Ordering URAL transfer-case flanges, you will run into two almost identical part numbers: 375-1802264 and 375-1802264-Б (Russian: фланец). Same name, same weight, same analog code — so which one does your truck need? This guide breaks down the base flange 375-1802264: what it does, which trucks take it, and how it relates to its -Б sibling.
What this flange does
Flange 375-1802264 is the square front-axle drive flange of the URAL transfer case, and the same design is also fitted on the axle reducer. It transmits torque from the transfer case to the front-axle drive shaft — the coupling point that makes a Ural a 6x6.
Living at a torque transfer point, the flange's spline bore and bolt-hole faces are wear items. Off-road shock loads, u-joint vibration and hard clutch engagement all work on them, so flanges are regular inspection items on military-spec URAL trucks.

Which trucks does it fit?
Three URAL 6x6 models:
- Ural-375 — the classic petrol V8 military truck
- Ural-4320 — the diesel 6x6 successor, still one of the most common off-road trucks in service
- Ural-5557 — 6x6 chassis for special bodies
375-1802264 vs 375-1802264-Б — which one do you need?
This is the question that trips up parts buyers:
- 375-1802264 (this part) is the base drawing number, catalogued for the Ural-375, 4320 and 5557.
- 375-1802264-Б is a variant of the same flange (the Cyrillic suffix marks a design version). It appears on 31 assembly drawings including later Ural-4320-31 applications — on that truck's final-drive reduction gear through-shaft drawing it is even listed with a quantity of 3 per vehicle.
Both share the same role, the same ~1.89 kg weight and the same analog code AR18-001-0036, and in practice the two are treated as interchangeable by most suppliers. But parts books are strict about suffixes, so the safe procedure is:
- Match the exact catalogue number — with or without the -Б suffix — against your vehicle's parts book.
- Cross-check against the analog AR18-001-0036 if your supplier uses that code.
- If your parts book and the old part disagree, send the number plus a photo of the old flange and your truck model to the supplier before ordering a batch.
