Featured: Fuller RTLO 18918 Counter Shaft
The RTLO 18918 is the eighteen-speed Fuller box at the heart of a great many South African long-haul fleets. The output and auxiliary counter shafts carry the load through the back half of the box, and they are where a correct, matched rebuild matters most. We supply the complete assembly, including the shafts, gears, bearings and matched components, ready for immediate fitment or supplied as a complete repair kit.
Each counter shaft we supply is sourced from our trusted European suppliers (Euroricambi, FAG, Fersa, INA, SKF and Timken) — the same OEM-tier brands that supply Fuller directly. We can also rebuild your existing counter 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.
