Where additional stability may be required the BCS Wheel Spacers can be fitted to push the wheels out either side. They simply bolt to the wheel hubs to extend the width by 6cm (2½") on either wheel.
They are supplied as a pair, and up to 2 pairs can be fitted to each wheel. The wheel spacers can also be used to twin together two pneumatic wheels for greater traction and for providing torque between the wheels.
