Red Spider R403 LS3 V8 Simulated Engine Cooling Fan, 1/10 RC Crawler Engine Bay Upgrade Parts, Compatible with TRX4, SCX10, D90 XQJ-021

Product Overview

• This 2-in-1 upgrade part is launched by Red Spider, perfectly replicating the appearance of the classic American Corvette LS3 V8 engine in 1/10 scale, with a built-in high-speed cooling fan to balance ultra-realistic looks and practical heat dissipation performance. The red & silver two-tone painted body features separately molded details including intake manifold, ignition coils, segmented air runners, engine block textures, pipelines and bolts. Once you open the car hood, it creates an immersive hardcore off-road engine bay view. The hidden cooling fan continuously blows air to cool down your motor and ESC, solving power overheating and performance drop issues during long trail climbs or heavy-load crawling. It is a top-tier engine bay mod for all 1/10 scale realistic RC crawlers.

Key Features

• Hyper-Detailed LS3 V8 Engine Scale Replica
  It precisely replicates the shape of classic American LS3 V8 8-cylinder engine. Every component including silver curved intake manifold, black split ignition coils, wavy air intake runners, high-voltage pipelines and casting block textures is molded separately. Layered glossy paint in red, black and silver delivers premium metallic texture, with crisp details of bolts and pipe joints, no cheap plastic look. It performs excellently for static display and diorama shooting, matching military off-road, overland and post-apocalyptic modified body styles perfectly.
• Built-in Active Cooling Fan, Decor & Function All-in-one
  A silent high-speed cooling fan is hidden inside the engine housing, matched with a 265mm long power wire with plug, which can be directly connected to the spare power channel of your ESC. The fan runs continuously while driving or crawling, covering the core heat-generating area of motor and ESC to dissipate heat efficiently. It prevents power speed reduction and electronic component aging damage caused by overheating after long off-road runs, turning a simple decorative piece into a functional performance upgrade.
• Lightweight Universal Mount Base, Fits All 1/10 Crawlers
  Overall dimension: 62mm × 65mm × 52mm, unit weight only 48g. The lightweight design will not add extra front-end weight or change the vehicle weight balance. The integrated curved bottom bracket requires no large-scale cutting or sanding on the car body, easy to secure with screws or cable ties. It is fully compatible with all mainstream 1/10 scale realistic crawlers on the market: Traxxas TRX4/TRX6, Axial SCX10 II/III, RC4WD D90, Capo Jimny, Tamiya CC01, fits both stock engine bays and modified wide-body bays.
• Heavy-Duty Wear-Resistant ABS, Support Custom Modification
  The whole unit is integrally injection molded with thickened high-toughness ABS engineering plastic, resistant to cracks and impacts from gravel and bumpy off-road trails. High-temperature baked paint has strong adhesion, no fading or whitening after mud and rain splashes. Ignition coils, high-voltage pipelines and air intake parts are all detachable independent pieces, allowing hobbyists to freely adjust angles and rework pipelines for exclusive customized engine bay builds.
