High Precision Narrow Pinion for Touring Cars

Hobbyists seeking a weight saving will find the XRAY 305918 Narrow Pinion Gear a practical upgrade. Fabricated from aircraft duraluminium, it is 1.5mm slimmer and about 25% lighter than many stock pinions, while keeping the required strength for track use.

Machined Accuracy and Protective Finish

Each XRAY pinion is machined on precision gear equipment to ensure tight tolerances and excellent concentricity. Teeth are chamfered and then treated with a hardcoat to extend service life. This attention to detail improves mesh quality and cuts down on drivetrain noise, particularly when matched with XRAY spur gears.

Fits T4 Series Chassis and Daily Use

The XRAY 305918 Narrow Pinion Gear fits T4 Series models, including the T4 2017 Specs. It suits both performance-oriented builds and routine replacements, delivering reliable gear engagement out of the box.
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.

Is the XRAY 305918 compatible with sealed gearboxes?

Yes, it can be used in sealed setups as long as shaft clearance and pitch match. Ensure proper ventilation and check mesh periodically.

How significant is the weight difference on handling?

Reducing rotating mass can improve acceleration and transient response. The practical effect depends on the rest of your setup and track conditions.

Should I pair this pinion with XRAY spur gears only?

While optimised for XRAY spur gears, it works with any correctly specified spur. Matching pitch and ensuring correct mesh are the key factors.
