Fitment: (2018) Polaris RZR XP Turbo S. NOTE: Will not work on other models. To take the already impressive RZR Turbo S one step further, HCR developed an American made product with is lighter, leaner and meaner to compliment the aggression of the new model. The RZR Turbo S, along with HCR's Complete line of suspension systems, is manufacturing using HCR Elite Material. This proprietary material boasts 30 percent stronger tensile and yield strength compared to 4130 Chromoly. The material goes through several processes and is hardened for better wear resistance and overall strength. An intensive process is used during each design to simulate and refine the geometry to match the characteristics of the stock suspension. Critical measurements are verified, such as ball joint angle, CV Joint angle, and clearance to surrounding parts to ensure no binding or interference. The quality fit and finish, ease of installation, and top shelf performance of these kits are what sets HCR Racing apart from the competition. Through intensive craftsmanship, meticulous precision and BOLD aesthetics, we strive to make HCR your #1 Choice. Kit Includes: 2 Rear Trailing Arms, brake line bolts, (2) lower rear shock bolts and rear sway bar bolts.
