RAM 1500 TRX Supercharger Service Packages Explained

The RAM 1500 TRX runs a 6.2L supercharged HEMI — the same Hellcat-derived engine that powers the Challenger SRT Hellcat, Charger Hellcat, and Durango Hellcat. If you own a TRX and you’re wondering whether the supercharger work FAS does on Hellcat platforms applies to your truck, the answer is yes. Same IHI 2.4L unit, same service model, same 3–5 business day ship-in turnaround.

This post breaks down what each service package covers, when it makes sense, and what the process looks like from your garage to ours.

The TRX Supercharger Platform

The 2021–2024 RAM 1500 TRX uses a 6.2L supercharged HEMI rated at 702 hp and 650 lb-ft of torque from the factory. The supercharger itself is an IHI-style twin-screw 2.4L unit — the exact same platform used across the Hellcat lineup since 2015. That shared architecture is what makes TRX service work straightforward for a shop already set up for Hellcat IHI work.

The factory blower is engineered for emissions compliance and broad torque delivery across the RPM range. That’s not a criticism — it’s why the TRX is as livable as it is as a daily driver and weekend truck. But the same engineering compromises that make it smooth leave airflow restriction on the table that porting can address.

Service Package Breakdown

Porting (Standard)

The most common entry point for TRX owners. We remove the supercharger assembly, port the case and snout for improved airflow, clean and inspect internal components, and return the unit ready to reinstall. Typical turnaround is 3–5 business days from receipt.

Best for: TRX owners looking to extract more airflow from existing hardware before or alongside supporting modifications. Works well combined with a lower pulley, catch can, and supporting injectors.

Rebuild (Bearings + Seals)

Adds a full bearing and seal replacement to the service. If your TRX has higher mileage, has gone through a hard season, or shows bearing noise at full boost, this is the appropriate step.

The rebuild package includes OEM-spec or upgraded bearing sets, new seals throughout, and a reassembly torque check before shipment. We document the condition on teardown and include a condition report with every rebuild.

Combo: Port + Rebuild

The complete service path. Port the case and snout for airflow, replace bearings and seals, inspect the full assembly, and ship back documented. Recommended if the unit is going into a higher-power combination or is due for a refresh regardless.

The Ship-In Process

1. Contact FAS to confirm availability and get shipping instructions.
2. Remove the supercharger assembly and package it securely — we'll send handling guidelines if this is your first ship-in.
3. Ship to FAS Motorsports, 6161 Riverside Dr, Punta Gorda FL 33982.
4. We receive, inspect, document, and begin the service.
5. Finished unit ships back with a condition report, torque specs, and reinstall notes.

Estimated turnaround after receipt: 3–5 business days for porting; 5–7 for full rebuild; 5–7 for combo depending on parts availability.
