- Eliminates differential
- Off road only. Perfect for rock crawling, straight-line drags, pulling and more
- Locks the axle for equal power distribution
- Can be used front and rear for total 4WD traction
This differential spool replaces the Revo differential gears. The spool locks the axle, providing equal power to both wheels. For straight-line sand drags, rock climbing, or pulling, you can replace both the front and rear differentials with spools for total 4WD traction. On tight off-road tracks, install a spool in the rear diff case to allow the rear end of the truck to rotate more easily and slide through the corners. Corrosion-resistant finish and tough steel construction ensures lasting durability.
