Clutch Master Cylinder for GAZ GAZon-Next Truck 2014– – C41R11-1602300

GAZon-Next — Russia's Most Widely Used Medium-Duty Truck
The GAZ GAZon-Next is a medium-duty truck produced by GAZ Group in Nizhny Novgorod, Russia. Launched in 2014, it replaced the earlier GAZon series as GAZ's core commercial vehicle offering in the 3.5–8.7 tonne payload segment. The GAZon-Next is used across construction, municipal services, agricultural logistics, and intercity freight in Russia, Kazakhstan, Belarus, Ukraine, and other CIS markets.
The clutch system on the GAZon-Next is hydraulically operated. C41R11-1602300 is the master cylinder at the top of that circuit — it converts pedal input into hydraulic pressure that travels to the slave cylinder, which then disengages the clutch for gear changes. On a truck doing repeated stop-start work with heavy loads, this component cycles thousands of times a day. Seal integrity and consistent fluid flow are what keep the pedal feel predictable and the drivetrain responsive.
Failure signs on this platform are consistent with other hydraulic clutch systems: a pedal that sinks gradually, difficulty selecting gears under load, or fluid loss near the firewall. Replacement is straightforward, but sourcing the correct part outside Russia requires knowing the OE cross-references.

Why Renault-Style OE Numbers Appear on a Russian Truck
The GAZon-Next was developed using Renault technology under a technical cooperation agreement signed between GAZ Group and Renault. The engine — a Cummins ISF or YaMZ unit depending on specification — and several drivetrain components were sourced or co-developed under this framework. Parts numbering in some catalog systems reflects this lineage, which is why 306202804R and 306203814R carry the same prefix format as Renault commercial vehicle OE numbers.
This matters for parts sourcing. Buyers searching Renault-format numbers in European aftermarket databases may encounter this reference in unexpected contexts. Understanding the platform background prevents catalog mismatches and helps distributors position the part accurately in both CIS-focused and European export catalogs.

Q1: Why do the OE numbers (306202804R, 306203814R) look like Renault part numbers?
GAZ Group used Renault-derived technology and numbering conventions on several GAZon-Next drivetrain components. The R-suffix format follows Renault's parts system structure. Both numbers are valid GAZ OE references for this application.

Q2: What is the difference between 306202804R and 306203814R?
These are parallel OE references that appear in different catalog versions or production batches. Both cross to the same master cylinder. If one number returns no results in a database search, the other will confirm the fitment.

Q3: Does C41R11-1602300 fit all GAZon-Next variants produced from 2014 onward?
The part covers the GAZon-Next platform from 2014. GAZon-Next has been updated through several production revisions — always confirm against the vehicle's current OE number before ordering, particularly for post-2020 units.

Q4: Is the plastic housing suitable for the operating conditions of a medium-duty truck?
Yes. The housing is manufactured from reinforced plastic rated for the hydraulic pressures of a commercial vehicle clutch system. The material specification is consistent with OE production and has been validated for the load cycles typical of medium-duty truck operation.

Q5: Is this part available for export outside Russia and CIS markets?
Yes. This is an export-ready SKU. Standard international packaging applies, and OEM/ODM options are available for buyers requiring custom branding for specific regional markets.
