Technical Performance

The Traxxas Spring, shock (Red) (3.7 rate) represents precision suspension engineering at its finest, manufactured from premium spring steel that delivers consistent performance lap after lap. The spring rate of 3.7 places these springs in the mid-to-stiff category of the Traxxas suspension lineup, providing a noticeable increase in suspension stiffness compared to lower-rate springs whilst remaining accessible for general driving and track use. The powder-coated red finish not only provides visual appeal but also offers protection against corrosion and environmental degradation, ensuring long-term durability even when exposed to moisture, mud and variable UK weather conditions. These springs are designed to work seamlessly with the short Ultra Shock dampers featured on the 4-TEC 3.0, and the matched pair allows you to maintain balanced suspension geometry across both front and rear axles. Higher spring rates like this 3.7 rate generally result in stiffer suspension response, reduced body roll during cornering, improved stability on high-grip surfaces, and better control when driving on rough or uneven terrain. The difference between spring rates is measurable and noticeable in real-world driving conditions—upgrading from a softer rate to a 3.7 will tighten up your handling noticeably. For competitive drivers and serious RC enthusiasts seeking to extract maximum performance from their 4-TEC 3.0 Corvette Stingray, having multiple spring rates available for experimentation is essential. These springs represent an affordable yet critical component of any RC modeller's tuning and spares collection.

Frequently Asked Questions

• What is a spring rate and why does it matter for my RC car? — The spring rate, measured in units like 3.7, determines how stiff the spring is. A higher rate means a stiffer spring that resists compression more strongly. This matters because stiffer springs reduce body roll during cornering, improve stability on high-grip tracks, and help maintain consistent suspension geometry. Softer springs absorb bumps better and provide more grip on loose or bumpy terrain. Finding the right spring rate for your driving style and track conditions is one of the most effective ways to improve your RC car's handling.
• Will these springs fit my 4-TEC 3.0? — Yes, these springs are specifically designed for the Traxxas 4-TEC 3.0 Chevrolet Corvette Stingray (both TRX93054-4-BLK in black and TRX93054-4-SLVR in silver versions). They fit the short Ultra Shock dampers used on the 4-TEC 3.0 platform. If you own a 4-TEC 3.0, these springs will install directly into your existing shock assemblies without any modification.
• What is the difference between this 3.7 rate and other Traxxas spring rates? — Traxxas offers multiple spring rates for the 4-TEC 3.0, ranging from softer to stiffer options. The 3.7 rate sits in the mid-to-stiff range. Lower rates (softer springs) provide more suspension compliance and grip on bumpy tracks but allow more body roll. Higher rates (stiffer springs) reduce body roll, improve stability, and tighten handling but can feel less forgiving on rough terrain. The 3.7 represents a balanced option suitable for mixed conditions and general driving.
• How do I know if I need stiffer springs? — You might benefit from upgrading to stiffer springs like this 3.7 rate if your current setup experiences excessive body roll during cornering, if you want better stability on high-grip surfaces, if you are running a heavier vehicle configuration, or if you want more predictable handling for competitive driving. Conversely, if your 4-TEC feels too stiff and harsh over bumps, or if you want more grip on loose terrain, you might want to try softer springs.
• Are these genuine Traxxas parts? — Yes, the TRX8362 is a genuine OEM Traxxas replacement part manufactured to exact factory specifications. When you order from RC Model Shop, an authorised Traxxas retailer, you are guaranteed authentic Traxxas components with full compatibility and quality assurance.
• How many springs do I get in this pack? — This pack contains two springs, providing a matched pair for replacing the front and rear springs or for maintaining a spare set. Two springs are typically the minimum you need to refresh your suspension geometry.
• Can I use different spring rates front and rear? — Yes, many RC enthusiasts run different spring rates on the front and rear to fine-tune weight distribution and handling balance. However, most competitive drivers prefer matched rates for consistency. Experimenting with different front and rear rates is a great way to dial in your specific handling preference.
• What is included in the box? — The TRX8362 pack contains two genuine Traxxas shock springs in red with a 3.7 spring rate. Nothing else is included; these are replacement springs only.
