- Light weight spool
- 30 spline
- Rear Dana 44 position
Choosing gears for a spool
Gear ratio is the main decision when adding a full spool. Lower numeric ratios suit highway driving, while higher ratios such as 3.92 and up give more torque at low speed for trails and heavier tires. Pick a ratio that matches how the vehicle is driven and the tire size it runs.
A spool also changes how the axle behaves when the tires are not even on the ground. Because both wheels turn together, the drivetrain can bind on tight turns on pavement. Many drivers keep the spool for trail use and drive with the axle open on the street. Check the ring gear, pinion and carrier bearings for wear at the same time you install the part. Keep spare fasteners and a torque wrench on hand for the first few drives.
- Match the spool to tire size and driving style
- Inspect ring gear and pinion before installing
- Keep the axle open for daily street driving
