Featured: Scania GRS 905 Main Shaft Assembly
The main shaft assembly is the heart of the Scania GRS 905 heavy-duty range gearbox — and one of the most demanding components to rebuild correctly. Our workshops carry the complete OEM-quality main shaft assembly, including gears, synchronisers, bearings and matched components, ready for immediate fitment or supplied as a complete rebuild kit.
Each main shaft we supply is sourced from our trusted European suppliers (Euroricambi, FAG, Fersa, INA, SKF and Timken) — the same OEM-tier brands that supply Scania directly. We can also rebuild your existing main shaft assembly using ISO 9001 approved replacement parts that are of the highest quality, which is time saving and cost effective without compromising on reliability and durability.
