Technical Performance
The Fastrax spring set represents quality engineering focused on delivering reliable suspension components for demanding RC applications. Each spring in the set has been manufactured to precise specifications to ensure consistent performance and durability. The 75mm length is a standard specification across many 1/10 scale RC platforms, making these springs a practical choice for owners of popular models. The varying stiffness ratings allow for meaningful suspension tuning without requiring expensive specialist equipment or extensive mechanical knowledge. By selecting the appropriate spring stiffness from soft to hard, you can adjust how your RC car's suspension compresses and extends, directly influencing traction, stability and driving feel. Softer springs provide more compliance and comfort over rough terrain, whilst harder springs offer increased support and precision for racing. The colour-coding system ensures you can quickly identify and swap springs between multiple vehicles or during testing sessions, making these springs practical for serious hobbyists running multiple 1/10 scale RC cars. Build quality is consistent with Fastrax's reputation for reliable spare parts, and these springs will withstand the rigours of regular bashing and competitive use.

Frequently Asked Questions
- What is the difference between soft, medium and hard springs in an RC car suspension? — Soft springs compress more easily and provide a more comfortable, compliant ride over bumpy terrain, but offer less precise handling under aggressive driving. Medium springs offer a balanced compromise suitable for general driving. Hard springs resist compression, providing firmer, more predictable handling for racing and technical driving, but may feel harsh over very rough ground. The choice depends on your driving style, terrain type and the specific handling characteristics you prefer.
- Will these 75mm springs fit my 1/10 scale RC car? — These springs are designed for 1/10 scale RC cars using 75mm shock bodies, which is a standard specification across many popular models. However, you should check your vehicle's shock specifications before ordering to ensure compatibility, as some 1/10 scale cars may use different shock lengths such as 70mm or 80mm.
- Are these springs suitable for beginners? — Yes, absolutely. Beginners will benefit from having multiple spring stiffness options available, allowing them to discover which suspension setup they prefer without expensive trial and error. Starting with the medium spring is a sensible approach, then switching to soft or hard springs based on your experience and the terrain you're driving on.
- How often should I replace my RC car's springs? — Springs are durable components and don't typically wear out quickly with normal use. However, if you notice reduced suspension performance, inconsistent ride height or visible damage to the springs, replacement is advisable. These Fastrax springs provide spare options for both maintenance and performance tuning.
- Can I use these springs with different 1/10 scale RC car brands? — Provided your RC car uses 75mm shock bodies, these springs should be compatible with most 1/10 scale vehicles regardless of brand, including popular platforms from Traxxas, Team Associated, HPI, Team Losi and other manufacturers. Always verify your shock length before purchasing.
- How do I choose between soft, medium and hard springs? — Start with the medium spring as a baseline. If your car feels too bouncy and unstable, try the hard spring for more support. If it feels too stiff and loses traction, try the soft spring for improved grip and comfort. Your choice may also depend on driving style, terrain and personal preference.
