HCR Racing Polaris RZR XP1000/Turbo Duner Long Travel Suspension Kit
Following the design of HCR's proven Dual-Sport Kit, the re-designed Duner series has been created for the serious dune enthusiasts who wants the addition strength without the weight. This new proprietary design lightens the product without compromise. The alloy used to manufacture the Duner kit is 30% stronger in tensile and yield strength compared to 4130 Series chromoly. The material endures several processes and is hardened for better wear resistance and overall strength. Every external weld is an internal plate structured into the design. While the cost-effective approach is to run tube ends for ball joints , all HCR kits run a 4130 heat treated billet end allowing all internal and external plating to be attached to this billet eliminating a potential weak point. Billets are available in both ball joint and Uniball applications
