RT4 Bridge Spring SL

The spring bridge that keeps the RT4 chassis at its optimum

The RT4 Spring Bridge SL (CRT-226) from Cumbre Racing Technologies is a specific preparation replacement for Slot.it compatible RT4 chassis. Designed to replace the original spring bridge with guarantees of fit and function, this component is part of the precision parts range that Cumbre Racing Technologies offers to the most demanding enthusiasts.

Function and performance

The spring bridge is a key element in the chassis geometry: it retains and positions the suspension spring correctly, directly influencing the car's response to changes in elevation and track irregularities. A damaged or worn bridge can cause erratic behaviour, loss of traction, and variations in the guide's contact with the track.

Having replacement units like the CRT-226 allows you to keep the chassis in stock conditions or adapt it during the tuning process, ensuring consistent performance race after race.

Compatibility

This bridge is designed for RT4 chassis with the Sport rail system, used on tracks from brands like Scaleauto or Slot.it. Always check that the bridge is the correct one for your version of the RT4 chassis and that the associated spring is compatible with the CRT-226 reference before installation.

Pack contents

Each pack includes 8 units of the RT4 Spring Bridge SL, making it practical for preparation workshops as well as for clubs or drivers who maintain several cars in competition simultaneously.

Assembly and preparation

• Carefully remove the spring and the original bridge without damaging the chassis base.
• Place the new bridge ensuring it is correctly seated in its housings.
• Reposition the spring and check the freedom of movement of the assembly before closing the chassis.
• Check the track behaviour with a reconnaissance lap before definitively adjusting the spring hardness.

Common errors

• Mixing bridge references: not all bridges for RT4 chassis are interchangeable. Always confirm that the bridge corresponds to the SL version of your chassis.
• Reusing deformed bridges: a plastic bridge subjected to heat or impacts may have lost its original geometry. When in doubt, replace it.
• Neglecting the replacement: leaving the chassis operational with a deteriorated bridge directly affects lap time consistency.
