Bearing Upgrades Matter On your Slash

Why Bearing Upgrades Matter On A Slash
The Slash drivetrain contains bearings throughout:
- Wheel hubs
- Transmission
- Differential assemblies
- Steering system
- Slipper clutch area (Nitro)
When bearings begin to wear, friction increases across the entire vehicle.
High-quality bearings help:
- Reduce rolling resistance
- Improve acceleration
- Increase runtime
- Reduce motor strain
- Improve drivetrain efficiency
- Increase durability
Even small improvements in friction reduction can make a noticeable difference.
Rubber Sealed Bearings Are Best For Most Slash Owners
For most Traxxas Slash applications:
Rubber sealed bearings are the best overall choice.
Why?
Because the Slash is commonly used for:
- Off-road bashing
- Dirt tracks
- Gravel
- Wet grass
- Mud
- Skate parks
Rubber seals help keep out:
- Dirt
- Dust
- Water
- Sand
This dramatically increases bearing life in real-world RC conditions.
Metal Shielded Bearings vs Rubber Sealed Bearings
Metal Shielded Bearings (ZZ)
Advantages:
- Slightly lower rolling resistance
- Higher free-spin potential
Best for:
- Cleaner racing environments
- Indoor tracks
- High-speed applications
Rubber Sealed Bearings (RS)
Advantages:
- Better contamination protection
- Longer life
- Reduced maintenance
- Better durability in harsh environments
Best for:
- Bashers
- Backyard driving
- Off-road use
- Wet conditions
For the majority of Slash owners, rubber sealed bearings are usually the better option.
What About Ceramic Bearings?
Ceramic bearings are popular among some racers because they can offer:
- Reduced friction
- High RPM capability
- Corrosion resistance
However, for most real-world Slash driving:
- Durability
- Seal quality
- Contamination resistance
matter more than ultra-high precision.
Many bashers actually prefer high-quality steel ABEC 3 sealed bearings for long-term reliability.
Why ABEC 3 Bearings Work So Well In The Slash
There’s a common misconception that the highest ABEC rating is always best.
In RC vehicles like the Slash:
- Dirt contamination
- Shock loads
- Water exposure
- Heavy impacts
can actually make ultra-tight tolerance bearings wear faster.
ABEC 3 bearings provide:
- Excellent smoothness
- Reliable tolerances
- Better contamination tolerance
- Long service life
That balance makes them ideal for most Traxxas Slash setups.
This is why the majority of FastEddy Bearings kits use ABEC 3 bearings.
Signs Your Slash Bearings Need Replacement
Watch for:
- Rough wheel spin
- Grinding sounds
- Reduced top speed
- Hot motor temperatures
- Sloppy drivetrain feel
- Rusty bearings
- Excessive resistance
If ignored, worn bearings can eventually damage:
- Axles
- Transmission components
- Differentials
- Motors
- ESC systems
Why Complete Bearing Kits Are Better
Buying individual bearings can be:
- Time consuming
- Confusing
- Easy to mismeasure
Complete model-specific kits eliminate the guesswork.
Benefits include:
- Every bearing included
- Exact fitment
- Faster installs
- No size research
- Consistent quality
For Traxxas Slash owners, complete kits are the easiest and most reliable upgrade path.
Best Bearing Setup For Most Traxxas Slash Owners
For the majority of drivers, the best setup is:
High-quality rubber sealed ABEC 3 bearings
This combination provides:
- Excellent durability
- Smooth performance
- Good contamination resistance
- Long life
- Excellent value
Perfect for:
- Bashing
- Racing
- Backyard driving
- Skate parks
- Dirt tracks
- General RC use
Final Thoughts
The Traxxas Slash is built to take abuse, but the right bearings make a huge difference in how the truck performs and how long drivetrain components last.
Upgrading from stock bearings can improve:
- Speed
- Runtime
- Smoothness
- Efficiency
- Reliability
For most Slash owners, rubber sealed ABEC 3 bearings provide the ideal balance of performance and durability in real-world RC conditions.
