34z 16.8mm Crown Anglewinder

Crown Anglewinder NSR6534: 34 teeth and 16.8 mm to fine-tune your transmission

When the motor mounting is anglewinder —that is, with the motor positioned at an angle to the rear axle— the crown gear is a critical component. A correct tooth count and well-calculated diameter make the difference between a car that accelerates cleanly from the start and one that slips or suffers traction loss in fast corners. The NSR6534 meets that need exactly: 34 teeth, 16.8 mm in diameter, and manufactured by NSR.

Technical specifications

• Reference: NSR6534
• Number of teeth: 34z
• Diameter: 16.8 mm
• Mounting type: Anglewinder (motor at an angle to the rear axle)
• Recommended pinions: NSR71XX series, with 7.5 mm diameter
• Application: NSR cars with anglewinder configuration

Function and performance

The crown transmits the motor's force to the rear axle, and its ratio with the pinion determines the acceleration response and top speed. A 34-tooth crown offers a relatively long gear ratio when combined with small pinions, favouring higher top speed at the expense of some acceleration. If you seek more acceleration, simply increase the number of teeth on the pinion; if you want more top speed on fast circuits, decrease it. With the NSR71XX pinions of 7.5 mm, you have a solid and tested base from the brand itself.

Compatibility and installation

This crown is specifically designed for NSR cars with anglewinder motors. Before installation, it is advisable to check that the chassis accommodates this type of setup and that the wheelbase is correct for a clean mesh. NSR manufactures its crowns with very tight tolerances, making installation easy without the need for additional adjustments on most of the brand's chassis.

Common mistakes when choosing a crown

• Confusing anglewinder crowns with sidewinder or inline mounting crowns: they are not interchangeable, as the tooth attack angle varies.
• Pairing the crown with pinions of a different diameter or module than recommended, causing play, noise, and premature wear.
• Installing without checking the lateral alignment of the gear, generating vibrations and loss of efficiency.

Ideal for…

Enthusiasts and club competitors who prepare or tune NSR cars with anglewinder configuration and want to work with reference components from the brand itself. It is also useful as a direct replacement when the original crown shows wear on the tooth flanks.

Frequently asked questions

Can I use this crown on a sidewinder motor car?

No. Anglewinder crowns have a specific tooth profile for the attack angle of that type of mounting. Using them on a sidewinder would result in poor meshing and accelerated wear.

What pinion is recommended for this crown?

NSR recommends pairing the NSR6534 with pinions from the NSR71XX series, which have a diameter of 7.5 mm. The choice of the number of teeth on the pinion will depend on whether you prioritise acceleration or top speed on your circuit.

Which NSR cars is it compatible with?

It is designed for NSR cars with anglewinder configuration. We recommend checking the manual or technical sheet of your specific model to confirm compatibility before purchase.

When should the crown be replaced?

When you observe visible wear on the tooth flanks, excessive play in the meshing, abnormal noise during operation, or loss of traction without any apparent cause. Periodic inspection extends the life of the transmission set.

Is it necessary to use lubricant on the gear?

A minimal amount of specific slot gear lubricant improves durability and reduces noise. Apply sparingly: excess attracts dirt and can contaminate the tyres.
