Through intensive testing with different size balls we have determines that as strange as it sounds the outside pod ball size makes a significant difference in how the car handles so what we have done is split the difference between. The std kit balls are small and these ball studs are sized in between the small and what we felt was too big. The center ball now has the spacer built in and more thread length.
2024 spec shock plastics
damper shaft eyelets now screw on instead of glue on
damper tube ID is smaller so now you use 15k grease instead of 30 only
center shaft is set for 15 or 30k (30k recommended)
work better with RF-BS-352 ballstud shock kit
One set in a bag
It is custom-size order from the manufacture
The large diameter ring is put inside of the ball diff or gear diff, and the small on put outside
V3 version comes with Thrust Ball Bearing (
PN-600126T 3x6x2.5mm)
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:
Remove 3 screws on the covers and remove both covers
Loosen the Tension Nut to separate the side gears
Allow spider gear pins to recess into the carrier. Depress with a screwdriver if necessary, as shown by the arrows
Remove the spur gear
Installation is the reverse of removal

Install Cover
Insert Outer Cover (with see through screw hole) in Spur Gear Groove (wheel side) and line up the screw hole with the spur gear
Insert Inner Cover (screw hole can't see through) in Spur Gear Groove (shaft side) and line up the screw hole with the spur gear
Install 3 screws, gently tighten diagonally (Thin Plastic can strip easily, Do Not Over Tighten)
