CR 7075 EHD Knuckle, C-Hub & Rear Axle Carrier Set | Slash, Rustler, Stampede, XO-1 & More
(SEE FULL COMPATIBILITY LIST BELOW)
This is not a cosmetic upgrade.
This is a structural reinforcement for drivers who break stock parts, push power harder, and expect their suspension geometry to stay locked in when things get violent.
The Cobra Racing EHD Knuckle, C-Hub & Rear Axle Carrier Set is engineered for the Traxxas 4X4 platform to eliminate flex, reduce slop, and dramatically improve durability under high-load bashing, speed runs, and hard landings. Precision-machined from high-grade aluminum and built around real-world failure points of the OEM components, this set is designed to survive where stock parts give up.
If you run power, traction, and aggression — this is mandatory hardware.
What This Set Does
-
Stiffens the entire hub, C-hub, and axle interface
-
Eliminates flex found in stock composite components
-
Improves bearing alignment and longevity
-
Maintains suspension geometry under load
-
Handles high torque, big jumps, and heavy wheels
In short: your truck tracks straighter, survives harder hits, and stays together longer.
🛠️ Engineering & Materials
-
CNC-machined high-grade 7075 aluminum
-
Precision bearing bores for consistent fitment
-
Reinforced geometry at known stress zones
-
Anodized finish for corrosion resistance and longevity
-
Tight tolerances to reduce play and slop over time
Every edge, chamfer, and pocket is purposeful — built for strength first, looks second (the looks just happen naturally).
🔥 Why Upgrade to Cobra Racing EHD Components
Stock knuckles, C-hubs, and axle carriers are some of the first failure points on Traxxas 4X4 trucks when power and grip increase.
This upgrade:
-
Prevents hub and carrier flex under acceleration and braking
-
Reduces bearing walk and premature wear
-
Improves steering precision and suspension consistency
-
Holds alignment after hard impacts
-
Survives abuse that shatters stock components

⚠️ Important Installation Note (Read This)
For non BL-2S models, EHD CVD driveshafts are REQUIRED to install this set.
This is because:
-
EHD components use 6mm bearings
-
Standard driveshafts are designed for 5mm bearings
-
Installing standard CVDs will result in excessive play and a loose fit
If your truck is not currently equipped with EHD CVD driveshafts, you must upgrade to either OEM Traxxas EHD CVDs or Cobra Racing EHD CVD driveshafts to complete the installation.
Standard driveshafts are not compatible with this set.
📦 What’s Included
-
Front EHD steering knuckles (left & right)
-
Front EHD C-hubs (left & right)
-
Rear EHD axle carriers (left & right)
-
Complete hardware kit
-
Full ABEC-5 bearing set for a complete install
No hunting for bearings. No guessing.
Everything needed to complete the upgrade is included.
💥 Who This Is For
-
Bashers who send it without hesitation
-
High-power setups running aggressive gearing
-
Drivers tired of replacing stock hub components
-
Builders who want strength without sacrificing precision
If you drive gently, this is overkill.
If you don’t, this is exactly what you want.
Final Word
The Cobra Racing EHD Knuckle, C-Hub & Rear Axle Carrier Set is a foundational upgrade — the kind you install once and forget about because it simply doesn’t fail.
No flex.
No excuses.
Just hardware that matches how you actually drive.
