OTK Steering Column Standard 470mm / 490mm

The OTK Steering Column Standard (part number 0005.BA8) is a genuine OTK replacement steering column for Senior kart chassis across the full OTK Kart Group range. Available in two lengths — 470mm and 490mm — it replaces a worn, bent or damaged steering column and restores the steering system to factory specification. The standard column is the correct choice for the majority of Senior OK and KZ chassis setups; longer column options exist for specific ergonomic configurations but the 470mm and 490mm remain the most commonly fitted lengths across current OTK chassis generations.

The steering column is the primary mechanical link between the steering wheel and the front stub axles. Condition of the column directly affects steering precision and driver feedback. Any column that has been bent in an impact, shows corrosion at the bearing journals, or produces movement at the steering wheel should be replaced rather than run on.

Buying Advice

Confirm the column length fitted to your chassis before ordering — check your chassis documentation or measure the existing column from hub to hub. The 470mm and 490mm are both stocked; if you need a non-standard length such as 520mm or 540mm for a taller driver, check the available OTK extended column options. The steering column should always be replaced with the bearings and circlip checked at the same time — see the OTK Steering Column Bearing 10mm and associated hardware.
