DIFFERENTIAL SPOOL: This differential spool replaces the rear differential gear. The spool locks the axle, providing equal power to both wheels no matter what the truck drives over. If you’re building a Maxx truck for straight-line sand drags, hill climbing or pulling, you can replace the rear differential with a spool for increased 2WD traction.
