INJORA Stainless Steel Drive Shaft for 1/10 RC Crawlers – SCX10, TRX4, Redcat Gen8 (84-102mm Adjustable)
INJORA Stainless Steel Drive Shaft for 1/10 RC Crawlers – SCX10, TRX4, Redcat Gen8 (84-102mm Adjustable)
This INJORA drive shaft is a heavy-duty upgrade for 1/10 scale RC crawlers, built from stainless steel for corrosion resistance and long life. It features a universal joint design with splined engagement that fits a 5mm output shaft, and includes 4mm set pins for attaching to the pinion and transmission. The shaft length adjusts from 84 to 102mm, suiting popular models like the Axial SCX10 90046, AXI03007, TRX4, and Redcat Gen8. Before ordering, measure the distance between your transmission and axle to ensure proper fit.
What Makes This Drive Shaft Different?
Unlike stock plastic shafts, this INJORA unit uses stainless steel throughout. That means it resists rust and stands up to rocks, mud, and constant flexing. The universal joint style provides smooth power transfer even at extreme articulation angles, while the splined connection locks onto the output shaft securely. The included 4mm set pins let you fasten it to both the pinion and transmission output without needing extra hardware.
Compatibility and Fit
This shaft is designed for 1/10 RC crawlers. Confirmed compatible models include:
- Axial SCX10 90046
- Axial AXI03007
- TRX4
- Redcat Gen8
Always measure the required length (center-to-center of the joints) before purchasing. The adjustable range is 84–102mm, so it will fit many custom builds too. It accepts a 5mm output shaft diameter; check your vehicle's specs if you're unsure.
Installation Notes
Fitting is straightforward. Use the two included 4mm set pins to secure the shaft to your transmission output and pinion gear. Tighten them firmly but avoid over-torquing. The universal joints are pre-greased, but you may want to add a drop of light oil after a few runs. No special tools are required – just a hex driver for the set pins.

Frequently Asked Questions
Will this fit my Axial SCX10 II?
It fits the SCX10 90046 and AXI03007. If your SCX10 II has the same transmission and axle spacing, it should work – but confirm the length range (84–102mm) matches your center-to-center distance.
Is the shaft completely stainless steel?
Yes, the main shaft and joint bodies are stainless steel. The set pins are also steel. This construction prevents rust and adds weight for better crawling traction.
Do the universal joints require maintenance?
They come lubricated. After several runs in water or mud, you can re-grease them. Otherwise, they run clean with minimal upkeep.
What if my needed length is outside 84–102mm?
This shaft only adjusts within that range. If you need a shorter or longer driveshaft, look for INJORA's other offerings or measure carefully to avoid a mismatch.
