Traxxas Rear Extreme Heavy Duty Driveshaft Assembly 6852A

The Traxxas 6852A is a complete rear Extreme Heavy Duty driveshaft assembly designed as a direct replacement or durability upgrade for compatible Traxxas RC cars and trucks.

Its reinforced composite U-joint construction adds material in critical high-stress areas for greater strength than standard composite driveshafts while retaining low rotating weight and affordable replacement costs. The assembly arrives fully assembled with the screw pin included, helping reduce installation time.

One driveshaft is supplied and can be installed on either the left or right rear side of a compatible vehicle. Two assemblies are required when replacing or upgrading both rear driveshafts.

Features

• Extreme Heavy Duty Construction: Reinforced composite components add strength in critical high-load areas
• Rear Driveshaft Assembly: Designed for the rear axle position on compatible Traxxas vehicles
• Fits Either Side: Suitable for the left or right rear position
• Fully Assembled: Supplied pre-built and ready to install
• U-Joint Design: Provides the articulation required as the suspension moves through its travel
• Composite Shaft Construction: Combines durability with lower rotating weight than many steel alternatives
• Metal Stub Axle Components: Provides secure wheel and drivetrain engagement
• Complete Replacement Assembly: Replaces the driveshaft as a complete unit rather than requiring individual shaft components to be assembled
• Screw Pin Included: Includes the required screw pin for installation
• Direct Replacement Fitment: Used as a factory replacement part on selected Traxxas models
• Upgrade Application: Can replace selected standard-duty Traxxas rear driveshafts on compatible vehicles
• Serviceable Drivetrain Component: Useful as a workshop spare for vehicles exposed to frequent jumping, impacts or high-power operation
• Genuine Traxxas Part: Manufactured to suit compatible Traxxas suspension and driveline dimensions

FAQ

Does the Traxxas 6852A fit the left or right rear side? It fits either the left or right rear position on compatible vehicles.

How many driveshafts are included? One complete rear driveshaft assembly is included. Order two when replacing both rear driveshafts.

Is the driveshaft supplied assembled? Yes. It arrives fully assembled and ready to install.

Is the screw pin included? Yes. One screw pin is supplied with the driveshaft assembly.

Is the Traxxas 6852A made from steel? No. It is an Extreme Heavy Duty composite driveshaft assembly with metal axle components. Traxxas steel driveshaft options are separate products.

What is the difference between standard heavy duty and Extreme Heavy Duty driveshafts? The Extreme Heavy Duty design adds composite material in critical areas to improve strength under hard acceleration, jumping and general bashing loads.

Can this replace Traxxas part 6852X? It is commonly used as an upgraded rear driveshaft on selected vehicles originally equipped with 6852X. Confirm compatibility with the exact vehicle revision before ordering.

Will this fit a two-wheel-drive Traxxas Slash? It is listed as an accessory or upgrade for selected Slash 2WD configurations. Check the vehicle’s model number, suspension setup and exploded parts diagram because Traxxas has produced multiple Slash revisions.

Does it fit a Traxxas Rustler 2WD? Some retailer fitment databases list additional 2WD applications, but model revisions vary. Confirm part 6852A in the vehicle-specific parts diagram before purchase.

Is this a front or rear driveshaft? This is the rear assembly. Traxxas 6851A is the corresponding Extreme Heavy Duty front driveshaft used on selected compatible models.

Is a steel driveshaft better? Steel driveshafts may handle higher power and extreme loads, but they are heavier and more expensive. Composite Extreme Heavy Duty shafts provide a practical balance of strength, low rotating mass and replacement cost for many users.

Why do rear driveshafts break? Common causes include hard landings under throttle, excessive driveshaft angle, seized suspension components, oversized tyres, high-power upgrades and applying full throttle while a wheel has limited traction.

Should both rear driveshafts be replaced together? It is not always necessary. Replace any damaged shaft and inspect the opposite side for twisting, cracked joints, excessive wear or binding.

Does this part require modification? It is intended as a direct-fit component for listed compatible models. Accessory applications may vary, so confirm the correct configuration before installation.

How should the driveshaft be maintained? Keep the joints clean, inspect the composite parts for cracks or twisting and check that the suspension and hub bearings move freely without binding.

Important Notes

• One driveshaft assembly is supplied, not a pair.
• The assembly fits either the left or right rear position on compatible vehicles.
• Two units are required to replace both rear driveshafts.
• This is a rear driveshaft; it is not the corresponding front assembly.
• The driveshaft is reinforced composite and should not be described as an all-steel shaft.
• Check the vehicle model number and exploded parts diagram before ordering.
• Traxxas model names may cover multiple generations with different factory components.
• Do not force the shaft into incompatible suspension or differential components.
• Check that the driveshaft telescopes and articulates freely after installation.
• Confirm that the screw pin is secure before operating the vehicle.
• Use thread-locking compound only on metal-to-metal fasteners and only where recommended by Traxxas.
• Do not apply thread-locking compound to plastic threads.
• Inspect the suspension arms, hub carriers, bearings and differential outputs when replacing a broken driveshaft.
• Avoid applying full throttle while the vehicle is airborne, inverted or while a wheel is obstructed.
• Oversized or heavy tyres can increase stress on driveshafts, differentials and bearings.
• High-power motor and battery upgrades may exceed the intended load capacity of composite drivetrain parts.
