Dedicated Motorsports Wide LT4 Tensioner Pulley (76108000025) - 2016-2019 CTS-V / 2017-2024 Camaro ZL1 / 2015-2019 Corvette Z06
The DMS Wide LT4 Tensioner Pulley is the solution to belt squeal, chirping, or rib separation issues common with factory LT4 setups. OEM pulleys often allow side?to?side movement that leads to misalignment and premature wear. This upgraded design improves belt tracking, enhances stability, and eliminates noise for a more reliable supercharger drive system.
Why Upgrade?
- Corrects Belt Misalignment: Dual?row bearing design prevents radial movement that causes belt walk.
- Protects Against Belt Damage: Wider pulley surface keeps the belt centered, reducing rib loss and wear.
- Quiets Operation: Eliminates squeaks and chirps caused by unstable OEM pulley design.
Key Features

- 42mm wide design - 10mm wider than stock for improved belt stability
