Product for 1/10 RC Crawler TRX-4 TRX4 — Aluminum alloy metal upgrade kit Key benefits Durable metal construction: Precision-machined aluminum alloy parts replace weaker stock components to reduce wear and breakage under heavy use. Improved handling and stability: Upgraded suspension components and linkages deliver better shock absorption, more precise steering response and smoother operation across varied terrain. Reliable, precise fit: Each part is engineered to match popular 1/10 TRX-4/TRX4 mounting points for straightforward integration with your existing setup. What’s included / main components Metal suspension arms (upgrade for stock plastic arms) Metal shocks / shock caps and related hardware Steering components such as steering knuckles/steering sleeves Driveshaft/driveshaft components Why you need this upgrade Prevents frequent part failures: Metal parts resist wear and impact better than stock plastic, reducing maintenance and downtime. Better control on rough terrain: Stronger suspension parts and improved shock performance keep tires planted and steering predictable. Long-term value: Robust components extend the life of the vehicle and support more aggressive trail use. Material and compatibility Material: High-quality aluminum alloy for strength and wear resistance Scale/fit: Designed specifically for 1/10 RC Crawler TRX-4 TRX4 models Installation: Parts are dimensioned for a precise fit with existing mounting points to allow a straightforward replacement of stock components Performance characteristics Enhanced shock absorption that reduces chassis stress and improves traction More precise steering inputs and reduced flex from upgraded linkages Smoother drivetrain operation from sturdier driveshaft components Practical use scenarios Rock crawling: Replace fragile plastic parts before a technical rock run to prevent part failure and maintain precise wheel control on uneven surfaces. Trail running and overlanding: Use the kit for longer trail outings where repeated impacts and rough ground demand tougher suspension and steering components. Hobbyist upgrades and maintenance: Install as a planned durability upgrade to improve confidence and reduce repair frequency during club events or practice sessions. Notes on installation and performance Designed for bolt-in replacement of common suspension and steering parts on TRX-4/TRX4 models; basic tools and mechanical familiarity recommended. Improves durability and handling without modifying vehicle geometry; check fit and fastener torque during installation. This metal upgrade kit provides a durable, precision-fit option to enhance the longevity, handling, and reliability of your 1/10 TRX-4/TRX4 RC crawler under demanding conditions.
