Spring Block T4 V-1 x4

Four SRC Block T4 V-1 Springs to Keep Your Guide in Place

The Block T4 V-1 spring is a small component with a critical function in any slot car: to keep the guide block in the correct working position and to dampen the impacts that the guide receives during driving. With this pack of 4 units (ref. SRCRM0815), you have enough spares to prepare several cars or to always have on hand when it's time for maintenance.

Function and Performance

The block spring acts directly on the guide assembly, ensuring that it returns to its central position after each corner and absorbs the irregularities of the track correctly. A worn or tension-lost spring results in a guide that "wobbles," does not recover well, and increases the risk of derailment in fast chicanes or compromised corner entries.

The V-1 model from SRC is designed for T4-type blocks, common in the brand's cars. Preventive replacement is part of any serious preparation, especially when the car has accumulated many competitive laps.

Installation and Preparation

The change is straightforward: simply remove the guide, extract the block, and replace the spring with a new one. No special tools are required. It is advisable to also check the condition of the block and the guide itself to ensure that the assembly is working in perfect condition.

Compatibility

This spring is specifically designed for SRC T4-type guide blocks. Before applying it to cars from other brands, check that the block geometry is compatible.

Frequently Asked Questions

How often should the guide block spring be replaced?

It depends on usage. In competition cars with many laps, it is advisable to check it during each serious setup. If you notice that the guide does not return well to the centre or that the car slides earlier than usual in fast corners, it is a clear sign that the spring has lost tension.

Does this pack also include the guide or the block?

No. The SRCRM0815 pack contains only the 4 Block T4 V-1 springs. The guide and guide block are sold separately.

Are they valid for universal and Sport track?

The spring itself is compatible with both systems as long as the SRC T4 guide block is present in the car. The width of the track does not affect the function of the spring.

Does it make sense to change only the spring without checking the rest of the guide assembly?

It is possible, but the most efficient approach is to take advantage of the disassembly to also inspect the block, the guide, and the braids. A new spring in a worn assembly will not yield the best results.

The SRC Block T4 V-1 spring set (ref. SRCRM0815) is a pack of 4 replacement springs designed for T4-type guide blocks in SRC slot cars. Essential for competitive preparation and regular maintenance, these springs ensure consistent guide return and stable handling on both universal and Sport track systems.
