Taida T300 Camshaft for the Polaris RZR 170 is designed for performance racing heads. The T300 camshaft is one of the best upgrades for anyone who plans on making more power and better performance. The lobes improve the low and mid-range rpm, this increases the takeoff and the climb up to top speed. This cam is perfect for the Polaris RZR 170, it has that low-end power to help rip through the dirt and the mid-range power to keep it ripping. This paired up with a full top-end rebuild is one of the best combinations to get the power and speed you need.
