Polaris RZR XP 1000 Camshafts
BC Brian Crower Polaris XP 1000 camshafts are brand new, semi-finished cam cores that allows the capability to grind unlimited lobe specifications while still maintaining the factory base circle size. Up until this point, the only camshaft options available for the Polaris XP 1000 were regrinds cut from stock cam cores, which greatly restricts the amount of lift and duration possible due to base circle limitations, or expensive hardfacing or hard welding of stock cam cores. While hardfacing does allow for unlimited spec, you're at the mercy of these "welded up lobes" holding up over time and if they don't, you've got debris in your engine. The Polaris RZR XP 1000, built by ProStar, was first introduced in the RZR chassis back in 2014 and is still a current engine platform today. The 999cc engine features dual overhead camshafts (DOHC), solid bucket type cam followers, 4 valves per cylinder, wet sump, dual 48mm throttle bodies and EFI with new long tip fuel injectors, ensuring each cylinder is supplied with the air and fuel it needs to produce unmatched power on demand. To achieve the 999cc displacement, the XP 1000 features a 93mm cylinder bore x 73.5mm stroke crankshaft in a 180 degree configuration with 11:1 compression ratio. To deliver that power to the wheels, the RZR XP 1000 has an ultra-efficient driveline featuring a retuned, high performance CVT system to distribute the 110 (stock) horsepower from the engine to the transmission with 71 ft lbs of torque. Polaris also specifically geared the transmission to optimize the power of the ProStar engine. With greater than 80 percent of peak engine torque available from 3500 to redline, the RZR XP 1000 has huge torque on tap for the most aggressive dune and desert riding.

Total Performance Racing (www.tprindustry.com) has revolutionized the cam chain tensioner for the Polaris RZR engine platform, delivering the ability to adjust chain tightness while the engine is running! The TPR tensioner allows for proper setting on cold starts and then again, with the turn of a knob, after the engine gets hot. This keeps the chain taught at the proper tension, virtually eliminating jumping teeth on the gears and causing catastrophic engine damage. Easy turn knob with easy to read laser indicators delivers precise tuning that also eliminates cam chain noise. CNC machined in-house at our state-of-the-art R&D facility, the tensioner body and tuning knob are made from 6061 billet aluminum, the shaft and foot internals from 17-4 stainless steel and features ARP fasteners for secure clamping. Easy installation, fits Polaris XP1000, XPTurbo, Turbo-S, ProXP and XP900.
