T4 V-2 Shock Spring

SRC T4 V-2 Shock Springs: Millimetric Precision for Your Slot Suspension

When it comes to fine tuning, every tenth of a millimetre matters. The SRC T4 V-2 shock springs (ref. SRCRM0819) are the specific replacement for the shocks of slot cars that incorporate this suspension system, ensuring that the geometry of the body and the on-track behaviour are maintained exactly as the designers at SRC intended.

Technical Features

Function and Performance

The spring is the heart of any damping system. Its stiffness and geometry determine how the suspension reacts to the undulations and changes in gradient of the track, directly influencing the guide's contact with the rail and the overall stability of the car. A fatigued or deformed spring results in erratic behaviour, loss of grip, and an increased risk of derailment in fast corners.

Having original SRC replacement springs allows you to restore the factory response of the T4 V-2 shock without needing to adjust other chassis parameters, saving time on the workbench and ensuring reproducibility of the setup between sessions.

Compatibility and Installation

These springs are specifically designed for the SRC T4 V-2 shock. Before proceeding with the replacement, ensure that the dimensions (length 5.8 mm, Ø ext. 2.8 mm, Ø int. 2.4 mm) match exactly with the original springs of your shock assembly. A correct installation does not require special tools, although fine-tipped pliers facilitate assembly without deforming the coil.

Common Mistakes

• Mixing springs of different stiffness on the same axle: this creates asymmetrical behaviour and complicates the diagnosis of handling issues.
• Forcing the spring beyond its nominal travel during installation: this can cause permanent deformation that nullifies its damping function.
• Not checking the condition of the seat before installing the new spring: if the seat is damaged, the spring will work at an angle and wear out prematurely.

Frequently Asked Questions

How many springs are included in this pack?

The SRCRM0819 pack includes 4 T4 V-2 shock springs.

Are they interchangeable with springs from other brands that have the same measurements?

In theory, any spring with the same length (5.8 mm), outer diameter (2.8 mm), and inner diameter (2.4 mm) could work, but the stiffness (spring constant) may vary between manufacturers. To ensure factory behaviour, we recommend always using the original SRC replacement.

How often should I check or change these springs?

There is no fixed interval: it depends on the intensity of use and whether the car has suffered impacts or rollovers. A good practice is to visually inspect them at each maintenance session, checking that they retain their free length and do not have open or deformed coils.

Do I need special tools for the replacement?

No special tools are required. Fine-tipped pliers or a watchmaker's screwdriver facilitate the removal and insertion of the spring without damaging the shock assembly.
