RC4WD Internal Springs for Superlift 100mm Scale Shock Absorbers Z-S1183

Overview

Fine-tune your RC crawler or trail truck setup with the RC4WD Internal Springs for Superlift 100mm Shocks (Z-S1183). Whether you're a serious scale crawler enthusiast or a weekend basher looking to dial in the perfect suspension feel, this comprehensive spring pack gives you the flexibility to adjust damping and ride height across a wide range of applications. These internal springs are specifically engineered to work with RC4WD's renowned Superlift shock absorber systems, allowing you to optimise performance for different terrain types, weather conditions and driving styles. As an authorised RC4WD retailer, RC Model Shop stocks this essential upgrade component for UK RC enthusiasts who demand precision and quality in their scale crawler builds.

Suspension tuning is one of the most effective ways to improve your RC vehicle's handling characteristics, and this spring set makes it accessible to everyone. Instead of being locked into a single spring rate, you get multiple options colour-marked for instant identification, so swapping springs between shocks takes just minutes. Whether you need a softer setup for smooth crawling over delicate obstacles, or stiffer springs for aggressive bashing on rough terrain, this kit provides the range you need. Each spring is precisely manufactured to RC4WD's exacting standards, ensuring consistent performance across all four shocks on your rig.

The Z-S1183 represents excellent value for money and is an investment in getting the absolute best from your RC4WD Superlift shocks. Rather than purchasing an entirely new shock assembly, these replacement springs let you experiment with different setups until you find the perfect balance for your driving style and local terrain. For RC car enthusiasts in the UK looking to improve their crawler's performance, this is a must-have upgrade.

Key Features

• Complete four-shock set — This pack contains enough springs to outfit all four shocks on your scale crawler or trail truck, eliminating the need to source components from multiple suppliers and ensuring consistency across your entire suspension system.
• Four different spring rates included — You receive springs rated at 1.9, 1.5, 0.7 and 0.3, giving you genuine flexibility to experiment and find the optimal setup for different terrain and driving conditions rather than being restricted to a single spring rate.
• Colour-coded for easy identification — Each spring rate is marked with a distinct colour (Blue for 1.9, Red for 1.5, White for 0.7, Yellow for 0.3), making it simple to quickly identify which springs you're installing and eliminating confusion during setup adjustments.
• Direct fit compatibility with Superlift shocks — These springs are engineered specifically for RC4WD Superlift Superide 100mm scale shock absorbers (Z-D0032), ensuring perfect fitment without modification or adapter parts.
• Lightweight precision engineering — At just 2g per spring (0.07oz), these components are optimised for minimal unsprung weight, which is critical for maintaining traction and responsiveness in scale crawling applications where every gram counts.
• Compact and manageable dimensions — With an outer diameter of 6.3mm and length of 42mm, these springs fit neatly within the shock body while delivering the spring rates needed for serious suspension tuning.

Technical Performance

The RC4WD Internal Springs for Superlift 100mm Shocks represent a significant step up in suspension customisation for scale RC crawlers and trail trucks. The inclusion of four distinct spring rates — 1.9, 1.5, 0.7 and 0.3 — allows you to dial in damping characteristics across a broad spectrum of applications. The stock Superlift shock spring rate is 0.45, so this kit provides options both softer and significantly stiffer, giving you the ability to tune for everything from delicate technical terrain where a softer setup maintains compliance, through to aggressive high-speed bashing where stiffer springs maintain ride height and control. The precision manufacturing ensures that springs of the same rate deliver identical performance, critical for balanced suspension geometry across all four wheels. Each spring measures 42mm in length with a 6.3mm outer diameter and 4.1mm inner diameter, engineered to fit seamlessly within the Superlift shock design. The colour-marking system on the bottom of each spring eliminates guesswork during setup changes, particularly valuable when you're testing different configurations on a test course or during competition. For UK-based RC car hobbyists, these springs represent an affordable way to unlock the full potential of your Superlift shock system without purchasing new shocks entirely.

Frequently Asked Questions

• What is the stock spring rate for Superlift 100mm shocks? — The standard stock spring rate is 0.45. This kit includes springs rated at 1.9, 1.5, 0.7 and 0.3, giving you options both above and below the stock rate so you can tune your suspension precisely.
• How do I know which spring rate to use? — Start with the stock 0.45 rate as your baseline. If your crawler feels too soft and wallows in corners, try a stiffer rate like 0.7, 1.5 or 1.9. If it feels too stiff and loses traction over obstacles, try a softer rate like 0.3. The colour markings make it easy to remember which is which.
• Will these springs fit my RC4WD Superlift Superide 100mm shocks? — Yes, these are engineered as direct replacements for the RC4WD Superlift Superide 100mm Scale Shock Absorbers (Z-D0032). They will not fit other shock brands or different shock lengths without potential fitment issues.
• Can I use different spring rates on different shocks? — While it's possible, this is generally not recommended as it will create uneven suspension geometry and weight distribution. For best results, use the same spring rate on all four shocks, then adjust all four together if needed.
• How often will I need to replace these springs? — Springs rarely wear out completely but may lose some stiffness over many years of heavy use. For most hobby users, these springs should last for years of regular driving. They're sold as a set so you can replace all four when needed.
• Are these suitable for beginners? — Yes, the colour-coded system makes these very beginner-friendly. Installation is straightforward, and the included range of spring rates means beginners can experiment safely to find the setup that works best for them without needing specialist knowledge.
• What makes spring rate selection important for RC crawlers? — Spring rate directly affects how your crawler handles different terrain. Softer springs compress more easily, maintaining traction over obstacles but potentially causing wallowing. Stiffer springs resist compression, maintaining ride height and control but potentially breaking traction. The right balance depends on your terrain, driving style and vehicle weight.
