Rock racing demands precision engineering and robust components that can withstand the stresses of competitive off-road driving. The rear trailing arms form a critical part of your RC car's suspension linkage system, connecting the chassis to the rear axle housing and controlling vertical wheel movement whilst maintaining lateral alignment. When these components wear, crack or become damaged through intensive use, replacement is essential to restore your rock racer's original handling characteristics and ensure consistent performance on the track or field. These genuine RC4WD parts are manufactured to exacting standards and are the perfect choice for both weekend bashers and serious competitors who demand nothing but the best from their RC rock crawlers and racing platforms.

Key Features

• Strong Durable Nylon Construction — These trailing arms are manufactured from high-quality nylon material that provides excellent strength-to-weight ratio, crucial for maintaining responsive handling without adding unnecessary mass to your 1/10 scale rock racer. Nylon's inherent durability means these arms resist impact damage better than some alternative materials, making them ideal for the rough and tumble world of rock racing where components face constant punishment from rocks, roots and uneven terrain.
• Matched Left and Right Pair — The set includes both left and right trailing arms, pre-matched and manufactured to identical specifications to ensure perfect symmetry in your suspension geometry. This pairing guarantees balanced handling characteristics across both sides of your vehicle, essential for predictable cornering and stable braking performance in competitive rock racing scenarios.
• Lightweight Design at Just 22.8g Total — Combined weight of only 0.80oz (22.8g) for the complete pair keeps unsprung weight low, a critical factor in rock racing where light suspension components improve wheel compliance and traction. Lower unsprung mass allows your tyres to maintain better contact with the track surface, especially important when navigating rocky, technical terrain where every ounce of traction matters.
• OEM Quality and Direct Fitment — As genuine RC4WD parts, these trailing arms are engineered to exact specifications for seamless installation into the Miller Motorsports Pro Rock Racer platform, eliminating any guesswork or compatibility concerns. You get the same components originally supplied with new models, guaranteeing fitment and performance.
• Authorised RC4WD Parts — Purchased through RC Model Shop as an authorised RC4WD retailer, you receive genuine parts backed by manufacturer warranty and support, protecting your investment in quality RC equipment.

Technical Performance

The RC4WD Z-S0687 rear trailing arms represent precision engineering optimised for the specific geometry and suspension requirements of the Miller Motorsports 1/10 Pro Rock Racer platform. Manufactured from engineering-grade nylon, these components deliver the strength necessary to withstand the rigours of rock racing whilst maintaining the lightweight characteristics essential for responsive handling. At just 22.8g total weight for the complete left and right pair, these trailing arms represent a minimal addition to your vehicle's unsprung weight, allowing for maximum suspension compliance and traction on uneven terrain. The nylon material provides excellent impact resistance compared to some softer plastics, making these arms particularly suited to the demanding environment of UK rock racing venues where sharp rocks and technical obstacles are commonplace. The design maintains the precise suspension geometry required for the Miller Motorsports platform, ensuring that wheel travel, camber changes and anti-squat characteristics remain within the manufacturer's specifications for optimal handling balance. Whether you're rebuilding your rock racer after an accident or performing routine maintenance on a well-used competition vehicle, these genuine OEM parts restore your suspension to factory-standard performance.

Frequently Asked Questions

• What vehicle do these trailing arms fit? — These RC4WD Z-S0687 rear trailing arms are specifically designed for the RC4WD Miller Motorsports 1/10 Pro Rock Racer RTR (model Z-RTR0061). Before purchasing, confirm you own this exact platform to ensure perfect compatibility and fitment.
• Why would I need replacement trailing arms for my rock racer? — Rear trailing arms are suspension components that wear, crack or break through intensive use, especially in competitive rock racing where vehicles encounter sharp rocks, jumps and technical obstacles. When damaged, they must be replaced to restore your vehicle's handling characteristics and suspension geometry. Even small cracks or bends in these arms can significantly affect your rock racer's performance on demanding terrain.
• Are these genuine RC4WD parts or aftermarket alternatives? — These are 100% genuine OEM RC4WD parts, manufactured to the exact specifications required for the Miller Motorsports platform. Purchasing through RC Model Shop as an authorised RC4WD retailer guarantees you receive authentic components backed by the manufacturer, not inferior aftermarket imitations that might not fit correctly or perform as well.
• How much do these trailing arms weigh and why does that matter? — The complete pair weighs just 22.8g (0.80oz), which is critically important in rock racing where lower unsprung weight improves suspension compliance and traction. Lighter suspension components allow your tyres to maintain better contact with rocky, uneven terrain, directly translating to improved grip and more predictable handling characteristics in competition.
• Can I install these myself or do I need professional help? — Installation difficulty depends on your mechanical experience and familiarity with RC car suspension systems. The trailing arms connect to the chassis and rear axle housing using bolts or pins, so basic mechanical knowledge and appropriate tools are recommended. If you're uncertain about installation, RC Model Shop's team can provide guidance or you may prefer to have the work completed by an experienced RC technician.
• Are these parts covered by warranty? — As genuine RC4WD components purchased from an authorised retailer, these parts are covered by RC4WD's manufacturer warranty against defects in materials and workmanship under normal use conditions. RC Model Shop provides support and can help arrange warranty claims if required.
• Do I need to buy anything else to complete my repair? — Depending on your specific situation, you may need replacement fasteners (bolts, pins or screws) if the original mounting hardware is damaged during removal, though most users find the existing hardware can be reused. You'll also need appropriate tools such as hex keys or screwdrivers to remove the old arms and install the new ones.
