Hemi Performance Packages: Best Camshafts and Valve Springs Australia

Hemi Engine Upgrades Australia: Best Cams, Springs, and Performance Parts Online

When it comes to getting real gains out of your 5.7L or 6.4L Hemi, bolt-ons will only get you so far. If you’re chasing real performance more torque, faster launches, and better top-end pull upgrading your camshaft and valvetrain is where the real power starts.

At Independent Motorsports, we don’t just sell parts we run them, tune them, and test them on Australian roads and dynos. If you’re building a street Hemi, drag setup or a tough streeter, we’ve got the cam kits and valvetrain packages to match.

Why Hemi Camshaft Upgrades Matter

Modern Hemi engines are well-built, but factory cams are tuned for emissions, not power. A performance camshaft will:

• Improve throttle response

• Add more mid-top end power

• Enhance that classic V8 idle note

• Unlock tuning potential with supporting mods

We carry aggressive and street-friendly camshaft profiles for all late-model Hemi platforms including 5.7L, 6.1L and 6.4L.

Do You Need Springs Too?

Yes. Every cam upgrade that increases lift or duration will require a valve spring upgrade. Using stock springs can lead to coil bind, float, or even engine failure at higher revs.

We carry performance dual valve springs and matching retainers to suit popular Hemi camshaft profiles.

Supporting Mods We Recommend

• Headers and Exhausts – Free up backpressure to let the cam breathe

• High-flow intake and throttle body – Improve air delivery

• ECU tuning – Unlock full cam potential

• Phaser locks or deletes – Required for some aggressive profiles

We supply all the parts above, and can advise what works best for your build.
