V3 version comes with 3x6x2.5mm Thrust Ball Bearing

• Light weight. Minimal rotational inertia for fast acceleration.
• The axle has been revised to 3mm (both sides use the same size bearing/bushing now)
• Fast gear ratio changes. No disassembly of the differential is necessary for a spur gear change.
• Adjustable side gear tension for tight or loose differential action.
• Smooth quiet operation. No gear noise and vibration associated with stock differential
• With the Enclosed case, Racers can add diff grease to fine-tune diff action, the covers also help reduce dust and particles on diff gears therefore less maintenance.
• Comes with the newest Brass Spyder Gear (MR2055B) for ultra-smooth action
• Do Not Come with Pinion Gears (you will need 64P Pinion gears of your choice)

Changing Spur Gear Ratio:

1. Remove 3 screws on the covers and remove both covers
2. Loosen the Tension Nut to separate the side gears
3. Allow spider gear pins to recess into the carrier. Depress with a screwdriver if necessary, as shown by the arrows
4. Remove the spur gear
5. Installation is the reverse of removal
