Frequently Asked Questions
What does 5% overdrive mean?
The pulley spins accessories and superchargers about 5% faster than stock, resulting in increased boost and performance gains in forced-induction applications.
Will this fit 6.4L VVT engines?
No. The ATI918432 is designed for non-VVT HEMI engines only (6.1L, 392, and 426 built between 20052010). VVT models require a different ATI damper.
Is it suitable for supercharged or naturally aspirated setups?
Yes. This damper is ideal for both boosted and NA builds, delivering consistent harmonic balance and improved response regardless of configuration.
Is it rebuildable?
Yes. Like all ATI Super Dampers, the ATI918432 is fully rebuildable using factory service components for continued precision and longevity.
