Rear spring Bench L4.5 x 4E x4

Four rear pod springs for Bolt system to fine-tune your slot car setup

The Rear Pod Spring L4.5 x 4E x4 (ref. SRCRM0822) is a pack of four springs specifically designed for pods with the Bolt system. A small but decisive component: the rear pod spring is responsible for maintaining the correct pressure and seating of the pod on the chassis, directly influencing the stability of the rear end and the car's behaviour in corners.

Technical specifications

• Pack contents: 4 rear pod springs
• System: Bolt system
• Spring length: 4.5 mm
• Number of coils: 4
• Outer diameter: 4.55 mm
• Wire diameter: 0.20 mm

Compatibility

These springs are valid for all models that feature the Bolt system on their rear pod. Compatible categories include:

• LMP1 «Toyota»
• IMSA
• GT
• Other categories using the Bolt system on the rear pod

If you are unsure whether your model uses the Bolt system, check the rear pod: this system is characterised by a specific screw-mounted assembly that distinguishes these cars from the rest of the catalogue.

Function and performance

The rear pod spring has a seemingly simple function but a significant impact on the car's dynamic behaviour. An incorrect stiffness or length can cause the pod to operate with too much rigidity—reducing grip in corners—or with excessive play, generating instability during braking and direction changes. With this pack, you have four units to replace worn springs or to experiment with the setup based on the track and driving style.

Installation and preparation

Changing the rear pod spring is a common preparation operation in any competitor's workshop. We recommend checking the condition of the springs periodically, especially after intense sessions or if erratic behaviour is detected in the rear end. When replacing them, ensure that the pod seating is clean and free of dirt before installing the new spring, to guarantee it works correctly from the first moment.

Frequently asked questions

What is the difference between springs of different lengths for the pod?

A greater length generally implies a different preload on the pod, which affects the pressure with which the rear end operates. Longer springs can provide more softness; shorter ones, more firmness. The choice depends on the track and the overall setup of the car.

Why are 4 units included in the pack?

Having spare units on hand is essential in competition. Springs are wear parts that can fatigue or deform with use, and having several units allows for quick adjustments between heats without interrupting the session.

How do I know if my car uses the Bolt system?

The Bolt system is a screw-mounted pod assembly system. Check the rear pod of your model and consult the manufacturer's manual or technical sheet. The LMP1 Toyota, IMSA, and GT categories in the catalogue are the most common references that incorporate it.

Can I use these springs on cars from other brands?

As long as the car in question features the Bolt system with the same pod dimensions, it could be compatible. However, we recommend verifying the measurements accurately before proceeding with the installation.
