SDI Shock Spring - RZR XP1K Four Seater UDCSKP-1K4

Stock RZR suspension geometry wasn't designed to handle the demands of aggressive trail riding, jumping, or multi-passenger loads without excessive body roll and bottoming. The SDI Shock Spring kit transforms your XP1K Four Seater into a genuinely dual-rate suspended platform by pairing tender and main springs, delivering the compliance you need for small bumps while maintaining the support required for hard impacts. If you're running Walker Evans shocks and want to dial in your ride quality without a complete suspension overhaul, this is the most direct path to measurable improvements in handling, stability, and driver confidence.
