RAM TRX Stage 2 Performance Package
Stage 2 takes everything in our Stage 1 package and goes further. It improves how the supercharged Hemi breathes on both the intake and exhaust sides and adds a fuel system upgrade to support the extra demand. The result is a big step up in power and torque, delivered as one complete, dyno-tuned package.
What's Included
Supercharger Pulley and Belt
A smaller-diameter supercharger pulley spins the blower faster, which increases boost. It's machined from billet 7075-T6 aluminium and has a grip-textured surface that holds the belt firmly without causing premature wear. A new belt is fitted with it.
160-Degree Thermostat
The 160-degree thermostat opens earlier than the factory unit. That keeps engine temperatures lower and helps the TRX hold its power when it's being worked hard. It's a direct replacement and fits with no modifications.
aFe Magnum Cold Air Intake
A supercharged engine is only as good as the air it can draw in. The aFe Magnum intake replaces the factory airbox with a high-flow, heat-shielded system that feeds the supercharger cooler, denser air. Its oil-free dry filter is washable and reusable, which keeps maintenance simple.
Manta Headers and High-Flow Catalytic Converters
We replace the factory manifolds with Manta's 4-into-1 headers, which have 1¾" primaries. They're matched to high-flow catalytic converters. This combination reduces exhaust restriction right at the source, so the engine can make the most of the extra boost.
Manta Twin 3" Cat-Back Exhaust
This Australian-made system completes the exhaust upgrade. It uses twin 3" pipework, an H-pipe and free-flowing mufflers, and it's finished with 5" tips in your choice of chrome or black. It delivers a deep V8 note to match the performance.
Excess XS1500 Fuel Injectors
More air and more boost require more fuel. We fit a set of eight 1500cc injectors from Excess Fuel Injectors, which are tested and flow-matched in Melbourne. Precise flow matching across all eight cylinders gives consistent fuelling and smooth drivability, and the injectors have plenty of headroom for future upgrades.
Custom Dyno Tune
With the hardware fitted, we calibrate boost, fuelling and ignition timing on our 4WD dynamometer for 98 octane fuel. This is what brings the package together: every component works in harmony, and the gains are delivered safely.
How It Works
Baseline Assessment
Every TRX starts with a baseline run on our 4WD dyno. This confirms the vehicle is healthy before any work begins and gives us a stock figure to measure against.
Installation and Tuning
Our technicians fit the Stage 2 components, then tune the vehicle on the dyno to get the most out of the new hardware.
Road Testing and Refinement
Once dyno tuning is complete, we road test the TRX and make final adjustments so it drives as well as it performs in everyday conditions.
Your Results
At completion, you'll receive a dyno graph showing your TRX's power and torque before and after the upgrade.
