Product Details

The ARB 728J031C Internal Gear Set is a complete replacement gear kit designed specifically for the ARB RD105 Air Locker differential. This kit includes the spider gears, side gears, pins, and C-clips necessary to rebuild or repair your ARB Air Locker.

Key Features:

  • Designed for ARB RD105 Air Locker (Dana 35, 30 spline, 3.54 and up gear ratios)
  • Complete kit includes spider gears, side gears, J1 pin, and C-clips
  • Forged gear construction for maximum strength and durability
  • OEM ARB replacement part ensuring proper fit and function
  • Includes all components needed to service internal differential gears

This internal gear set is essential for maintaining your ARB Air Locker's performance. The spider and side gears can wear over time or become damaged during extreme off-road use, and ARB designs these components as a complete kit to ensure proper meshing and operation. Professional installation by a qualified differential technician is recommended for proper setup and backlash adjustment.

Online it didnt say anything about the tires being tube type which woulda been nice to know instead of finding out after i got the tires.

No problems. Delivered as ordered.

Easy to order

Thank you. Hope the part is the right one! Very easy transaction!

it was very quick and eas to order online

Paypal checkout was clunky - probably because I had to update an address - wouldn't let me login - mostly Paypal stuff

Easy

Prompt shipment, I got everything under 5 days even if part of my order was drop shipped (in stock items arrived in 2 days). Good communication, would do business again in a heartbeat.

I will definitely do more shopping with Autoplicity....great prices and quick shipments.
