Whether you're fine-tuning balance or going all-in on performance, choose from three setup options to match your build. Easy to install, tested in the field, and finished to the high standard you expect from BATRAZZI.

Performance Benefits of Brass Axle & Portal Housings

Lower Center of Gravity– Adds weight where it counts: down low. This helps your rig stay planted and reduces the chance of rolling on tough climbs and side-hills.
Increased Forward Bite– Puts more pressure on the tires for stronger pull over loose, rocky, or uneven terrain.
Balanced Weight Distribution– Fine-tune front-to-rear bias for better control on both ascents and descents.
Reduces Torque Twist– Cuts down on unwanted chassis roll and wheel lift during throttle bursts.
Smoother Crawling Performance– The added mass helps your suspension settle and soak up terrain instead of bouncing off it.
Boosted Durability– Brass housing doesn’t flex under load and takes hits better than plastic—less flex, fewer failures.
Rock-Solid Precision– CNC-machined to exact specs for a tight, no-fuss fit that performs under pressure.
 

Which Set Should You Choose?

Axle HousingCovers Set
Adds serious weight straight to the core of your rig. Improves overall stability and lowers the center of gravity at both ends. A solid upgrade for balanced crawling performance across any terrain.
Front Portal Axle Housing Set (Left & Right)
Shifts weight to the front where you need it most on climbs. Helps your front tires bite harder and keeps your nose down on steep approaches.
Rear Portal Axle Housing Set
Keeps your tail grounded and helps prevent the rear from kicking up on descents. Great for improving control on technical downhill sections and sharp breakovers.
Want the Full Effect?
Run the full set for max stability, better traction all around, and the most confident crawl your FCX10 K5& LC80 Pro has ever felt. It’s the upgrade your rig deserves.
