The 3Racing RE-043A/B4 set comes as two pairs (four pcs) finished in blue and is aimed at hobbyists running 40 Series wheel sizes. It serves as a replacement assembly or a styling and handling option on short-course and monster truck chassis that accept wide offset wheels.
Units are supplied pre-mounted and ready for installation on compatible wheel hexes; no extra tools or adapters are provided. Confirm hub spacing and hex compatibility with your model before attempting to fit the wheels.
Using a wide offset shifts the tyre footprint outward which can improve cornering grip on loose surfaces but also changes roll dynamics. We recommend pairing these wheels with revised shock and tyre pressure settings to keep handling predictable and to protect drivetrain parts.
These wheels are a practical choice for increasing track width or achieving a specific look on 40 Series-equipped trucks; always verify clearance to steering and suspension components first.
