Description
Replacement tensioner idler bearing for Whipple Superchargers. We recommend servicing these every 80,000 miles to prevent failure as they are a custom idler. Sold individually.
Notes: There are two versions.
- G1 has just an idler on the tensioner.
- G2 has two idler pulleys.
We have also seen idlers take 1 or two bearings per idler. Inspect before ordering to make sure you order enough.
Note: If you send your tensioner and idlers in, we provide this service for minimal labor (under 10 minutes).
