Traxxas Heavy Duty Short Half Shafts & Metal U-Joints RC Driveshaft - 4949X

The Traxxas 4949X heavy duty half shafts are direct-fit driveshaft components designed to replace the stock half shafts on compatible Traxxas models, including the Rustler 4x4 (49104-1). This kit includes both external-splined and internal-splined short half shafts along with metal u-joints, making it a complete driveshaft rebuild set for the affected axle positions. If you're dealing with a snapped or worn driveshaft on your Traxxas model, the TRX4949X is the correct OEM-spec replacement to get you back running.

Key Features

• Heavy duty construction offers greater resistance to stress compared to standard half shafts, suited to hard bashing and frequent use.
• Includes metal u-joints, which are the most common failure point in the driveline, so you can rebuild the full assembly in one go.
• External-splined (x2) and internal-splined (x2) short half shafts are included, covering both shaft types needed for the compatible axle.
• OEM Traxxas fitment means these install directly without modification using the existing hardware on your model.
• Having a spare set on hand reduces downtime at the track or bashing spot after a driveshaft failure.
