The 3DSRP SRP-SB01 Leaf Spring: Precision Suspension for 1/32 Chassis Without Compromises

When building or tuning a 1/32 competition chassis, every gram and every millimetre of travel counts. The 3DSRP SRP-SB01 suspension leaf spring offers a direct and effective solution: replacing conventional springs with a leaf spring system that works just like the leaf springs of real vehicles, with the advantage of fully controlled adjustment via the screws of the suspension itself.

Function and Performance

A suspension leaf spring works by flexing the piece: the tighter the screws are, the greater the resistance it offers; loosening them allows the suspension to gain softness and travel. This progressive and linear behaviour enables the tuner to find the exact point of stiffness without the need to change springs or calculate spring constants.

• Leaf spring system: continuous adjustment via screw, without spring changes.
• Designed for chassis that operate without springs.
• Compatible with Slot.it-type motor mounts.
• Weight: 0.2 g — minimal impact on chassis balance.
• 1 unit per reference.

Compatibility and Installation

The SRP-SB01 is designed for 1/32 chassis with Slot.it-type motor mounts. Before installing it, it is advisable to check that the receiving chassis does not incorporate its own springs that may interfere with the flexing of the leaf spring. The adjustment is made directly on the existing suspension screws in the chassis: no special tools or additional parts are needed for the initial setup.

Installation and Preparation

1. Remove any existing springs from the suspension if present.
2. Place the leaf spring in its housing according to the geometry of the chassis.
3. Gradually adjust the suspension screws until the desired working point is found.
4. Check the vertical travel of the assembly before mounting the chassis on the track.

Common Mistakes

• Leaving the original springs in place: the leaf spring is designed to replace them, not to work in parallel with them.
• Over-tightening from the start: it is advisable to begin with moderate tightening and adjust in short sessions on the track.
• Not checking the compatibility of the motor mount: this leaf spring is specific for Slot.it-type mounts; other types of chassis may require adaptations.

Frequently Asked Questions

How many units does the SRP-SB01 reference include?

The reference includes 1 unit of suspension leaf spring.

Do I need to keep the springs from my chassis when installing this leaf spring?

No. The SRP-SB01 leaf spring is designed to work without springs. Removing them is part of the correct installation for the leaf spring to function as the sole elastic element of the suspension.

How is the stiffness of the suspension adjusted?

Tightening the suspension screws increases stiffness; loosening them achieves a softer behaviour. No parts need to be replaced to change the configuration.

Is it compatible with any 1/32 chassis?

Compatibility is specified for chassis with Slot.it-type motor mounts. For other types of chassis, we recommend checking before installation.

How much does the leaf spring weigh?

It weighs 0.2 g, so its impact on the overall balance of the chassis is practically negligible.

The 3DSRP SRP-SB01 is a 1/32 slot car suspension leaf spring designed for use without coil springs, compatible with Slot.it-type motor mounts. Regulation is achieved by tightening or loosening the suspension screws, providing precise and progressive stiffness control. Weighing just 0.2 g, it is an ideal upgrade for competitive 1/32 chassis builders looking for consistent and adjustable suspension behaviour on the slot car track.
