Restore Your Ride Quality When the tender springs start to sag on your RZR, your ride quality goes to crap. You lose ride height and every bump feels like you™re getting whacked by a sledgehammer. Replace them with SuperATV™s Polaris RZR PRO XP Tender Springs. They refresh your suspension so you can get back to the plush ride you remember. American-Made Strength This kit of 4 heavy-duty springs is made from ultra-durable spring steel and made right here in America. They make heavy hits feel softer and give you a smoother ride without bucking like crazy.
