- Drive slugs are manufactured out of 4340 chromoly steel and heat treated AFTER machining. This provides a much stronger design than simply working with preheat treated material.
- Flange cover bolts DON'T attach to the drive slug. This way, you have the option of running the flange cover without running the drive slug.
- All manufacturing is done in-house, allowing for superior quality control over the competition.
The Spidertrax 4340 35 Spline Drive Flange Kit is specifically designed for use with the Spidertrax 1 Ton Unit Bearing. Shipping weight per kit is only 5 pounds with one kit working for two unit bearings.
