About the Diamond Lay Down Servo Portal Axle


Clearance & Performance Boosted

The Injora Aluminum Diamond Lay Down Servo Portal Axle Set for Traxxas® TRX-4M® raises the pumpkin for superior ground clearance while maintaining realistic scale styling with its diamond-shaped design. Pre-assembled and CNC-machined from durable aluminum, these axles include hardened CVD shafts, high-strength 20CrMo alloy steel gears, and ball bearings for smooth, reliable operation, eliminating unwanted flex found in stock composite axles.

Wider Stance

With a +5mm extended design, these axles increase total width by 10mm and enhance climbing stability without overburdening the dogbone shafts. The underdrive portal gears reduce speed by 25% for controlled torque, while the increased unsprung weight and multi-material construction maximize durability, articulation, and off-road crawling performance for any TRX-4M® build.
