What is the axle ratio of a scat pack?
The axle ratio most Scat Pack models use is 3.07:1, a final-drive setting that balances quick off-the-line acceleration with reasonable highway cruising. The exact figure can vary by year, transmission choice, and optional equipment, so it’s best to verify your specific vehicle if you need a precise number.
Understanding what the Scat Pack is and why the ratio matters
The Scat Pack is Dodge’s performance-focused package built around the 6.4-liter Hemi V8. The rear axle ratio, or final-drive ratio, determines how engine torque is translated into wheel rotation. A lower numerical ratio (like 3.07:1) generally provides quicker initial acceleration but higher engine speeds at highway speeds, while a higher numerical ratio would slow initial acceleration but lower engine RPM at cruising speed. For most Scat Pack configurations, Dodge has favored a compact, sporty final drive to deliver a blend of punchy launches and tolerable highway economy.
Typical guidance for axle ratios
For the Scat Pack, the standard final-drive ratio is 3.07:1. Production variations by year, drivetrain (manual vs. automatic), and optional packages can yield slight deviations. To be certain for your specific car, verify the exact ratio using official documentation or the vehicle’s build information.
How to verify your car’s exact axle ratio
Because the axle ratio can change by year or option, the quickest way to confirm is to check the car’s official documentation or the vehicle itself.
To confirm the exact axle ratio for your car, follow these steps:
- Check the door jamb sticker or the glove box/striker plate for a "Rear axle" or "Final drive" figure.
- Review the window sticker or the original build sheet (sometimes called a RPO or VIN-specific spec sheet) from when the car was new.
- Use the VIN to pull the original specifications from the manufacturer’s portal or through your dealer’s system.
- Consult the owner's manual or the dealer invoice if you have access to the original paperwork or PDF build documents.
Concluding note: These sources will give you the exact axle ratio for your particular Scat Pack, which is essential for performance tuning or maintenance records.
