Why the 4-Seat Pro S Wide-Body Needs Its Own Dual Rate Kit

The RZR Pro S 4 Seater combines the widest stance in the RZR lineup with the highest passenger capacity — which creates unique spring rate requirements. The wide-body chassis distributes weight differently than a standard-width RZR, and 4 passengers add significant load that a 2-seat spring kit isn't tuned for. A spring that's correctly rated for 2 passengers will feel too soft under full load in a 4-seater, leading to excessive body roll and bottoming. The AllThingz UTV dual rate kit is specifically tuned for the 4-seat Pro S chassis weight and load distribution, ensuring the progressive spring rate curve works correctly whether you're riding solo or with a full crew.
