Overview

The RC4WD Rancho RS9000 XL Shock Absorbers 90mm (Z-D0078) represent a significant leap forward in scale RC realism and performance for serious crawlers and trail trucks. These officially licensed scale dampers bring authentic Rancho suspension styling to your RC4WD scale build, combining museum-quality aesthetics with genuine functional performance on the rocks. Whether you're building a competitive scale crawler, a weekend trail truck, or a detailed showpiece RC car UK enthusiasts will appreciate, these shocks deliver the perfect balance of visual authenticity and reliable damping across rocky, technical terrain.

Built from the ground up with a completely new design philosophy, the Rancho RS9000 XL shocks have been engineered specifically for the demands of modern RC scale crawling. These are not simply cosmetic upgrades – they feature precision machined billet aluminium construction and an innovative internal spring design that keeps your build looking clean and scale-accurate whilst providing smooth, consistent suspension action. The shocks are available only from RC4WD and their authorised dealers, making them an exclusive upgrade for serious RC enthusiasts who refuse to compromise on quality or authenticity.

The 90mm uncompressed length makes these shocks ideal for a wide range of popular RC4WD platform vehicles, including the Trail Finder 2 and Gelande II ranges. For those running different chassis configurations, RC4WD also produces the same shocks in 80mm and 100mm variants, ensuring you can find the perfect fit for your specific setup.

Key Features

• Officially Licensed Rancho Design — These shocks are authentically licensed from the real Rancho suspension company, meaning you get the genuine visual styling and branding that serious scale enthusiasts demand. The Rancho name carries decades of off-road credibility, and having properly licensed components elevates the entire aesthetic of your scale build.
• Machined Billet Aluminium Construction — Rather than using plastic or stamped materials, every shock body is precision machined from solid billet aluminium, delivering exceptional durability and a premium feel that catches the light beautifully on display or on the trail. This manufacturing approach ensures consistent quality and longevity, even under the demanding stresses of technical rock crawling.
• Internal Spring Design — The innovative internal spring layout keeps your shocks looking completely scale-correct and visually clean from every angle, with no exposed coil springs cluttering the appearance. This thoughtful engineering choice means your suspension components won't distract from your scale body's details, maintaining that factory-stock aesthetic you've worked hard to achieve.
• Smooth, Consistent Performance — The internal spring design works seamlessly with the precision machined construction to deliver smooth damping action across all terrain types, from gentle rolling hills to brutal rocky obstacles. You'll experience reliable, predictable suspension behaviour that responds consistently throughout your driving sessions.
• Purpose-Built for Technical Terrain — These shocks have been specifically engineered to cope with rocky, technical terrain, making them ideal for scale crawlers tackling challenging off-road courses and obstacle courses. The design handles dramatic articulation and extreme suspension compression without binding or performance degradation.
• Clean Scale Appearance — With their tidy packaging and scale-correct proportions, these shocks integrate seamlessly into your RC4WD build without standing out as obviously aftermarket parts. Whether viewed from above, the side, or up close, they maintain authentic styling that complements your scale body perfectly.

Technical Performance

The RC4WD Rancho RS9000 XL Shock Absorbers represent serious engineering excellence that goes well beyond simple visual upgrades. Each shock is individually precision machined from billet aluminium, a manufacturing process that takes significantly more time and cost than alternative production methods but delivers uncompromising quality. The 90mm uncompressed hole-to-hole measurement (with 70mm measurement when fully compressed) provides 20mm of travel length, offering the sweet spot between realistic proportions and functional suspension articulation needed for scale crawling. At just 11 grams each (0.38 ounces), the weight penalty is minimal, helping preserve the overall balance and handling characteristics of your RC4WD platform vehicle. The shock body features a compact 10mm outer diameter with a 3.5mm shaft diameter, proportions that look authentically scale-correct on 1/10 scale vehicles. The overall length of 98.2mm, combined with the internal spring design, ensures these shocks fit perfectly within scale chassis layouts whilst providing the damping performance needed for demanding terrain. Whether you're running them on a Trail Finder 2, Gelande II, or compatible RC4WD platform, these shocks will immediately be noticeable for their superior quality and attention to detail compared to basic damper designs.

Frequently Asked Questions

• Are these shocks suitable for my RC4WD scale crawler build? — Yes, these shocks are specifically engineered for RC4WD scale crawlers and trail trucks. The 90mm length is ideal for the popular Trail Finder 2 and Gelande II platforms. If you need a different length, RC4WD also produces 80mm and 100mm variants. Always verify your specific model's compatibility from the compatibility list above before purchasing.
• What makes these shocks different from standard dampers? — The key differences are the officially licensed Rancho design, precision machined billet aluminium construction, and innovative internal spring design. Standard shocks often use plastic bodies and external springs, whereas these feature premium materials and thoughtful engineering that delivers both visual authenticity and reliable performance. The internal springs also contribute to the clean scale appearance that serious RC enthusiasts demand.
• How much do individual shocks weigh? — Each shock weighs just 11.0 grams (0.38 ounces), making them lightweight enough to preserve your vehicle's balance and handling whilst delivering the durability and quality of machined billet construction. This represents an excellent weight-to-durability ratio for scale crawlers.
• What are the exact dimensions I need to know? — The shocks measure 3.54 inches (90mm) hole-to-hole when uncompressed, compress down to 2.76 inches (70mm), with an overall length of 3.86 inches (98.2mm). They provide 0.78 inches (20mm) of travel and feature a 0.39-inch (10mm) shock body diameter with a 0.13-inch (3.5mm) shaft diameter. These proportions are specifically sized for 1/10 scale RC4WD vehicles.
• Do I need to purchase two sets of these shocks? — Yes, to complete a full suspension upgrade for all four wheels of your RC vehicle, you will need to purchase two sets of this product (giving you four shocks total). One set contains two shocks, enough for either the front or rear suspension.
• Are these shocks waterproof? — The source information does not specify waterproof ratings for these shocks. We recommend contacting our customer service team on 01543 577278 or via WhatsApp for detailed information about water resistance and maintenance recommendations.
• How do these compare to the 80mm and 100mm variants? — The 90mm version offers the middle ground for uncompressed length. The 80mm variant (Z-D0077) is slightly shorter and may suit vehicles requiring a lower ride height, whilst the 100mm variant (Z-D0079) is taller and works for setups needing more suspension clearance. All three share the same quality machined aluminium construction and Rancho licensing. Choose based on your specific chassis requirements.
• What terrain are these shocks designed for? — These shocks have been specifically engineered to cope with rocky, technical terrain, making them ideal for scale crawling applications, obstacle courses, and challenging off-road courses. The internal spring design and billet construction handle dramatic articulation and extreme compression without binding or degradation.
