450 Rear Axle Differential- Segway Powersports - AT5S / AT5L

This SKU (Q02-R000000-000-00) is the factory part number for the complete 450 Rear Axle Differential Assembly.

If your diagnostics reveal that the center prop shaft is turning perfectly but the problem is entirely internal (such as sheared ring and pinion teeth or a cracked planetary gear setup), this complete housing is the drop-in replacement part you need.

🚙 Vehicle Compatibility

• AT5 S (Short Wheelbase Versions): Yes, this is a 100% direct factory fitment across all standard short-chassis AT5 models equipped with an unlocked rear differential.

• AT5 L (Long Wheelbase Versions): Yes. Just like the outer CV wheel axles, both the short and long versions of the AT5 share the exact same rear gear setup and track width, meaning this unit bolts perfectly into either frame size.

⚙️ What is Included in This Assembly?

When you order this part number, it arrives as a pre-sealed unit housing all the complex internal gears that handle power distribution to your back tires. It includes:

• The core Drive & Driven Bevel Gears (the Ring and Pinion set).

• The internal Planetary Gears, planetary shafts, and half-shaft bevel gears.

• The entire internal Differential Housing carrier assembly.

• The internal Shift Fork mechanism and transmission pawl components responsible for active differential locking.

🔧 Pro Tip For Your Repair

Replacing the entire differential block as a whole unit is significantly faster than trying to rebuild one. Rebuilding a blown differential requires meticulously measuring gear backlash and calculating shim thickness to prevent the gears from grinding themselves to pieces. Unbolting the old housing completely and dropping this factory-sealed unit in its place cuts down a frustrating, all-day job into a straightforward swap out job.
