Show original supplier description
The ATI Performance VMP-ATI-10R-10OD is a 10-rib overdrive harmonic damper, co-designed by VMP and ATI for enhanced performance in 2020+ GT500 5.2 L and 5.0 L engines. This damper features a 10% overdrive, increasing boost by approximately 2 psi. It incorporates a new dual "lip" design and has belt alignment standardized with the 2020+ GT500. The inertia ring has been moved closer to the front main bearing to reduce stress on the crankshaft. This damper is made in the USA. Compared to the stock Coyote, this damper is positioned +1 back and +3 ribs forward. Relative to the 2020+ GT500, it's +1 rib back and +1 rib forward. It is specifically designed for VMP Supercharged Coyote engines with a 10-rib kit and 2020+ GT500 models with a 10-rib kit. It may fit 11-21 Coyote engines with a new-style 8/10 rib kit, but requires a 4-rib accessory belt (KR3E-6C301-CA) and a super-low profile accessory tensioner (VMP-SUT005). Important fitment and usage notes: this is a 10-rib version and is not recommended for use with 8-rib belts, as it may jump due to the absence of a lip. It is not compatible with older VMP 8-rib 5%, 15%, and 25% systems. This product is for closed-course competition use only and may be illegal for street use under the Federal Clean Air Act.
