Product Description
Traxxas 4981X Spool T-Maxx
Spool eliminates differential; use off-road only. (Requires #4981 ring gear) 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.
