and long-term reliability.

These ARP bolts are forged from 8740 chromoly steel and undergo ARP’s proprietary heat treatment and cryogenic stabilization process for superior strength and durability. They feature rolled threads, which are stronger and less prone to stripping than cut threads. The bolts are coated with a proprietary anti-friction lubricant for consistent clamp load and to prevent thread galling.
