What is the main benefit of a dual rate spring setup?

A dual rate spring setup uses two different springs that engage at different times. This allows for a softer initial ride over small bumps from the tender spring, while the stiffer main spring provides support during hard cornering or larger impacts, leading to reduced body roll and nose dive.

Does this kit include everything needed for the dual rate conversion?

Yes, the kit includes the dual rate springs, crossover rings for adjustment, and all necessary couplers to convert your UTV to a dual rate setup.

How do I know if this spring rate is right for my RZR?

This kit is specified as a 'Race - 250/300' setup, indicating it's tuned for more aggressive riding and performance. For optimal results, it's recommended to consult with FOX or a suspension specialist to ensure this spring rate aligns with your riding style and vehicle load.

Product Details

If you're looking to get more out of your Polaris RZR XP 1000's suspension, this dual rate spring upgrade kit from FOX is a solid option. It's designed to fit a range of RZR XP 1000 models from 2014 through 2019, including popular variants like the High Lifter Edition and the standard EPS models. This kit directly addresses common UTV handling issues by significantly cutting down on body roll during cornering and reducing nose dive when you hit the brakes or go over rough terrain.

What makes this kit stand out is the dual rate spring setup, which uses a softer tender spring for small bumps and a stiffer main spring that engages for larger impacts and during aggressive riding. This system includes crossover rings, allowing you to fine-tune how and when the main spring takes over. FOX uses high-grade springs in this kit, which are built to maintain their performance and resist sagging over time, ensuring consistent handling on the trail or track. The kit comes with everything needed to convert your existing setup to a true dual rate system, including the coupler rings.

This upgrade is a cost-effective way to achieve a more responsive and stable ride. The springs are finished in a silver powder coat, and the kit includes the necessary couplers to complete the installation.
