TRAXXAS TRX-4 Traxx Deep Terrain Track Set
Kit Contents:
- TRX-4 Traxx (2 front, 2 rear)
- 2.5x12mm cap-head screws (8)
- 17mm wheel wrench
Recommended for optimal performance (sold separately):
Part No.| Description
2250| Servo, digital high-torque 330 coreless, metal gear (ball bearing),
waterproof
2255| Servo, digital high-torque 400 brushless, metal gear (ball bearing),
waterproof
8247X| Servo horn, steering, metal/ 3×14 BCS (1)
2262| BEC, complete (includes receiver box cover and seals)
Note: The vehicle body, front/rear bumpers, or the rock sliders may require minor trimming for proper clearance after installation of the Traxx drive units. A travel limiter has been pre-installed in the rear shocks on the drive units to minimize the amount of trimming needed on the body. For more track articulation on uneven terrain, remove the travel limiter; additional body trimming may be required. Install the TRX-4 Long Arm Lift Kit (part
8140, 8140R, or 8140X, sold separately) for additional height and clearance
with the body.
CAUTION: USE LOW GEAR
On models equipped with two-speed transmissions, drive with the transmission
in low gear to prevent overheating and permanent motor damage. On models
equipped with single-speed transmissions, the stock gearing (17-T pinion and
39-T spur gear) is suitable for general use in most terrain with NiMH or 2s
LiPo batteries; for mud or snow use, or when using a 3s LiPo battery, you must
replace the stock gearing with an 11-T pinion and 45-T spur gear prior to
driving.
Instructions
Driving Tips:
- Keep the drive teeth on the interior of each rubber track clear of debris to prevent the track from shifting out of position or derailing during operation.
- Occasionally, the drive wheel may skip on the drive teeth of the track. This is normal and will not cause damage to your truck. Check for any obstructions and/or reposition the truck before continuing.
- Observe the rollover height when driving over tall obstacles. Do not attempt to climb obstacles that are taller than the rollover height of the Traxx (Fig. A). Be careful when reversing. The trailing wheel has a much lower rollover height than the leading wheels; some obstacles will be too tall for the trailing wheel.
- Increased traction from the rubber tracks may cause your truck body to lean to one side while driving through deep snow or thick mud. This is called torque twist. Installing stiffer suspension springs can reduce torque twist in the chassis and provide additional stability.
Maintenance
- Always clean debris from the Traxx drive units after running, including snow buildup, mud, etc. Spray all metal components, screws, bearings, and bushings with WD-40® or similar water displacing light oil. It is best to remove the rubber tracks to gain access to all areas and to allow for complete cleaning of the assemblies.
- Clean the drive units using a garden hose with a spray nozzle. If a garden hose is not accessible, running the Traxx in clear water, such as a stream or shallow pond, will remove much of the accumulated mud. Blow all remaining water from the track assemblies with compressed air.
- DO NOT allow mud to dry on the drive units, as this will cause the assemblies to seize up and require full disassembly and thorough cleaning.
- Refill the anti-rotation shocks (oil dampers) with 40wt silicone shock oil as necessary.

Track Tension Adjustment
Note: The track tension has been preset at the factory and should not
require adjustment. If more tension is desired, remove the tension bar and
adjust the tension.
- Remove the 2.5x23mm cap screw from the track tension bar (T1).
- Dislodge the tension bar and fold it onto the chassis; remove the chassis from the track (T2).
- Unscrew the tensioner (T3) to the desired track tension (2.5mm is the factory setting) (T4).
- Reinstall the components in reverse order.
CAUTION: Be cautious when adjusting tension; too much tension will
result in very high drivetrain loads, motor failure, and/or premature wear on
track components.
