Found an unmarked driveshaft in the workshop, or holding a bent one from a Ural-4320? The driveshaft 375-2203010-05СБ (Russian: карданный вал) is the front-axle drive shaft of the Ural-375 and Ural-4320 6x6 trucks — and it is one of those parts you can positively identify with nothing but a tape measure and a caliper. This guide gives you the full dimensional fingerprint.
What this driveshaft does
On a URAL 6x6, the transfer case sends torque forward to the steered, driven front axle through this shaft. Because the front axle moves with the suspension and turns with the steering, the shaft works through bigger angle changes than any other shaft in the drivetrain — which is why it uses square flanges and a generous sliding section. The catalogue records +90 mm of travel in the splined section, letting the shaft grow and shrink as the axle articulates.
When this shaft's universal joints or splines wear, you get the classic symptoms: vibration that changes with steering angle, clunks when engaging front-wheel drive, and driveline shudder under load off-road.
The dimensional fingerprint
This is where the 375-2203010-05СБ is easy to verify. From the OEM catalogue:
| Dimension | Value |
|---|---|
| Part number | 375-2203010-05СБ (also written 375220301005СБ) |
| Length | 1167 mm (+90 mm sliding travel) |
| Weight | 22 kg |
| Flange type | Square, 4 holes × ⌀14 mm |
| Spider (cross) size | 39 × 118 mm |
| Tube | 71 × 3 mm |
If your unmarked shaft matches length 1167 mm, spider 39×118, tube 71×3 and square 4-bolt flanges with 14 mm holes — you are holding a 375-2203010-05СБ.
Which trucks does it fit?
Two models, the heart of the URAL 6x6 family:
- Ural-375 — the classic petrol V8 military truck
- Ural-4320 — the diesel 6x6 successor, still in production decades later
Why the suffix matters: -05СБ
As with all URAL drivetrain parts, quote the full number:
- 375-2203010-05СБ — this complete assembly (СБ = сборка, assembly)
- Other suffixes under 375-2203010-xx exist for different build variants
"375-2203010" alone is ambiguous. The suffix fixes the exact configuration — flange pattern, length and balance spec — and saves a wrong-shipment argument later.
Before you order
- Match the full number 375-2203010-05СБ against your parts book.
- Verify with the dimensions above — especially length and spider size, the two fastest checks.
- At 22 kg per shaft, these ship best as mixed pallets with other drivetrain parts for wholesale orders.
