Rear diff ring and pinion kit

This 3pcs aftermarket differential gear set is made for TRAXXAS MAXX rear differentials, replacing the stock rear ring and pinion with hardened steel #45 pieces and including a stainless steel retaining pin.

The harder #45 steel improves resistance to wear in high-load use, and the closer tolerances reduce backlash so power delivery feels smoother and engagement is more repeatable. These traits help when fine tuning preload or diagnosing gear rattle.

Fitting tips: open the differential case per your chassis guide, swap the ring and pinion, check the alignment of the retaining pin and endplay, then verify gear mesh by hand rotation before sealing the unit. Apply threadlocker or retaining method suitable for RC parts if needed.

Packing includes

  • Ring Gear - 1pcs
  • Pinion Gear - 1pcs
  • Stainless Steel Pin 2.5x13 - 1pcs

How does hardened #45 compare to stock material?

Hardened #45 is a carbon steel grade that, when heat treated, offers better wear resistance than softer stock gears, improving longevity for aggressive driving.

Is any break-in required for these gears?

A short, gentle running session with the installed gears and proper lubrication helps seat the teeth and confirm mesh; avoid heavy loads until you verify smooth rotation.

What is included in the kit?

The kit contains one ring gear, one pinion gear, and a 2.5x13 stainless steel retaining pin for the differential assembly.
