A go-kart steering column is the shaft that connects the steering wheel to the steering linkage. It turns when you turn the wheel, and a short arm at its lower end, often called the pitman arm or steering arm, pushes and pulls the tie rods that steer the front wheels. Replacing or upgrading one comes down to matching the shaft diameter, length, hub style, and supports to your kart. Complete columns typically cost $25 to $100, and a bent column should always be replaced, not straightened. This guide explains column types, how to measure for a replacement, how to set the angle and supports, and how to install one safely.

How a Go-Kart Steering Column Works
Most go-karts use direct steering. The column is a straight shaft, and the arm at its base moves the tie rods side to side as you turn the wheel. There is no gearbox in between, so steering feel is immediate and any looseness in the column shows up instantly in your hands.
Some larger yard and off-road karts use rack-and-pinion steering instead. In that case, the column turns a pinion gear that moves a rack, and the tie rods attach to the rack ends. If your kart has a rack, the column’s lower end connects to the pinion, often through a universal joint. Our go-kart rack and pinion steering guide covers that setup, and the go-kart steering overview explains how the whole system fits together.
Parts of a Go-Kart Steering Column
- Shaft: solid steel bar on many yard karts, hollow tube on many racing karts.
- Steering wheel hub: attaches the wheel to the top of the shaft by a keyway, a bolted flange, or a weld.
- Upper support: a bushing, bearing, or clamp near the wheel that holds the shaft in place.
- Lower support: a bearing or bushing near the bottom, close to the steering arm.
- Steering arm (pitman arm): the lever at the bottom where the tie rods attach.
- Collars: keep the shaft from sliding up or down in its supports.

Types of Go-Kart Steering Columns
Welded columns. The hub and steering arm are welded to the shaft. Cheap and solid with no slop, but nothing can be adjusted, and damage to any part means replacing the whole assembly. Common on kids’ karts and simple yard karts.
Keyed columns. The steering wheel hub slides onto the shaft and locks with a key in a keyway, secured by a bolt or set screw. You can change wheels, reposition the hub, or replace parts individually. This is the usual choice for DIY and adult yard karts.
Racing columns. Sprint karts commonly use a hollow steel column, often around 20 mm in diameter, with a bolt-on hub at the top that accepts standard kart steering wheels. Supports and hub patterns vary by chassis, so check with the chassis maker for replacements.
Columns with universal joints. Used where the wheel and the steering box or rack are not in a straight line. They allow more flexible packaging but add parts that can wear and develop play.
Quick-release setups. A coupler between the hub and the wheel lets you pull the wheel off to get in and out. Useful in tight cockpits and on shared karts. See our go-kart quick release steering wheel guide for how they work.
Steering Column Options Compared
| Type | Hub attachment | Adjustability | Typical cost | Best for |
|---|---|---|---|---|
| Welded column | Welded | None | $20–$45 | Kids and simple yard karts |
| Keyed column | Key and set screw or bolt | Wheel and hub swaps | $25–$70 | DIY and adult yard karts |
| Racing column | Bolt-on hub | Hub, wheel, and height options | $40–$100 | Sprint and race karts |
| Column with U-joint | Varies | Flexible angles | $40–$100 | Rack-and-pinion and offset layouts |
Costs are typical USD ranges for the column assembly. Steering wheels, quick-release couplers, and supports may be extra.
How to Measure for a Replacement Steering Column
Measure the old column before you order, or measure the frame if it is a new build.
- Diameter: use calipers on an unworn section. Small yard karts commonly use 5/8-inch or 3/4-inch shafts; racing karts commonly use metric tube.
- Length: measure overall length and the distance from the top of the shaft to the steering arm.
- Hub style: note the key size, the bolt pattern of a flanged hub, or whether it is welded.
- Steering arm: measure its length, the hole size for the tie rod ends, and its angle relative to the hub.
- Supports: note the bushing or bearing sizes and the collar positions.
Use the same steering arm length unless you are deliberately changing the steering ratio. A longer arm moves the tie rods further for each degree of wheel rotation, making steering quicker but heavier; a shorter arm does the opposite.
Supports and Column Angle
A column needs at least two support points, one near the top and one near the bottom. Nylon or bronze bushings are cheap and work, but they wear oval over time, especially in dusty conditions, and let the column move. Sealed flange bearings cost a little more and generally stay tight much longer. Long columns may need a middle support to stop them from flexing.
The column angle sets where the wheel sits relative to the driver. Aim for a position where the driver can hold the wheel with elbows slightly bent and shoulders against the seat, with enough clearance above the legs to turn lock to lock. The exact angle depends on the seat position and driver size, so mock it up with the driver seated before welding any support tabs. Our go-kart steering kit guide covers complete assemblies if you are building from scratch.
How to Replace a Bent Go-Kart Steering Column
A bent column shows up as an off-center wheel, a wheel that wobbles as it turns, steering that binds at one point, or a kart that pulls after a crash or curb strike. Do not straighten a bent column. Bending it back can leave a weakened spot that may crack later.
- Point the front wheels straight ahead and note the steering wheel position.
- Remove the steering wheel and hub.
- Disconnect the tie rod ends from the steering arm.
- Loosen the support collars and remove the upper support if needed, then slide the column out.
- Inspect the supports, tie rod ends, and spindles. A hit hard enough to bend the column may have damaged them too.
- Install the new column, collars, and supports. The shaft should rotate freely with no binding.
- Reconnect the tie rods using new locknuts, then set the front wheels straight with the wheel centered.
- Check toe and adjust the tie rods if needed. Our go-kart steering linkage guide explains the adjustment.
Safety Checks
The steering column is a part that must never fail, so check it carefully after installation and regularly afterward.
Shake test. Grab the wheel and push and pull in every direction. Any clicking or movement means a loose hub, a worn support, or a missing key.
Lock to lock. Turn the wheel fully left and right. Steering should be smooth with no tight spots, and nothing should touch the frame, bodywork, or the driver’s legs.
Fasteners. All steering bolts should use locknuts or be secured with cotter pins or safety wire, as the parts maker recommends. A steering arm that comes loose or spins on the shaft means total loss of steering.
Welds. Inspect welds on the steering arm and support tabs for cracks, especially after any impact.
Steering Column Maintenance
Add the column to your regular pre-ride checks. Do the shake test, confirm the hub bolt and set screws are tight, and look at the collars to make sure the shaft cannot slide in its supports. Every few sessions, remove the wheel and inspect the keyway and hub for wear or elongation.
Keep bushings clean; dirt packed into a bushing speeds up wear. Replace bushings as soon as you can feel play rather than waiting for them to get worse. On karts stored outdoors, watch for rust where the shaft passes through its supports, since a pitted shaft wears new bushings quickly.
