Matching ratio to carrier
A carrier rating tells the gear set which ring gear geometry and bearing setup it was built to suit. A set rated for a lower carrier can need a different mounting arrangement, so the carrier rating and gear ratio should be confirmed together before the set is ordered. Mixing mismatched parts can make the gears run noisy or wear unevenly.
Lower-geared sets like a 5.13 are common where the vehicle is used at moderate speeds, but tire size and the engine’s power band both affect how the gearing feels. After installation, check the contact pattern and backlash, then recheck bolts and the carrier cover torque after the first few drives.
- Confirm the carrier rating first
- Check tire size before choosing a ratio
- Recheck torque after the first drives
