SandCraft 2014-2021 Polaris RZR S 900 / S 1000 / RS1 Race Collar Assembly (101 Spline Shaft)
The SandCraft Driveline Race Collar Assembly for the 2014-2021 Polaris RZR S 900, S 1000, and RS1 (101 Spline Shaft) is a patent-pending upgrade engineered specifically to handle the most extreme off-road riding conditions. The factory Polaris driveline utilizes a slip yoke at the rear transmission output shaft. Because the motor is rubber-mounted, aggressive driving causes engine movement that severely loads the driveline. Under these intense conditions, the stock pressed-fit bearing on the carrier bearing shaft can actually pull completely out, instantly disabling your 4-wheel drive capabilities.
SandCraft solves this critical weak point with their innovative Race Collar Assembly. Designed to securely lock the driveline components in place, this 101 spline shaft collar prevents the slip yoke and bearing from separating under heavy load or chassis flex. If you ride hard in the dunes, mud, or desert, this simple but highly effective upgrade is essential to keep your 4WD fully engaged and prevent catastrophic driveline failure out on the trail.
