Red extra hard short box sidewinder chassis

Precision and rigidity for your sidewinder setup: the NSR cradle in extra-hard red compound

When preparing a slot car with a sidewinder configuration —motor positioned parallel to the rear axle— the cradle that holds the motor is one of the components that most influences the consistency of the transmission. NSR knows this well, which is why it offers these cradles in different material hardnesses so that each driver can find the balance they seek.

Main features

• Short can format: designed for NSR short can motors, it ensures a precise fit without unnecessary play.
• Extra-hard compound (red): the stiffest material in the NSR range. It minimizes cradle flex under load, maintaining a constant distance between pinion and crown gear throughout the race.
• Sidewinder configuration: optimised for mounting with the motor in a transverse position relative to the rear axle.
• NSR reference: NSR1249b.

What does the extra hardness in the cradle provide?

The material of the cradle directly affects how power is transmitted from the motor to the crown gear. A soft cradle absorbs vibrations but can generate micro-movements that disrupt the pinion engagement. The extra-hard version in red virtually eliminates that variable: the motor is anchored with maximum rigidity, resulting in a more direct transmission and a more predictable response during braking and acceleration. It is the usual choice on technical tracks with many rhythm changes, where consistency lap after lap makes the difference.

Compatibility and mounting

This cradle is designed for NSR chassis that allow sidewinder mounting with a short can motor. Before purchasing, check that your NSR chassis accepts this format and that the motor you are using corresponds to the short can. NSR offers a wide range of cradles in different hardnesses and lengths, so it is advisable to consult your chassis diagram to confirm the correct reference.

Usage recommendations

• Check the pinion-crown gear mesh after mounting: the extra rigidity of the material does not forgive a careless adjustment.
• If you notice that the car feels twitchy or not sliding well in slow corners, try comparing with a lower hardness before adjusting other parameters.
• Use it along with the motor mounting screws recommended by NSR to ensure that the cradle operates under optimal conditions.

Frequently asked questions

What is the difference between the short can cradle and the long can cradle?

The length of the can refers to the size of the motor. NSR short can motors are more compact than long can motors. Using the incorrect cradle prevents a proper motor fit and can damage both the cradle and the motor itself.

What is the purpose of having different hardnesses in the cradles?

Each hardness offers different behaviour in terms of vibration transmission and rigidity. The soft compound absorbs more impacts and can enhance traction on rough tracks; the extra-hard (red) maximises rigidity and consistency in transmission, being preferred in competition where time repeatability is a priority.

Is this cradle compatible with chassis from other brands?

This cradle is specifically designed for NSR chassis. Although some chassis from other brands may have similar dimensions, NSR does not guarantee compatibility outside its own range. We recommend verifying this before mounting.

Can I use this cradle in an inline or anglewinder configuration?

No. This cradle is designed exclusively for sidewinder mounting (motor parallel to the rear axle). For inline or anglewinder configurations, NSR offers specific cradles for each type of mounting.

Which NSR short can motor is the most common for this cradle?

NSR manufactures several short can motors compatible with this type of cradle. The choice of motor depends on the regulations of your championship and the type of track. Consult the technical sheet of your NSR chassis to confirm which motors it accepts.

The NSR short-can sidewinder motor pod in extra-hard compound (red) is a precision slot car part designed for sidewinder motor mounting in NSR short-can motor configurations. Ideal for club racing and competition, this rigid pod minimizes flex and ensures consistent pinion-to-crown mesh lap after lap. A top choice for NSR slot car tuning and setup among serious slot car racers and hobbyists.
