T4 V-3 Shock Absorber Spring

SRC T4 V-3 Shock Absorber Springs: The Adjustment That Makes a Difference on Track

When your slot car's suspension is not responding as it should, the shock absorber springs are the first elements to check. This pack of 4 T4 V-3 shock absorber springs from SRC (reference SRCRM0820) offers the exact original replacement to restore the vehicle's original behaviour or to adjust the suspension stiffness according to your driving preferences.

Technical Specifications

• Pack contents: 4 x T4 V-3 Shock Absorber Spring
• Length: 6.0 mm
• Outer diameter: 2.8 mm
• Inner diameter: 2.4 mm
• Reference: SRCRM0820
• Brand: SRC

Function and Performance

The shock absorber springs work in conjunction with the car's suspension system to absorb track irregularities and maintain contact between the guide and the track at all times. A damaged spring —deformed, fatigued, or with incorrect tension— can result in loss of grip, derailments in fast corners, or erratic behaviour that is difficult to diagnose.

Having the exact measurements of the original spring (length 6.0 mm, Ø ext. 2.8 mm, Ø int. 2.4 mm) ensures that the suspension geometry is not altered and that the car regains the factory feel.

Installation and Preparation

The replacement process is straightforward: remove the worn spring from the shock absorber housing, clean the seat of any dirt or grease buildup, and install the new spring ensuring it is correctly centred. Given the small scale of the parts, it is recommended to use fine-tipped tweezers to facilitate handling without damaging the spring or the housing.

The pack includes 4 units, allowing you to renew the springs of several suspension points of the vehicle in a single intervention or to keep spare units for future maintenance.

Common Mistakes

• Mixing springs of different lengths or diameters: alters the behaviour of the suspension and can cause unwanted rubbing.
• Installing the spring inverted: although in most designs it has no functional consequences, it is advisable to respect the original orientation.
• Not checking the condition of the housing: if the spring seat is deformed, the replacement will not solve the problem at its root.

Frequently Asked Questions

Which SRC models are these springs compatible with?

They correspond to reference SRCRM0820 from the SRC spare parts catalogue for the T4 V-3 shock absorber system. We recommend consulting your model's manual or contacting us to confirm the exact compatibility with your vehicle.

How many springs does the pack contain?

The pack includes 4 T4 V-3 shock absorber springs.

How often should shock absorber springs be replaced?

It depends on usage and track conditions. A periodic visual inspection —looking for deformations, loss of tension, or corrosion— is sufficient to determine when it is time to replace them.

Can I use these springs to adjust the suspension stiffness?

These springs are the original factory replacement. To modify the suspension stiffness, springs with different spring constants are required; in that case, consult us for the available options in the SRC catalogue.

Can they be installed without special tools?

No special tools are needed, although fine-tipped tweezers greatly facilitate the work given the small size of the parts.

The SRC SRCRM0820 is a set of 4 T4 V-3 shock absorber springs designed as original replacement parts for SRC slot cars. With a length of 6.0 mm, outer diameter of 2.8 mm and inner diameter of 2.4 mm, these springs ensure correct suspension geometry and consistent guide contact on the track. An essential spare part for club racers and hobbyists looking to maintain or restore their SRC slot car's handling performance.
