Upgrade the rear axle of your 1/18 Traxxas TRX-4M with this complete portal axle assembly featuring CNC-machined aluminum construction, heavy brass portal covers, and brass wheel hub hexes. The portal design increases ground clearance, while the helical ring and pinion gears provide smoother drivetrain operation. Hardened steel axle and portal shafts add strength to the assembly, while the added brass components increase unsprung weight for a more planted feel during crawling. The axle comes assembled with the gears, bearings, differential cover, shafts, and hardware needed for installation.
