Hey guys! If you've been pushing your YIKONG YK4106 on the trails as hard as I have, you know that the stock plastic axle housings take a massive beating. Scraping over jagged rocks, sliding down boulders, and taking nasty drops is all fun and games until you hear that dreaded "crack." That’s exactly why I finally decided to bulletproof my rig with the Metal Front Axle Shells and Metal Rear Axle Shells.

Let me tell you, swapping the stock plastics for these Aluminum Alloy shells is a total game-changer. The machined aluminum feels incredibly beefy in the hands. Not only does the rigid metal protect your internal gears from flexing and binding under heavy torque, but it also gives you the ultimate peace of mind. I spent the whole weekend bashing through heavy rock gardens, and these axles just brushed off impacts that would have definitely destroyed the plastic ones.

If you are tired of babying your truck on the trails and want to build a truly indestructible drivetrain base, this aluminum axle upgrade is an absolute must-have.
