Ultra Track Rear Idler – Restore Track Tension and Stability. Ultra Track rear idlers are designed to deliver reliable performance and a precise fit, matching OEM specifications for your equipment. Built with durable materials and sealed with high-quality double lip seals, these idlers keep out dirt and debris while retaining lubrication—ensuring long-lasting operation in rugged conditions. The rear idler plays a crucial role in maintaining proper track alignment and tension. When worn, it can reduce track tension and cause issues like rear de-tracking or premature wear on other components. If your tensioner is fully extended and slack remains, it’s often a sign the rear idler needs replacing. To extend the life of your undercarriage, we recommend inspecting all track components during routine maintenance and replacing worn parts together.
