TRX-2668 Spring Retainers: The Detail That Keeps the Suspension in Place

In the world of RC modelling, small suspension components make the difference between predictable behaviour and irregular geometry that affects track or off-road performance. The spring retainers upper & lower with reference TRX-2668 are the spring retainers —upper and lower— designed for Traxxas models that utilise this type of suspension system.

Function and Performance

The function of these retainers is to keep the suspension springs properly seated at both ends of the shock absorber, preventing lateral movement that could compromise the suspension response. A misaligned spring can result in asymmetric behaviour, uneven wear, or, directly, the loss of the spring during use.

The pack includes 2 units (upper retainer and lower retainer), allowing for the replenishment or replacement of the complete set of a shock absorber in a single purchase.

Assembly and Preparation

The installation is straightforward: the retainers are placed at the ends of the spring before assembling the shock absorber. It is advisable to check their condition periodically, especially in models that are used intensively or on abrasive surfaces, as the plastic may suffer deformation or breakage from impact.

• Check that the retainer sits correctly on the shock absorber seat before closing.
• Do not force the fit: if there is resistance, check that the spring is properly aligned.
• In case of replacement, take the opportunity to also inspect the condition of the spring and the body of the shock absorber.

Compatibility

This spare part corresponds to the official Traxxas reference TRX-2668. To confirm the exact compatibility with your specific model, we recommend consulting your vehicle's parts manual or the official Traxxas catalogue, as this reference may apply to several models in the range.

Frequently Asked Questions

How many units are included in the TRX-2668 pack?

The pack includes 2 units: one upper retainer and one lower retainer, corresponding to a complete shock absorber.

What exactly is the purpose of a spring retainer?

It keeps the spring centred and correctly positioned at both ends of the shock absorber, preventing movements that affect the suspension response or cause loss of the spring during use.

How often should I check these retainers?

It depends on usage, but in general, it is advisable to inspect them each time the shock absorber is disassembled for maintenance, or in the event of any irregular behaviour of the suspension.

Can I use retainers from other brands as a substitute?

It is most advisable to always use the original Traxxas reference TRX-2668 to ensure the correct fit and avoid dimensional compatibility issues.

The Traxxas TRX-2668 spring retainers upper and lower (pack of 2) are genuine replacement parts designed to keep suspension springs correctly seated on compatible Traxxas RC models. Essential for maintaining consistent suspension geometry and reliable performance, these retainers are a must-have spare for any Traxxas enthusiast looking to keep their vehicle in top condition.
