Polaris RZR XP 1000 - Valve Spring & Retainer Kits
Designed for high rpm, BC valve springs by PAC Racing are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. Choose from the premium beehive design valve spring or the dual for those who perfer added pressure. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances. The titanium retainer option is only designed to work in race only applications with limited miles (under 2500 annually). BC H13 tool steel retainers are the correct choice for those looking to install the kit and forget about it for the rest of the engine's cycle life. Tool steel offers the ultimate in wear resistance. For those looking for an economical alternative, BC's 4140 chromoly steel retainers are the correct choice, but the wear characteristics are not as durable as the tool steel option.

Polaris RZR XP 1000 Stainless Steel Valves
BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel material to insure reliability with high boost and/or high rpm applications. The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber. Every valve is fully machined and features a swirl polished finish under the head. BC premium exhaust valves are made from Nimonic 90 blend with 5 times more tensile strength than stainless steel and a max temperature rating of 2400°F…these are the choice when running high boost.
