Key Features
- Over 35% Ground Clearance Increase — When combined with the recommended Mickey Thompson Baja Pro XS 2.4x1.0 inch tyres, this kit raises your TRX-4M's centre ground clearance by more than a third, allowing you to traverse larger obstacles, deeper ruts and more challenging terrain whilst maintaining control and stability.
- Revised Shock Mounts — The kit includes specially engineered shock mounting brackets that accommodate the increased suspension travel and geometry changes, ensuring optimal damping performance and ride comfort across rocks, logs and uneven ground.
- Longer Suspension Links — Extended suspension linkages maintain the critical geometry of your TRX-4M's suspension system, preserving proper Ackermann steering geometry and suspension angles so your RC crawler steers predictably and suspends weight evenly even with the increased height.
- Extended Trailer Hitch — A lengthened trailer hitch is included in the complete kit, allowing you to continue using accessories and recovery gear without interference from the lifted chassis, maintaining full functionality of your TRX-4M setup.
- Aggressive Stance — Beyond pure performance, the dramatic lift transforms your TRX-4M's visual presence, giving it a purposeful, competition-grade appearance that commands attention on the crawling course or in your workshop.
- Complete Kit Design — Everything you need for installation is included in this comprehensive package, eliminating the need to source components from multiple suppliers and ensuring all parts are engineered to work seamlessly together.
Technical Performance
The TRX-4M Long Arm Lift Kit represents advanced suspension engineering optimised specifically for the TRX-4M platform. The combination of revised shock mounts and longer suspension links creates a carefully calculated system that accommodates the higher ride height whilst preserving the suspension geometry that makes the TRX-4M such a capable rock crawler. The kit's engineering ensures that increasing ground clearance doesn't compromise suspension travel, articulation or steering response. When installed with Mickey Thompson Baja Pro XS 2.4x1.0 inch tyres—the recommended tyre specification for achieving the full 35% ground clearance increase—your TRX-4M gains dramatically improved approach angles, departure angles and breakover angles, translating to real-world capability on technical terrain. The extended trailer hitch maintains compatibility with TRX-4M accessories, ensuring your crawler remains fully functional. Build quality throughout the kit reflects Traxxas' reputation for precision manufacturing, with all components engineered to withstand the stresses of serious rock crawling whilst maintaining the precise tolerances necessary for responsive steering and smooth suspension action.
