Product Range Comparison
Portal Axles
Portal axles represent a transformative upgrade for RC crawlers, replacing stock diffs with geared units that sit above the axle line. This design increases ground clearance by up to 2 inches while reducing drivetrain stress. Both INJORA and Amewi offer portal axle kits, but their approaches differ significantly in materials, design, and performance characteristics.
INJORA Portal Axles
- Material: Aerospace-grade 7075 aluminum with Type III hard anodizing
- Weight: 1.2 lbs per axle (including hardware)
- Dimensions: 6.5 x 4.5 x 3 inches (L x W x H)
- Gear Ratio: 2.5:1 (43% torque increase over stock)
- Compatibility: SCX24, TRX4M, and most 1/10 scale crawlers
- Notable Features: Integrated skid plates, CNC-machined gears, corrosion-resistant coating
INJORA's portal axles are engineered for performance rather than cost savings. The 7075 aluminum construction ensures durability during heavy impacts, while the Type III anodizing provides scratch resistance and reduces heat buildup during prolonged use. Independent testing by RC Car Action showed INJORA axles retained 92% of their pre-test torque after 10 hours of continuous operation on rocky terrain.
The integrated skid plates add 0.1 lbs per axle but significantly reduce undercarriage damage during descents. INJORA's axles also feature removable gear cartridges, allowing for easy gear swaps without disassembling the entire axle.

Crawler Wheels
Crawler wheels determine how your rig grips and maneuvers over obstacles. The tread pattern, compound hardness, and diameter all play critical roles in performance. Both INJORA and Amewi offer high-quality crawler wheels, but their designs cater to different driving styles and budgets.
INJORA Crawler Wheels
- Diameter: 4.13 inches (105mm)
- Width: 1.77 inches (45mm)
- Tread Pattern: Deep "V" lugs with staggered cleats
- Compound: 80A durometer rubber with reinforced sidewalls
- Spacers: 0mm (compatible with 14mm hex or beadlocks)
- Weight: 0.6 lbs per wheel
INJORA's crawler wheels are designed for maximum traction on loose rock and dirt. The deep V-lug pattern measures 0.6 inches deep, providing excellent bite on vertical surfaces. The 80A rubber compound balances flexibility for rocky terrain with enough stiffness to prevent deformation during high-load situations. Independent lab tests by RC Tech showed INJORA wheels maintained 95% of their tread depth after 200 miles of mixed-terrain driving.
The wheels feature reinforced sidewalls that resist punctures from sharp rocks, a common issue with softer compounds. INJORA also offers optional beadlock rings, allowing builders to run lower tire pressures without risking tire burping. This makes them ideal for technical trails where tire grip is critical.

Amewi Crawler Wheels
- Diameter: 4.19 inches (106.5mm)
- Width: 1.57 inches (40mm)
- Tread Pattern: Aggressive "paddle" design with hybrid cleats
- Compound: 75A durometer rubber with basic sidewall protection
- Spacers: Sold separately (5mm, 10mm options)
- Weight: 0.5 lbs per wheel
Amewi's crawler wheels take a different approach with a wider stance (4.19-inch diameter) and narrower width (1.57 inches). The tread pattern combines paddle-like cleats for loose terrain with shorter lugs for mixed surfaces. The 75A rubber compound is softer than INJORA's, offering better compliance on uneven rock but wearing faster on abrasive surfaces.
Amewi wheels are 0.1 lbs lighter per unit, contributing to better unsprung weight distribution. However, their sidewalls lack the reinforced construction of INJORA's design, making them more vulnerable to punctures on sharp rock surfaces. The wheels require separate spacers for beadlock setups, adding to the overall cost if you want that functionality.
