Reduce Drivetrain Drag with XRAY Belt

The XRAY 305438 drive belt is designed to lower drivetrain drag on the X4F 2025 series, improving efficiency in power transfer. Its minimal, elastic profile supports smoother transmissions and can help decrease battery voltage draw during running.

Careful Grinding for Reduced Thickness

Each belt is hand-ground to reach a very low thickness while keeping adequate strength. This process yields a flexible belt that seats accurately on pulleys, cutting friction inside the gearbox. Maintain clean ball-bearings to get the most from this belt's low-drag design.

Setup and Maintenance Recommendations

Before fitting the XRAY 305438 clean the gearbox and check pulley alignment. Regular bearing cleaning and routine checks of belt run-in will help sustain minimal drag and consistent on-track performance.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What surfaces are suitable when running this belt?

The belt works across typical on-road and smooth off-road surfaces used for X4F setups. Avoid excessive dust or mud which speeds wear and increases drivetrain drag.

Can I upgrade bearings to improve results?

Upgrading to high-quality, sealed ball-bearings can reduce friction and protect against contamination, helping the belt perform closer to its design intent.

How should I store spare belts?

Store belts flat in a cool, dry place away from direct sunlight to avoid premature hardening or deformation. Keep them away from solvents and oils.

Is belt alignment critical for performance?

Yes, misaligned pulleys increase wear and drag. Check pulley faces and shaft positioning when fitting to ensure even seating across the belt.

What signs indicate the belt needs replacing?

Replace the belt if you see cracks, fraying, glazing, or if run times and drivetrain smoothness noticeably decline despite clean bearings.
