If you need a replacement short slide spring for your Arctic Cat snowmobile, this OEM part (2604-515) is exactly what you're looking for. It replaces the older part number 0604-403 and fits a huge range of Arctic Cat models across multiple years. We're talking Sabercat 500, 600, 700 models from the mid-2000s, various Sno-Pro models from 2003-2014, Thundercat 900 and 1000 series, Wildcat models from the 90s, XF series from 2014-2019, and Z series from 1999-2003. That's pretty much covering decades of Arctic Cat snowmobiles! Having the correct spring is crucial for proper suspension performance and ride quality - too stiff and you'll feel every bump, too soft and you'll bottom out. This genuine OEM part ensures perfect fit and performance compatibility with your specific model. Whether you're doing maintenance, repairs, or upgrades, using the right spring makes all the difference in how your sled handles on the trail or in powder. The quality matches what came on your sled originally, so you know it's built to Arctic Cat's standards. If your current springs are worn out, sagging, or broken, this replacement will restore your suspension to proper working order. It's one of those maintenance items that snowmobile owners eventually need, and having the correct OEM part ensures everything works together as designed for optimal performance and safety on the snow.
