SWORKz reaches a new dimension of acceleration with the HET Diffs. New geometry of gears and surfaces leads to that result.
This new option for the SWORKz 1/8 Series Servo Saver Nut is a specially designed with a screw lock. Now It will be much easier to tighten the servo saver nut and lock it on to the servo saver post. With the screw tighten and fixed, there will be no change in the servo saver spring position during the race.
