Best for: RC enthusiasts replacing worn springs on Traxxas systems that require a direct, compatible fit. Limitations: data does not specify exact rate numbers, so fine-tuning might require additional reference for precise setup.
Pro-Line Racing PowerStroke Shocks Rear Spring Assortment PRO606304
Pro-Line’s PowerStroke shock rear spring assortment includes six primary black/short springs and six secondary silver/long springs with color-coded stripes to identify rates. This set is ideal for drivers who want a broad range of spring rates in one package for rear-end tuning and improved traction on varied surfaces.
Best for: riders seeking a versatile, color-coded upgrade to fine-tune rear damping. Caution: compatibility varies by model; verify your shock mount geometry before pairing with this assortment.
Traxxas 7442 GTR XX-Long Shock Springs
The Traxxas 7442 XX-Long springs offer extended travel with a distinct orange rate for heavier damping needs. This makes them suitable for vehicles that run long-travel systems or require extra rebound control over rough terrain and jumps.
Best for: drivers who push aggressive terrain and need longer, higher-rate springs. Limitation: data does not include exact rate numbers; pairing with a model-specific shock kit is recommended to ensure fit and function.
MOSHNOLY Bearing Steel Shock Absorbers Spring
MOSHNOLY offers bearing steel springs with thicker wire (1.8 mm) for front 95mm and rear 100mm shocks. The thicker wire improves resistance to slow rebound and reduces chassis scraping during aggressive cornering. The nickel-plated surface provides rust resistance and smoother installation.
Best for: enthusiasts needing durable, corrosion-resistant springs with improved high-load handling. Caution: exact compatibility should be confirmed for your front/rear shock lengths before purchase.
INJORA Metal Shock Spring Set 1/10 Scale
INJORA’s metal shock spring set provides five colors and easy installation. Made from quality metal, the set aims at durability with straightforward color-coding to match different spring rates. This set is appropriate for 1/10 scale RC cars and those seeking a budget-friendly, durable upgrade.
Best for: beginners and intermediate builders who want an affordable, durable color-coded spring kit. Limitation: data lacks exact spring rates; expect to pair with trial-and-error tuning for precise setup.
Buying Guide
What to consider when choosing big bore shock springs
- Vehicle compatibility: Check shock length (front/rear) and diameter to ensure a proper fit with your model.
- Spring rate and wire thickness: Higher rates and thicker wires yield stiffer damping and less rebound; match to terrain and driving style.
- Travel and geometry: Longer springs support longer travel; verify your chassis’s suspension travel to avoid binding.
- Material and finish: Bearing steel and nickel plating resist wear and corrosion; consider maintenance implications in mud or water.
- Color-coding and set variety: Sets with multiple rates let you tune without purchasing individual springs.
- Ease of installation: Look for springs with smooth ends and compatible mounting hardware for quick setup.
How to compare options quickly
- Best for direct compatibility with a known model: Traxxas 7449 or 7442 for Traxxas systems.
- Best for rear-tuning flexibility: Pro-Line PowerStroke Rear Spring Assortment.
- Best for durability under heavy use: MOSHNOLY bearing steel springs.

Frequently asked questions
- What is a big bore shock spring? A larger-diameter spring that works with bigger, longer-travel shocks to provide improved damping and stability.
- How do I know which spring rate I need? Rates depend on vehicle weight, tire size, terrain, and ride height. Start with mid-range, then adjust based on ride feel and handling.
- Are metal springs better than standard springs? Metal springs offer durability and consistent performance under demanding use, but may be heavier; consider the weight balance on your chassis.
- Can I mix spring rates front and rear? Yes, mixing rates can tune steering balance and weight transfer, but changes should be tested in controlled conditions.
- Should I replace all springs at once? Replacing in sets ensures consistent damping across corners, which helps predictable handling.
- Do these springs affect warranty? Warranty terms vary by brand and retailer; check model-specific guidance before upgrading components.
