Ultra Track front idlers are crafted for a precise fit and dependable operation, matching OEM standards for quality and reliability. These rugged, single flange tension idlers feature advanced double lip seals to lock in lubrication and block out dirt and debris—helping your equipment run longer with less downtime.

They install directly onto the tensioner or track adjuster, keeping your rubber tracks properly tensioned under tough working conditions. If your tensioner is maxed out and the track still sags, the idler may be worn and due for replacement.

To protect your investment and get the most from your undercarriage, we recommend inspecting related components during regular service and replacing parts as needed.

Ultra Track offers a full lineup of undercarriage essentials tailored to your machine—rubber tracks, sprockets, rollers, and more—to keep you moving forward with confidence.
