INJORA Steel Heavy-Duty Drive Shaft for 1/10 RC Crawlers (104-139mm)
This INJORA steel heavy-duty drive shaft is built for 1/10 scale RC crawlers, including the Axial SCX10 90046, AXI03007, TRX4, and Redcat Gen8. It measures 104 to 139 mm in length and weighs 44 g, with a 5 mm inner diameter and an 8.8 mm center shaft diameter. The hardened steel construction and splined engagement help transmit torque reliably during crawling.
Will this drive shaft work with my SCX10?
Yes, it fits the Axial SCX10 90046 and AXI03007, as well as TRX4 and Redcat Gen8. The universal joint style and six available length sizes (this one covers 104–139 mm) make it versatile for various chassis setups. The splined end fits 5 mm output shafts, and included 4 mm set pins secure it to the pinion and transmission.
