Specs At A Glance

Good To Know

Q: How do I know this idler wheel fits my sled? A: Check that your machine matches the listed Mountain Cat 570 model years and that your current idler measures 5.630 inches across. Serial number and suspension configuration can affect fit, so verify before ordering.

Q: Is the bearing already installed in the wheel? A: Yes, the bearing comes pressed into the wheel so it can be bolted straight onto the suspension rail. Inspect your mounting hardware and spacers during installation and reuse or replace them as needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
