About HEMIS

The HEMI Specialists

HEMIS is Australia's dedicated online store for genuine and premium aftermarket parts for Jeep, Chrysler, Dodge and RAM. From a single spark plug to a complete supercharged Hellcat crate engine, every part we sell is one we know, fit and stand behind.

By American Builds

HEMIS is the parts arm of American Builds, Australia's specialist American vehicle workshop. That matters because the people behind this store build, convert and tune HEMI-powered vehicles every day. We're an AMW4x4-certified HEMI conversion partner, an authorised FOX suspension distributor, and part of an authorised Stellantis dealership network, which is how we supply genuine Mopar parts with full factory backing.

Genuine and aftermarket, honestly sold

We sell genuine Mopar parts where factory is the right answer, and premium aftermarket where it outperforms. Every listing tells you which is which, what it fits, and how many you need for the job.

Australia-wide supply

We ship genuine and performance parts across Australia, from Melbourne and Sydney to regional WA, supporting retail enthusiasts and trade workshops alike. Trade accounts with dedicated pricing and 30-day terms are available for workshops; see our Trade Accounts page.
