Idler Wheel Rubber 5.13" for Ski-Doo Nordic 371 399 1969-1971

Idler Wheel Rubber 5.13" for Ski-Doo Nordic 371/399

This 5.13 inch idler wheel rubber is a replacement wear component for the rear suspension idler wheels on Ski-Doo Nordic 371 and 399 snowmobiles, restoring smooth track guidance and reducing friction along the slide rail.

Overview

This idler wheel rubber is made to refresh the idler wheel assembly on Ski-Doo Nordic 371 and 399 models from 1969 through 1971. The idler wheel rubber replaces worn or cracked original rubber so the track runs true and stays tensioned. It is a practical spare for riders keeping vintage Ski-Doo Nordic sleds trail ready.

Specs At A Glance

Good To Know

Q: How do I know if the idler wheel rubber needs replacing? A: Cracking, flattening, or missing chunks of rubber on the idler wheel are the usual signs, and a track that will not hold tension often points to the same cause. Inspect both sides of the suspension before ordering.

Q: Can I replace just one idler wheel rubber? A: Yes, a single worn idler wheel rubber can be replaced on its own as long as the rest of the wheel assembly is sound. It is wise to inspect the remaining idlers for matching wear.

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