Frequently Asked Questions

What does a 10% overdrive damper do?

The 10% overdrive pulley spins the supercharger or accessories 10% faster than stock, resulting in more boost and improved performance for supercharged or tuned HEMI engines.

Is this damper compatible with all 5.7L HEMI engines?

No. This damper fits non-VVT 5.7L HEMI car engines from 2005–2008. It is not compatible with 2009+ VVT models or truck engines.

Will this affect daily drivability?

Not negatively. While it increases performance under load, the ATI918436 maintains smooth, factory-like operation for daily driving when properly tuned.
