Bulletproof Differential Spool - 7075 Billet Aluminum.
Differential "lunchbox" spool, Billet 7075 Aluminum.
Precisely CNC machined from Billet (7075-T6 Aluminum) to fit factory Differential case (AR310433, or aftermarket Aluminum ones) mating precisely with the Spur Gear (AR310429) or Main Diff gear (AR310497), Steel Outdrives (AR310439) & Factory Pins (AR310440). Note: Advanced Engineered using low tolerances to provide the best possible fitment and minimal possible "slop" to all Stock Arrma components such as Pins (AR310440 PIN 2.25X9.8MM) & Steel Diff Outdrive (AR310439) so pin breakage or wearing down other diff components doesn't occur in our superior Bulletproof RC brand!
Each Spool is Individually balanced and designed to endure massive centripetal force under speed runs. Weighs just under 1 oz. & is engineered to easily swap in and out with factory differential components going from unlocked to a completely locked setup in a matter of minutes.
Completely locking differential forces both left and right wheels on the same axle to rotate at the same speed under all circumstances, without regard to tractional differences seen at either wheel. A locked differential can provide a significant traction advantage over an open differential, but only when the traction under each wheel differs significantly. IDEAL For On/Off Road Speed Runs and/or Specific stunts. Fits all three differentials (Front ARA310957, Center ARA310959 and Rear ARA310957). Replaces internal differential components (AR310436) completely locking it up.
*100% satisfaction guaranteed and reliability backed with our lifetime replacement warranty.*
**Install with factory gaskets/seals & washers for the correct fitment.**
