5.7 Hemi Supercharger Kits (2026): Amazon Availability & Fitment
Quick answer: We could not verify a complete, vehicle-compatible 5.7 Hemi supercharger kit on Amazon as of October 2026. The Amazon results we inspected included a 3.6L Jeep kit, adapter plates and unrelated engine parts. None is a ready-to-install 5.7 Hemi kit. Use this guide to check fitment and kit contents before ordering; it does not rank unverified products.

How to Choose a 5.7 Hemi Supercharger Kit
Verify the complete kit number with the manufacturer for your exact truck or car before buying. Confirm engine, model year, body, eTorque status, fueling, intercooling, calibration and emissions application. Availability on Amazon may change, so recheck the exact listing and included components.
Essential Factors We Consider
Ram 1500 Classic, current-body, and eTorque trucks need separate fitment checks. Confirm belt hardware, intercooling, injectors, calibration, required fuel, and emissions approval. Test engine health before adding boost.
- Exact year, engine, trim and vehicle configuration
- Manufacturer-listed application and installation requirements
- Real benefit for the intended use and known limitations
- Warranty, safety, legal and maintenance implications
Budget Planning
The kit price is only the start. Add installation, tuning, supporting parts, and possible transmission or cooling work. Confirm warranty terms in writing.
Final Thoughts
Choose the exact kit for your truck and use, then discuss the build with an experienced installer. A universal compressor or lifter kit is not a substitute.
Frequently Asked Questions
Q: Can a stock 5.7 Hemi handle a supercharger?
Condition matters more than a blanket yes. Check compression, fuel delivery, cooling, transmission, and the kit maker’s limits.
Q: How much horsepower can a supercharger add to a 5.7 Hemi?
There is no single credible gain for every 5.7 Hemi. Use the kit maker’s test conditions and the installer’s expected result for your exact truck.
Q: Is it necessary to delete MDS when supercharging a 5.7 Hemi?
No automatic MDS-delete requirement follows from adding boost. Ask the kit manufacturer and tuner about your exact engine.
Q: What other modifications are needed with a 5.7 Hemi supercharger?
A complete kit may include intercooling, injectors, belt hardware, and calibration. Confirm contents before budgeting.
Q: How does a supercharger affect 5.7 Hemi reliability and longevity?
Reliability depends on engine health, tune, fuel, temperature, and use. A professional pre-install inspection is worthwhile.
Q: What’s the difference between a centrifugal and a Roots/Twin-Screw supercharger for a Hemi?
Centrifugal and positive-displacement systems have different packaging and power delivery. Compare vehicle-specific kits, not generic compressors.
Q: Can I install a supercharger myself on my 5.7 Hemi?
Follow the maker’s instructions and calibration requirements. Professional installation is sensible if you lack forced-induction experience.
