I ordered the Dodge RAM HEMI ATI/MMX Super Damper for my imported RAM in Australia, and Dodge Auto Supply delivered excellent service. Ordering was easy, and the product information was accurate. Shipping was efficient, and the part arrived in perfect condition. The damper is built to a very high standard, with excellent machining and solid materials. After installation, the truck gained stronger boost response and more aggressive power delivery. The 8-rib setup improved belt grip significantly, and everything feels much more reliable under heavy load. I’m very happy with this upgrade.

I ordered the Dodge RAM HEMI ATI/MMX Super Damper 8-Rib from Dodge Auto Supply for my 2021 RAM 1500 supercharged build, and the entire experience was excellent. The website clearly explained the 6% and 18% overdrive options, which made choosing the right setup easy. Checkout was fast and secure, and I received order confirmation immediately. Shipping updates were consistent, and the package arrived earlier than expected. The Super Damper was packaged securely and looked extremely high quality right out of the box. The ATI machining and MMX engineering are top-notch. After installation, boost came on harder, and throttle response improved immediately. The 8-rib setup provides much better belt grip, especially under heavy load. The truck now feels stronger across the RPM range, and the supercharger setup is far more stable. Dodge Auto Supply delivered exactly what was promised.

I purchased the Dodge RAM ATI/MMX Super Damper for my 2020 RAM Rebel, and I’m extremely impressed with both the product and Dodge Auto Supply’s service. The website made it easy to understand the difference between the 6% and 18% overdrive options. Shipping was fast, and the package arrived safely. The quality of the damper is outstanding—precision-machined and built for serious power. After installation, my supercharger setup became much more efficient. Boost builds quicker, and the truck feels stronger throughout the entire powerband. The belt grip is much better with the 8-rib conversion. This is one of the best upgrades I’ve added.

This was my first time ordering from Dodge Auto Supply, and I’m impressed. I installed the ATI/MMX 18% Overdrive Super Damper on my 2022 RAM 1500, and the difference is huge. The ordering process was simple, shipping was quick, and the part arrived in perfect condition. The build quality is top-tier, and installation was straightforward. After driving the truck, I noticed stronger boost, faster throttle response, and more aggressive acceleration. The 8-rib setup holds power much better with no belt slip. This is one of the best upgrades I’ve done for my boosted HEMI.

The 8-rib design also eliminated belt slip under hard acceleration. This upgrade is perfect for anyone running boost.
