Description
If you’re running a Walker Evans-equipped RZR XP1K or WER XP Turbo Four Seater, suspension geometry matters—and this dual-rate spring setup delivers measurable improvements in handling and comfort. The SDI Shock Spring eliminates the compromises of single-spring systems by engaging both springs through the suspension stroke, giving you genuine control over body roll, front-end dive, and bottoming resistance. Whether you’re pushing hard on technical terrain or soaking up bigger hits, this fine-tuned package transforms your RZR’s ride quality and predictability.
