This steering wheel spinner knob is designed for use on site dumper steering wheels, allowing operators to turn the wheel quickly and efficiently using one hand. Often referred to as a steering wheel knob or suicide knob, it improves manoeuvrability when operating dumpers in tight spaces, loading areas and confined construction sites. The spinner knob attaches directly to the steering wheel rim, providing extra leverage and faster steering response during repetitive site movements.
Compatible with a wide range of Terex, Mecalac and Thwaites dumpers, this spinner knob is commonly used on machines ranging from 1-ton compact dumpers through to 10-ton articulated dumpers. Designed for durability in demanding site environments, it helps reduce operator fatigue while improving control during tipping, reversing and tight turning operations. Matching Terex OEM part numbers 6106163M91 and 1731-1212A and Thwaites part number T52520, it provides a reliable replacement for damaged or worn spinner knobs used across plant hire fleets, construction contractors and equipment service teams. Available from HTS Spares.
