Sollers ST9 Transfer Cases Enter Serial Production in Russia

Sollers ST9 Transfer Case Production Begins

Sollers ST9 transfer cases have entered production following the announcement by Sollers Transmission Production on September 7. The new electromechanical transfer cases are intended for Sollers ST9 pickup trucks and represent an upgraded version of units already produced by SOLLERS Group. The production development adds another locally manufactured component to the ST9 program while retaining a design lineage from existing transfer-case units. The announcement identifies the transfer case as a dedicated development for the ST9, with several structural differences compared with the components used on the ST6 and ST8 models.

Updated Design Differs From ST6 And ST8 Units

The new transfer case shares its basic development background with existing units produced by SOLLERS Group, but its design has been modified for the Sollers ST9. In particular, the ST9 version differs from the ST6 and ST8 transfer cases through changes to the front housing and input shaft, along with several associated components. These modifications distinguish the new unit from earlier versions while maintaining its role within the vehicle's transfer-case system. The announcement does not provide additional technical specifications for the revised components, so the stated design differences remain the key disclosed technical details.

Production Project Received Industrial Development Support

Serial production of the transfer cases was started in the Zavolzhye region in 2025 with support from the Industrial Development Fund. The project received more than RUB 350 million through a preferential loan provided by the fund, establishing financial support for the production program. The funding was directed toward the project behind manufacturing the transfer cases, while the September 7 announcement confirms the start of production for the upgraded ST9 unit. The disclosed investment figure provides a measure of the financial scale associated with developing and establishing this transfer-case manufacturing capability.

ST9 Program Expands Local Component Production

The start of production gives the Sollers ST9 program a transfer case specifically adapted to its design requirements while building on units already manufactured by the group. The component's differences in the front housing, input shaft, and related parts indicate that the ST9 required changes from the transfer cases used in the ST6 and ST8. Manufacturing activity in Russia, supported through the Industrial Development Fund, also connects the component program with the broader effort to establish production capacity in the region. Further details on production volumes, supplier participation, and future applications were not provided in the announcement.

Industry Impact & Outlook

The transfer-case program strengthens the component manufacturing base supporting the Sollers ST9 and demonstrates continued development of vehicle-specific drivetrain hardware within Russia. For Sollers, producing an upgraded transfer case tailored to the ST9 can support integration of the component with the pickup's requirements while building on an existing manufacturing platform. The Industrial Development Fund's preferential financing also highlights the role of development funding in establishing regional automotive production projects. The immediate next step is continued serial manufacturing, while the announcement leaves production volumes, additional localization measures, and any future expansion of the transfer-case range unspecified.
