Kartboy Rear Diff Bushings Soft

 Ever shift super fast and hear a clunk from the rear of your whip? Yeah? That’s because the rear differential is moving around on squishy bushings.

Stop the movement madness with our harder bushings. These sandwich the rear sub-frame outriggers, and eliminate some of the squishiness.

These aren’t the super-hard race version, but they’re definitely stiffer than stock. They’re still comfortable for every day, but you may experience a slight increase in NVH. You have been forewarned.
