A steering wheel is only as good as the way it fits your car. That’s where the boss kit comes in.
While it’s often hidden from view once fitted, the boss kit is one of the most important components in any steering wheel installation. It provides the secure, accurate connection between your Moto-Lita steering wheel and your car’s steering column, ensuring the wheel sits correctly, functions properly and feels right every time you drive.
This guide explains what a boss kit does, why it matters, and how to choose the correct one.
What Is a Steering Wheel Boss Kit?
A boss kit is the adaptor that allows a steering wheel to be mounted onto a specific vehicle’s steering column.
Every car has a different steering column design, with variations in:
- Spline count
- Shaft diameter
- Column length
- Taper
- Indicator cancellation mechanism
-
Finish - polished / painted
The boss kit is engineered to match these details precisely, ensuring the steering wheel fits safely and correctly.
Without the correct boss kit, a steering wheel cannot be fitted properly.
Why the Correct Boss Kit Matters
Choosing the right boss kit is not just about fit. It affects how the car drives and operates.
A correctly specified Moto-Lita boss kit ensures:
- The steering wheel is securely mounted
- The wheel sits at the correct depth and alignment
- The horn functions as intended
-
Indicator self-cancellation works correctly (where applicable)
Using the wrong boss can result in poor alignment, compromised safety, or loss of functionality.
Moto-Lita Boss Kits: Built for Accuracy
Moto-Lita boss kits are engineered with the same attention to detail as our steering wheels.
Many of our bosses are:
- Machined in the UK from solid billet aluminium
- Hand-broached to ensure a precise spline fit
-
Designed specifically for individual vehicle applications
This level of precision ensures a snug, reliable fit on the steering column, eliminating play and ensuring confidence behind the wheel.
Fixed vs Adjustable Boss Kits
Depending on your car and seating position, you may have options when it comes to boss style.
- Fixed boss kits position the wheel in a set location, ideal for many standard installations.
-
Adjustable boss kits allow for fine-tuning of wheel position, which can be helpful in cars with limited cabin space or modified seating.
Compatibility with Moto-Lita Steering Wheels
Moto-Lita steering wheels use a standard fixing pattern, allowing them to work seamlessly with our boss kits.
Boss kits are designed to:
- Accept Moto-Lita wheels directly
- Accommodate horn buttons and fixings
-
Sit neatly within the wheel centre
