RC4WD THE ULTIMATE SCALE SHOCKS 90MM (SILVER) Z-D0001

Overview

The RC4WD Ultimate Scale Shocks 90mm (Silver) Z-D0001 represents the pinnacle of suspension engineering for scale RC crawlers and off-road vehicles across the UK and beyond. These precision-crafted shock absorbers are engineered specifically for modellers who demand the highest standards of scale authenticity combined with genuine performance. Whether you're running a Traxxas TRX-4, RC4WD Trail Finder 2, or Gmade Sawback, these shocks deliver the smooth, realistic suspension action that separates serious scale builders from casual enthusiasts.

At just 8.8mm outer diameter, these are recognised as the most scale and precision-made suspension shocks available on the market today. Supplied as a pair, they feature next-generation super-soft internal springs engineered for smooth articulation and realistic scale movement. If you're serious about scale accuracy in your RC car UK build, these shocks should be on your shopping list. The combination of premium materials, precision manufacturing, and thoughtful engineering makes them an essential upgrade for anyone building a realistic scale crawler or rock crawling RC vehicle.

Unlike many budget shock absorbers, the RC4WD Ultimate Scale Shocks are CNC-machined from billet aluminium and heat-treated for durability, ensuring they'll handle thousands of articulations without losing their smooth action. The super-soft internal springs are tuned to provide realistic suspension travel while maintaining stability, making these ideal for scale terrain vehicles, trail trucks, and dedicated crawlers.

Key Features

• CNC-Machined Billet Aluminium Construction — Every shock body is precision-machined from solid billet aluminium and heat-treated to enhance durability and resistance to wear, ensuring these shocks maintain their performance characteristics over extended use in demanding RC applications.
• Next-Generation Super-Soft Internal Springs — The custom-tuned springs provide smooth, progressive suspension action that closely mimics full-size vehicle behaviour, delivering realistic articulation that scale enthusiasts demand whilst maintaining vehicle stability across varied terrain.
• Exceptional Scale Proportions — With an 8.8mm outer diameter shock body, these are the most scale-correct suspension components available for 1/10-scale crawlers and rock crawling vehicles, maintaining visual authenticity whilst delivering genuine performance.
• Precision Ball Joints — The 6.45mm ball width with 4.8mm lip outer diameter and 3.1mm inner diameter provide smooth articulation and reduced friction, ensuring responsive suspension movement without binding or catching.
• Compact Shaft Design — The 3mm outer diameter shaft minimises visual bulk whilst maintaining structural integrity, contributing to the overall scale appearance when installed on your RC crawler or scale truck.
• Smooth Travel Characteristics — With 24mm of travel (compressed length 68mm, uncompressed 90mm), these shocks provide realistic suspension drop and compression, essential for scale terrain vehicles navigating realistic obstacles.
• Lightweight Construction — Each shock weighs just 11 grams, minimising unsprung weight and improving overall vehicle handling without adding unnecessary mass to your RC crawler or scale truck.
• Supplied as a Pair — Each package includes two complete shock absorbers, perfect for upgrading a single axle or combining multiple sets for complete vehicle suspension refresh.

Technical Performance

These shocks represent a significant step forward in scale RC suspension technology. The CNC-machined billet aluminium construction provides the structural rigidity needed to handle real-world terrain whilst maintaining the precise tolerances essential for smooth operation. The heat treatment process increases hardness and fatigue resistance, critical when you're running thousands of suspension cycles across rocky terrain or technical obstacles. The super-soft internal springs are engineered to work in harmony with the shaft design, delivering smooth compression and extension without harshness or binding. At 8.8mm outer diameter, they're substantially smaller than typical shock absorbers, allowing them to fit within realistic suspension mounting points on scale crawlers like the Traxxas TRX-4, RC4WD Trail Finder 2, and other precision scale vehicles. The 3mm shaft diameter provides excellent bearing surface area relative to its compact size, reducing wear and extending service life. The precision ball joints with their carefully calculated dimensions ensure that suspension movement remains smooth and predictable across the full 24mm travel range. Whether you're tackling rocky terrain, scaling rock faces, or navigating technical obstacles, these shocks deliver the controlled, realistic suspension performance that distinguishes high-end scale vehicles from basic RC cars.

What's in the Box

• 2x RC4WD Ultimate Scale Shock Absorbers (90mm, Silver)

What You Need to Complete

• Two sets of these shocks are needed to completely equip a full vehicle (front and rear axles)
• For installation on Traxxas TRX-4, you will require 2mm (Z-S0600) and 3mm (Z-S0806) Black Spacers with M3 Holes
• Replacement springs are available separately: 90mm Ultimate Scale Shocks Internal Spring Assortment (Z-S1349)
• Small amount of light oil for shaft lubrication during installation and maintenance
• Medium (blue) thread lock for securing the bottom shock shaft rod end before installation

Installation and Maintenance Notes

These shocks do not use oil for damping — only apply a small amount to lubricate the shaft during installation and maintenance. Use medium (blue) thread lock on the bottom shock shaft rod end before installing onto your vehicle to keep it securely in place. Pay careful attention when installing shock caps, as the fine threads can strip if misaligned or forced. Install the cap carefully and ensure threads are properly aligned before tightening. If you need to replace the internal springs, the 90mm Ultimate Scale Shocks Internal Spring Assortment (Z-S1349) is available as a separate purchase.

Compatibility

These 90mm shocks are designed to fit specific vehicles. Confirmed compatibility includes the Gmade Sawback (front and rear), RC4WD Timberwolf Scale Crawler Kit with Bolted Chrome finish (Z-K0016) for front and rear installation, RC4WD Trail Finder 2 Truck Kit with Mojave Body (Z-K0042) for rear installation, and RC4WD Trail Finder 2 Truck Kit with Mojave II Body (Z-K0049). For Traxxas TRX-4 installation, compatibility is confirmed but requires the addition of both 2mm (Z-S0600) and 3mm (Z-S0806) Black Spacers with M3 Holes. Always check vehicle-specific fitment before ordering if your model is not listed.

Frequently Asked Questions

• Are these shocks suitable for a beginner RC modeller? — Whilst these shocks are straightforward to install, they're specifically engineered for experienced scale modellers who understand shock tuning and maintenance. If you're new to RC, they'll work perfectly once installed, but you should be familiar with basic suspension maintenance. The fine threads on the shock caps require careful handling during installation, so read the instructions thoroughly before fitting.
• What makes these shocks different from standard RC shock absorbers? — The RC4WD Ultimate Scale Shocks are purpose-built for scale authenticity and performance. At 8.8mm outer diameter, they're considerably smaller than typical shock absorbers, allowing them to mount within realistic suspension geometry on scale crawlers. The CNC-machined billet aluminium construction and heat treatment provide superior durability and precision compared to budget alternatives, and the next-generation super-soft springs deliver the smooth, realistic articulation that separates high-end scale vehicles from basic RC cars.
• How often do these shocks need maintenance? — The shocks require minimal maintenance. Ensure the shaft remains lightly lubricated (using only a small amount of oil), and periodically check that shock caps remain tight and securely fastened. The super-soft springs maintain their characteristics indefinitely, but if you want to experiment with different spring rates, replacement springs are available separately.
• Can I use these shocks on other vehicles besides the ones listed? — The 90mm hole-to-hole dimension is your key measurement. If your vehicle has suspension mounts approximately 90mm apart when fully uncompressed, these shocks should fit. However, you may need additional spacers or brackets depending on your specific vehicle. Always verify measurements before purchasing to avoid compatibility issues.
• Do these shocks work with oil-damped suspension systems? — No, these shocks are designed to work without oil damping. The super-soft internal springs provide all the damping characteristics. Only apply a small amount of light oil for shaft lubrication, never for damping purposes.
• What is the difference between the 90mm and other shock sizes offered? — The 90mm refers to the uncompressed hole-to-hole measurement. This size is engineered specifically for vehicles with 90mm suspension mounting distances when fully extended. Choosing the correct length is critical for proper vehicle geometry and suspension performance. The 24mm travel range of this 90mm shock may differ from other sizes, so always verify your vehicle's requirements before ordering.
