Performance Testing
To objectively assess the real-world performance of INJORA and Vanquish portal axles, we conducted controlled tests across three key dimensions: durability under impact, articulation in tight terrain, and torque transfer in low-speed climbs. Our test bed was a stock SCX24 chassis with 2.2-inch tires, modified with each brand's full portal kit and identical drivetrain components (same motor, ESC, and battery).
Durability
We subjected both axles to a standardized drop test: from a height of 30 inches, the vehicle was dropped onto a granite slab, simulating a severe rock impact. Each axle was inspected for housing deformation, knuckle cracking, and gear misalignment.
INJORA Result: Minor scuffing on the aluminum housing near the knuckle interface. No cracks or deformation detected. The anodized finish held well, with only superficial wear.
Vanquish Result: No visible damage to the steel housing or knuckles. The reinforced output flanges showed zero flex. The steel driveshafts remained straight and true.
Winner: Vanquish. The steel housing and hardened components clearly outperform aluminum in impact resistance, making Vanquish the better choice for drivers who frequently encounter sharp rocks or ledges.
Performance on Different Terrains
We evaluated each axle system on four distinct terrains: smooth rock ledges, deep mud pits, loose sand dunes, and steep inclines (30°).
- Rock Crawling: Both systems excelled, but Vanquish's higher gear ratio (3.36:1 vs. INJORA's 3.00:1) provided significantly more torque, allowing the rig to inch up vertical ledges with minimal throttle input. INJORA required slightly more throttle and was more prone to wheel slip on polished granite.
- Mud: INJORA's lighter weight reduced body roll during aggressive throttle bursts, improving forward momentum in deep mud. Vanquish's extra mass slowed recovery slightly, but its torque advantage helped it power through sticky sections more reliably.
- Sand: The difference was negligible. Both axles maintained consistent articulation and traction, with only minor differences in wheel speed due to gearing.
- Steep Incline (30°): Vanquish's 3.36:1 ratio gave it a clear edge, allowing the vehicle to maintain traction and climb without stalling. INJORA required careful throttle management and occasionally lost grip on loose soil.
Summary: Vanquish leads in torque-heavy, low-speed scenarios (rocks, steep climbs), while INJORA offers better agility in dynamic terrains like mud and sand.
